ITS ALMOST FOSSIL NOVEMBIRB!!!!!
Tumblr media
We're going to have a CELEBRATION of FOSSIL NEORNITHINES for this November!!! The extinct members of the only group of dinosaurs we have today!
Each day will have a prompt inspired by the evolution of crown-birds and the amazing forms they have taken over the past 68 million years!
You can respond to each day's prompt however you wish - with drawing and painting, writing, sculpting, music, videos, whatever! Just tag it "#Fossil Novembirb" for me to find it, and it'll get reblogged!
I'm so excited to see the art you guys create!
NOVEMBER 1 - THE CHOSEN ONES
Crown-Birds (Neornithes) known from the Mesozoic Era!
Options include Asteriornis, Teviornis, Vegavis, and "Styginetta"!
These are the only dinosaurs that survived the asteroid!
Theoretically there were also early Palaeognaths and Neoavians - if you want to do some spec evo and hypothesize what you think they might have looked like, go ahead! Follow your dreams!
NOVEMBER 2 - THE SURVIVORS
The earliest birds known after the K-Pg boundary!
Options include Conflicto, Tsidiiyazhi, Australornis, Qinornis, and Qianshanornis!
Birds diverged rapidly after the extinction, so also feel free to dive into spec evo into some of the forms we don't have fossils of!
NOVEMBER 3 - RACE TO THE SEA
The first Marine Neornithines and how they evolved in the early Paleocene!
Includes tons of early penguins like Waimanu, Kumimanu, Sequiwaimanu, Muriwaimanu, and Kupoupou
Also includes the first Pseudo-toothed bird, Protodontopteryx, and the earliest known Tropicbird, Clymenoptilon!
RISE OF THE PENGUINS!
NOVEMBER 4 - THE MEGAFOWL
Gastornis (aka "Diatryma", aka "Zhongyuanus") appeared in the mid-Paleocene and was a feature of the Cenozoic landscape until the end of the Eocene - so we have a whole day JUST FOR IT
Show your love for the Megafowl Gastornis! This giant herbivorous bird was fascinating, and has captured imaginations for decades because of it!
Gastornis is also present in many of the ecosystems described below, such as Willwood, Green River, and Messel, so we also just wanted to make sure people didn't keep picking Gastornis over and over again xD
NOVEMBER 5 - IT'S GETTING HOT IN HERE
The Paleocene-Eocene Thermal Maximum was the most dramatic incident of rapid global warming in the world since the Permian... until today!
It majorly affected the evolution of many things, possibly including birds!
The Willwood Formation straddles the time period of the warming, and has tons of birds that were evolving during that time period! So, for this day, create things involving birds of the Willwood Formation!
Options include the flighted Palaeognaths Lithornis promiscuus and Lithornis plebius; the possible stem-Ostrich Paragrus, the early half-screamer-half-duck Anachronornis, the early owl Primoptynx, and the fascinating stem-mousebird Sandcoleus! And many more!
NOVEMBER 6 - TROPICAL DENMARK
Birds of the Fur Formation, one of the best collections of bird fossils from the early Eocene!
Includes such friends as Scandiavis (an early shorebird), Septencoracias (an early roller), Pellornis (an early rail-esque thing), the utterly mysterious Morsoravis, and the early swift-hummingbird Eocypselus!
This was a tropical shoreline environment with many of the first members of major bird groups we see today!
NOVEMBER 7 - ANCIENT LONDON TOWN
Across the shore from Fur was the London Clay Formation, a lush tropical forest near the warm shallow ocean
In addition to a truly alarming quantity of plant fossils, this is a notable locality for early birds, featuring many early members of major groups much like the Fur Formation
Options include Dasornis (a pseudotoothed bird), Pulchrapollia (one of the Parrot-Passerines of Prey), Nettapterornis (another stem-duck), Nasidytes (an early loon), Charadriisimilis (an early shorebird), Archaeodromus (a trogon-like member of Strisores), Eotrogon (an actual early Trogon), Lithornis vulturinus (another flighted Palaeognath), Prophaethon (another early Tropicbird), and Ypresiglaux (an early owl) - and so many more!
NOVEMBER 8 - THE RAPTORS ARE BACK
Turns out "Predatory Feathered Thing with Really Sharp Foot Claws" is a very successful niche - not only was there potentially one right after the end of the Cretaceous (Qianshanornis), but other raptors were some of the first birds to succeed around the world in the Eocene
So this day is dedicated to the early raptors of the Cenozoic!
Any "raptor" from the Paleogene is valid - so here are some suggestions: Early Cariamiformes (Seriemas and Kin) like Bathornis, Dynamopterus, Strigogyps, and the first potential Terror Birds like Paleopsilopterus Early Owls like Ypresiglaux and Palaeoglaux Early Accipitriformes like Horusornis Early Falcons like Antarctoboenus, Masillaraptor, and Danielsraptor And of course the ever popular "Parrot-Passerines of Prey" like Tynskya and Messelastur
NOVEMBER 9 - GETTING A GRIP
Half of all living birds are Passeriformes - aka "Perching Birds" - but this wasn't always the case! For most of Earth's history, many other kinds of tree birds were extremely common
Where did this behemoth group of tiny dinosaurs come from? That's the subject of this day's prompt!
In the Eocene, the first birds closer to Passeriformes than to Parrots evolved, and they came in a huge variety of forms! So on Nov 9th, we're going to celebrate this group's interesting beginnings!
Options for this include Parapsittacopes, Eofringillirostrum, Pumiliornis, Psittacopes, Zygodactylus, Primozygodactylus, Psittacomimus, Sororavis, Morsoravis, and Eozygodactylus! Go wild!
NOVEMBER 10 - BAYOU IN THE BADLANDS
Back to specific ecosystems! We're visiting the world-famous Fossil Lake of the Green River Formation!
This environment, during the Early Eocene, was a thriving tropical lake and forest ecosystem filled with tons of early Neornithines as well as mammals and other animals
Gorgeous fossils have come out of this lake, showing truly amazing detail of feathers and other features for these birds!
So here you can feature Prefica (a potential early Oilbird), the flighted Palaeognath Calciavis, the stem-turaco Foro, the early mousebird Celericolius, the possible shore-bird Nahmavis, a potential cuckoo roller Plesiocathartes, the Flamingo-Duck Presbyornis, the early landfowl Gallinuloides, the swift-hummingbird Eocypselus, and the Frigate Bird Trying at being a Gull Limnofregata - and so many more!
NOVEMBER 11 - A NEW DAWN
We're finally moving on to the middle Eocene - and the Messel Lake ecosystem, famous from the first episode of Walking with Beasts (hence the name of the day)!
(If you're going "wait, that episode acts like nothing happened between the K-Pg and Messel, but here you have 10 days worth of stuff" .... yeah. Walking With Beasts skipped the Paleocene and early Eocene and I am... very pissed. Still.)
You know about the tons of early mammals from this tropical lake ecosystem, but it was filled with tons of early birds as well!
There's the early ostrich Palaeotis, the crane-rail Messelornis, the almost-flamingo Juncitarsus, the freshwater Booby Masillastega, the early hoopoe Messelirrisor, Selmes (a mouse bird with stubby toes), the early ibis Rhynchaeites, the early nightbird Hassiavis, the early swift Scaniacypselus, an early roller with known colors Eocoracias, and the early potoo Paraprefica - and many others!
NOVEMBER 12 - PEAK PENGUIN PARTY
As the Eocene continued, penguins achieved true megafaunal status - there were tons of them, they were huge, and they were all over the oceans of the Southern Hemisphere
While penguin diversity never did recover after the Eocene-Oligocene extinction event, this golden age deserves celebration!
Some of these fascinating peak penguins include Palaeeudyptes, Anthropornis, Icadyptes, Inkayacu, Perudyptes, and Kairuku!
NOVEMBER 13 - FRENCH SAVANNAH
As the Eocene began to dry up and cool down, plains grew across the world where the tropical forests once had been
One of the most famous later-Eocene fossil sites for birds is the Quercy Phosphorites location, a French formation with tons of interesting fossil birds!
Here we start to see the early forms of Neornithine Dinosaurs we saw in the Paleocene-Early Eocene diverge and specialize further - often in particularly weird or interesting ways!
So here we have the duck-ish chicken Paraortyx, the secretarybird Pelargopappus, you can also bring back Dynamopterus from earlier, there is the stem-chicken Quercymegapodius as well as stem-parrots like Quercypsitta, the seriema-like Strigogyps, the sandgrouse relative Archaeoganga, Archaeotrogon shows up again, the swift relative Aegialornis, a potential woodpecker relative Sylphornis, and more owls like Palaeoglaux! Lots of cursorial predators in this ecosystem!
NOVEMBER 14 - LOST IN THE WOODS
As the Oligocene dawned, forests did grow back in Europe, though they were now temperate and dry as opposed to the paratropical rainforests of before
This lead to wide diversification of tree-dwelling birds, and so here we will celebrate the birds of the Oligocene of Europe!
We start to really see modern-esque birds at this point, though of course we still have 30 million years of evolution to go!
Here you can feature the early eagle/hawk Aviraptor, the European Hummingbird Eurotrochilus, the seabird relative Rupelornis, the early woodpecker-toucan Rupelramphastoides, the tody Palaeotodus, the proper Passerine Wieslochia, the possible shorebird Turnipax, the mousebird Oligocolius, the hoopoe Laurillardia, and the trogon Primotrogon which we know the colors of!
NOVEMBER 15 - OASIS IN THE DESERT
The Jebel Qatrani Formation of Egypt shows the beginnings of the famous African Grassland animals, as well as many early members of iconic African animal groups such as primates - and, of course, birds!
Taking place in the early Oligocene, this formation was a tropical/subtropical lowland plain filled with ponds and streams and other waterways - aka, tons of swamps surrounded by plains
As such, this place is infested with waterbirds!
Here we have a fossil relative of the Shoebill Goliathia, as well as the jacanas Janipes and Nupharanassa, the giant stork Palaeoephippiorhynchus, the herons Nycticorax and Xenerodiops, and the mystery Palaeognath Eremopezus!
NOVEMBER 16 - AMONG THE GIANTS
Once again we're just fully committing to the Walking With Beasts nostalgia bc these are the birds we wish were in it more okay we said it
Anyways there were some interesting large birds in the plains of the "Land of Giants" episode so picture these guys alongside the Indricothere etc.
In general we're covering the latest Eocene through the Oligocene of Central Asia
Here we have the enigmatic ratites Ergilornis and Sonogrus, the pseudo-toothed bird Caspiodontornis, the owl Heterostrix, and the stem-flamingo Agnopterus
NOVEMBER 17 - IF THE WIND WAS IN OUR WINGS
We all focus on penguins, but over the Cenozoic, plenty of weird birds have evolved for marine life, and boy are they bizarre!
So for Nov 17, we're focusing on the unusual marine birds of the Cenozoic!
This includes any members of the Pelagornithids - aka the Pseudo-toothed birds - as well as the Plotopterids - the Boobies that became Penguins! Pelagornis and Copepteryx are the best known taxa from each, respectively, but there are plenty more!
But that's not all! We have the flightless auks Miomancalla and Mancalla, the large flightless marine duck Chendytes, and who can forget the weird flightless marine swan Annakacygna! Tons of options to choose from!
NOVEMBER 18 - MARCHING IN THE MARSHES
We're now starting our transition from the Paleogene into the Neogene, beginning with the brackish marsh ecosystem preserved at Saint-Gerand-Le-Puy in France!
This Miocene locality preserves a wide variety of birds that are near modern, but not quite - a sort of "uncanny valley" of bird evolution, all set in a somewhat-salty somewhat-not wetland ecosystem
Options for dinosaurs here include Harrisonavis, a transitional flamingo; the early gull/tern Laricola, the enigmatic duck Mionetta, the stork Grallavis, the pratincole Becassius, the swimming-flamingo Palaelodus, the early cormorant Nectornis, the seed-eating pheasant Palaeortyx, the early loon Colymboides, and the mysterious shorebird Elorius!
NOVEMBER 19 - FERN GULLY
Riversleigh is one of the most famous fossil sites in the world, preserving the evolution of the strange and unique animals known today in Australia, during the Oligocene to Miocene transition
Most often, we focus on the bizarre mammals found at Riversleigh, and for good reason - it's a Marsupial Party! - but the birds here are fantastic as well
This ecosystem was a rich rainforest that transitioned over the period of deposition into a semiarid grassland, and covers 20 million years of animal evolution during that transition
Options for birds here include the butcherbird Kurrartapu, the fossil Sittella Daphoenositta trevorworthyi, the Mihirungs ("Demon Ducks") Dromornis and Barawertornis, the Emuwary Emuarius, the early magpie-goose Eoanseranas, the raptor Pengana with flexible ankles, the earliest known species of lyrebird (Menura tyawanoides), the corvid-like Corvitalusoides, the first known cockatoos, the flightless rail-like bird Australlus, the stiff-tailed duck Pinpanetta, the early logrunner Orthonyx kaldowinyeri, and so many more!
NOVEMBER 20 - LAND OF GIANTS
Y'all were probably wondering when we'd get to the Terror Birds and other interesting dinosaurs of South America, so - here we are!
South America, isolated from the rest of the world until the Great American Interchange, featured a wide variety of bizarre and unique animals - not just mammals, but birds and other reptiles as well!
So for Nov 20th, we're looking at the interesting dinosaurs of the "lost continent" during the Miocene epoch, prior to the invasion of North American taxa!
Any Miocene South American Terror Bird (Phorusrachid) is fair game here, so that includes Brontornis, Patagorhacos, Paraphysornis, Devincenzia, Kelenken, Phorusrhacos, Patagornis, Andalgalornis, Psilopterus, Mesembriornis, and Procariama! Note that they did not all live at the same time or even close to each other in location, so do your research on the taxa you pick!
But Terror Birds weren't the only strange dinosaurs in South America at the time! We have the large Teratorn (vulture-like-thing) Argentavis, the *giant* swimming-flamingo Megapaloelodus, the giant Anhinga Macranhinga, the rhea Opisthodactylus, the penguins Palaeospheniscus, Arthrodytes, and Paraptenodytes, the Cathartid Dryornis, the Jacamar Galbula hylochoreutes, fossil Hoatzins like Hoazinavis and Hoazinoides, the giant stork Leptoptilos patagonicus, and the owl Yarquen!
NOVEMBER 21 - FIRST OF THE MANU
Aotearoa has one of the most unique avifaunas in the world today, and I often call it "Mesozoic 2" because of its almost entirely dinosaur-dominated fauna, especially in the past
All great things have to start somewhere or when, and for Aotearoa, that somewhen was after the landmass resurfaced from the ocean for the first time in millions of years - and was quickly inhabited by all kinds of birds and other reptiles (including tuatara) in the Miocene
This ecosystem was a lake bordered by grassy wetland floodplains and subtropical forests, a bit warmer than Aotearoa today
Dinosaurs here include the early Kiwi Proapteryx, an unnamed early Moa, a truly alarming number of waterfowl including shelducks like Miotadorna, stiff-tailed ducks like Manuherikia, and the possible swan Notochen, the small swimming-flamingo Palaelodus aotearoa, pigeons like Rupephaps and Deliaphaps, an early adzebill Aptornis proasciarostratus, flightless rails like Priscaweka, the lake-wanderer Hakawai melvillei, the herons Pikaihao and Matuku, the giant parrot Heracles, proto-keas Nelepsittacus, and the New Zealand Wren Kuiornis. Tons of fun species to choose from!
NOVEMBER 22 - LAND OF CONFUSION
In the Late Miocene to Early Pliocene, the Italian province of Gargano was cut off from the mainland due to rising sea levels, turning it into an island - an island with lots of really strange birds!
This island was cut off from everything else and completely lacked large predators, allowing for a weird variety of animals to evolve and thrive prior to the island rejoining the mainland during the Ice Age
Strange birds of this ecosystem include the extremely old pigeon Columba omnisanctorum, the giant hawk Garganoaetus, the giant flightless goose Garganornis, the giant barn owl Tyto gigantea, the pheasant Palaeortyx volans, and the swift Apus wetmorei!
NOVEMBER 23 - MAKE A BIRD OUT OF YOU
The iconic animals of the Ice Age and recent prehistory had to come from somewhere, and much of this transition is recorded in the Chinese Ecosystem of the Liushu Formation, deposited between 11 and 6.4 million years ago
As grasslands expanded, this ecosystem transitioned from a forest to a wide plains, and many animals adapted for the grasslands accordingly, leading to the appearance of such mammals as Elasmotheriines, Sabercats, Hyenas, Ambelodonts, and a truly alarming quantity of hoofed mammals
Dinosaurs (Birds) adapted to this ecosystem change as well, of course! While most focus on the mammals of Liushu, we're here to showcase the interesting birds that appeared here as well!
Options here include the the very well preserved Falcon Falco hezhengensis, the vultures Mioneophron and Gansugyps, the diurnal owl Miosurnia, the vocally fancy pheasant Panraogallus, the sandgrouse Linxiavis, the Ostrich Struthio (or Orientornis) linxiaensis, and the probable-Ostrich Sinoergilornis
NOVEMBER 24 - ANCIENT SOUTH PACIFIC
Penguins are Bouncing Back! As the Miocene continued and the Pliocene began, many new types of marine birds showed up and were fossilized in locations in Chile (Pisco) and Aotearoa (Tangahoe)
Tons of interesting birds were preserved in this sort of transitional ecosystem, showcasing how birds adapted to changing conditions as the Miocene-Pliocene climatic turmoil continued
These near shore environments are probably more famous for their other animals - things like the giant shark "megalodon", as well as weird whales like Livyatan and Odobenocetops and aquatic giant sloths (like Thalassocnus) and marine crocodilians - but we're here for those dinosaurs!
Options here from the Pisco Formation include the "Toucan-Booby" Ramphastosula, the Cathartid Perugyps, the Booby Sula figueroae, Pelagornithids, Pelicans, and the penguins Spheniscus urbinai and Spheniscus megaramphus, whereas birds from the Tangahoe Formation include the narrow-beaked albatross Aldiomedes, the giant petrel Macronectes, the more regular-sized petrel Procellaria altirostris, the little penguin Eudyptula wilsonae, and the crested penguin Eudyptes atatu!
NOVEMBER 25 - LAST OF A DYING BREED
We all love Megafuana, even though they are usually the "Live Fast Die Young" kind of species - gobbling up resources and growing too big will do that to you
Usually when we hear the term "Megafauna" we think of Mammals and Non-Avian Dinosaurs, but birds have had their share too - and have lost their share as well
So, mainly to cater to the Megafauna Fanbase, here we dedicate a whole day to the giant birds of recent times - Pliocene through Pleistocene - that we have lost to the dramatic climate change of the Ice Age Era. (Those lost in the Holocene will get their own days, see below)
Options for this day include the giant ostrich Pachystruthio, the Mihirung Genyornis, the Terror Bird Titanis, the giant stork Leptoptilos robustus, the giant swan Cygnus falconeri, the giant Anhinga Giganhinga, and of course - we can't forget our friend - the last of the Pseudotoothed Birds, Pelagornis
NOVEMBER 26 - HIGH AS A KITE
In many ways, the real dinosaur winners of the Ice Age were the flying Birds of Prey, as there were many kinds of raptors during the Ice Age and they exploited the new environment expertly
Nothing like being able to traverse huge distances to find places where there are food, amiright?
So this day is dedicated to the fantastic Raptors of the Ice Age, both volant and not!
Here we have some of the last of the Teratorns like Teratornis itself, the Giant Australian Raptor Dynatoaetus, the Australian Vulture Cryptogyps, Woodward's Eagle Buteogallus woodwardi, the tiny Condor Wingegyps, the large Cuban Eagle Gigantohierax, the wandering vulture Neogyps, the Walking Eagle Buteogallus daggetti, the Giant Cuban Stilt-Owl Ornimegalonyx, and one of the last Terror Birds, Psilopterus
NOVEMBER 27 - BEGINNING OF THE END
Oh Holocene Extinctions. As upsetting as they are, they include some of the best known fossil/subfossil birds, so we decided to spend a little extra time on them than they should have based solely on the time length
Here, we highlight the early losses of the Holocene - those dinosaurs that went extinct at the start, largely due to direct human activity such as hunting in addition to the warming caused by the end of the last Ice Age/Glacial Maximum
Days will be dedicated to both Hawai'i (see below) and Aotearoa (again, below), so this is for everyone else!
So options here include the previously mentioned marine duck Chendytes, the giant flightless landfowl Sylviornis from New Caledonia, the famous Elephant Birds of Madagascar, the flightless clubbing-ibis Xenicibis, the weird puffin Fratercula dowi, the giant Bahama Eagle Titanohierax, the Californian Turkey Meleagris californica, and the flightless "Cave Rail" Nesotrochis of the Greater Antilles
NOVEMBER 28 - OLD HAWAI'I
Many, many, MANY unique dinosaurs live on islands. The islands of Hawai'i are no exception, and these islands have lost many unique and fascinating birds over the years - thanks to human activity, invasive cats, colonialism, and climate change
We couldn't possibly ignore them, so for this day, we are hilghlighting these amazing animals found across the archipelago
There are tons of options, but some of our recommendations include the reverse-platypus/Mole Duck Talpanas, the Stilt-Owl Grallistrix, the flightless ibis Apteribis, the Moa-Nalo like Chelychelynechen, Ptaiochen, and Thambetochen, the Wood Harrier Circus dossenus, Hawai'ian Honeycreepers like Drepanis, Aidemedia, Hemignathus, Chloridops, Akialoa, Rhodacanthis, Dysmorodrepanis, Telespiza, and Vangulifer, the Oloma'o and ʻĀmaui thrushes, ʻōʻō's/Hawai'ian Honeyeaters like the Kioea, Kauaʻi ʻōʻō, and Oʻahu ʻōʻō, the giant Hawai'i Goose, the nēnē-nui/wood-walking goose, the Robust Crow, the flightless Laysan Rail, and the O'ahu Petrel
NOVEMBER 29 - OLD AOTEAROA
We're finally here: Pre-Human Holocene Aotearoa, aka Mesozoic 2, aka The Land Where Mammals Ain't Shit
I love Aotearoa so much. Why wasn't I born there. The universe isn't fair.
The ecosystems were very similar to today - podocarp forests and southern beech forests, grass and tussock plains and shrublands, and plenty of coastal habitats, all usually temperate in terms of climate
All named Moa are fair game. All of them, all named members of Dinornithiformes. So the North Island Giant Moa, the South Island Giant Moa, the Bush Moa, the Eastern Moa, the Broad-Billed Moa, the Heavy-Footed Moa, Mantell's Moa, the Crested Moa, and the Upload Moa. Follow your Moa-Filled Dreams!
Obviously there were more than Moa - not just the living species of Aotearoa still with us, but tons of other extinct forms for Fossil Novembirb. This includes the Adzebills, Haast's Eagle (of course), the whēkau/Laughing Owl Ninox albifacies, the New Zealand Goose Cnemiornis, the New Zealand Owlet-Nightjar, the mehonui Diaphorapteryx, the Long-Billed Wren Dendroscansor, the piopio Turnagra, and the Huia
NOVEMBER 30 - SIXTH EXTINCTION
And, for our last day, we cover recent Holocene extinctions (not on Hawai'i or Aotearoa) - the birds/dinosaurs we have lost in the living past, due largely to colonialism, capitalism, globalism, and climate change
Any bird extinct since 1492 not previously covered is fair game, and there are a lot of them. Today, we honor them, however we can.
Some suggestions include the Dodo (of course), the Cuban Macaw, the Pink-Headed Duck, the Northern Curlew, the Great Auk, the Passenger Pigeon, the Carolina Parakeet, the Ivory-Billed Woodpecker, the Labrador Duck, the Saint Helena Hoopoe, and the Spectacled Cormorant; though there are of course many otherse to choose from as well
Kind of a bummer note to end on, but here we are
Living Birds already get tons of time and attention, so we really don't want to include them here - we love them, but the fossils of the Neornithes world deserve love too! So we tried to cover all of the bases, as best as we could!
Remember, Wikipedia, the Paleobiology Database, The Works of Gerald Mayr, the third volume of "Earth Before Us", and the blogs of myself and @albertonykus and @otussketching are all fantastic resources to look for information about these wonderful animals! Also check out Through Time and Clades' "Dinosaurs: The Second Chapter" series and the Raptormaniacs blog from Albert as well!
HAVE FUN! CREATE WHAT YOU DREAM! AND LOVE CENOZOIC DINOSAURS!
HAPPY FOSSIL NOVEMBIRB!

31 Mermaids, 2- Ghost
Tumblr media
Ghost mermaids have been puzzling scientist and occult scholars; not really for what they could teach about death, but for what they seem to imply about the history of life.
To date, interviewed mermaids have never recognized a known ghost as a specific formerly individual. However, besides them only appearing at night and being mostly incorporeal, one ghostmaid has allegedly been tracked to her "manifestation site", which revealed a gigantic skeleton, or possibly several.
No proper exploration has been carried out yet, but what perplexes researchers is how the bones seem to be fossilized, embedded in layers of rock that have been dated to many different periods, invariably earlier than the K-Pg extinction boundary.
Ghostmaids sing like merfolk, but their vocal range extends far into the infrasound. This is theorized to be at least partially due to their size.
Neither land humans nor merfolk have been able to recognize a language or to ascertain whether words are present at all in the songs.
To date, one attempt is alleged to have been made at verbal communication by an independent researcher using advanced recording equipment and underwater microphone.
No information exists on the results, or the researcher's whereabouts.

you ever think about the K-Pg boundary. all over the world, this barely visible line only really distinct from the sediments surrounding it because it has more iridium in it. dinosaurs under, no dinosaurs above. something terrible happened here. the chicxulub impact, a planetary scale traumatic event forever carved into the earth.
but it's so easy to miss. it's just rocks, same as all other rocks until you look closer. this massive event was so quick in destroying everything that its only remaining trace is a few centimeters of sediments. when it was discovered, the pushback was swift and loud: prove it. prove that this happened. prove that the earth suffered. prove you know why it was forever changed.
was it because it's really that hard to believe? that of all popular theories at the time, the most improbable would turn out to be right? the crater is buried, half under the sea, and so big we mistook it for hills. the scar left behind is so impossibly small and yet it's everywhere.
the earth has long moved on from the dinosaurs, and yet she will never forget. she can't. because there will always be that thin line of rock with more iridium in it than you'd expect.

Archeology in Remnant must be wild.
that is the literal plot of the grimm campaign hdjghdhd
but no yeah for real. on the one hand you’ve got tiny fragments of vitrified human remains embedded in the equivalent of the fucking K-Pg boundary and on the other, even the most remote parts of anima are built on top of long-buried ruins if the sprawling sewer under brunswick farm is any indication. and then you have who knows how many mountain glenns and oniyuris scattered across history. the ruins of the ozlem kingdom are out there somewhere (probably not too far from kuchinashi, if the grimm campaign is taken to be canon!). the planetary core is strongly implied to be grimm liquid in V8 which means that volcanic eruptions on top of everything else probably spew grimm everywhere—imagine what the pompeis of this world must look like, if it’s possible to discover them at all. and then you have a reincarnating wizard desperately trying to scrub his immortal ex wife out of the historical record, often actively fabricating false history to do so. remnant’s archaeologists are braver than any us marine

You don’t really appreciate how unbelievably long the Cretaceous lasted until you've had to cut it out of a piece of cardboard in four parts because at a 3 cm=1 million years scale, it's well over 2 metres in length. I don't think I ever realised that we are currently closer to the end of the Cretaceous than the end of the Cretaceous was to the start of the Cretaceous.
I'll probably add some sort of icon at the K-Pg boundary (a little meteorite hitting the Earth?) once I'm done with the full timeline, and I'll certainly be putting up a lot of paleoart around it.

The days of creating amazing and creative dinosaur OCs with nowhere to show them off to is over! We're celebrating the new year by bringing back some old friends from the Mesozoic in this brand new prehistoric roleplay server, free from the Jurassic Park cliches and humans in general. Here, you can go wild in a speculative alternate-earth timeline that allows the three eras of the Mesozoic to exist simultaneously, alongside the implications of what dinosaurs with human level intelligence could mean for the world at large, and how different life could've been if the K-Pg extinction never happened, and by extension if mammals had never rose to dominance.
At the Extinction Boundary, you can explore custom-made lore and help forge this vast world of endless prehistoric possibilities, create unique characters, and invest in captivating plotlines that surpass the limits of mere survival alongside a community of other dedicated roleplayers and Queer/Transgender staff!
At Extinction Boundary, we offer:
A realistic RP that fuses realism and fantasy with a wide range of styles including paragraph, semi-paragraph, and script/banter, so you can roleplay however you are most comfortable
Extensively developed and open-ended worldbuilding, so there is always something to do or someplace to explore, with lore that is influenced by community contributions
No limits or quotas on word count, activity, or character count. Roleplay as much or as little as you want, no penalty!
An easy-to-use, optional stats and dice-rolling system for fair play and realistic combat
A polished server with useful bots, beta testing for quality assurance, and attention to detail put into its organization for a streamlined and user-friendly experience
An abundance of custom aspects, including hand-drawn emojis, maps, color roles, server icon, and more
Social aspects like voice, art, and gaming chats, as well as movie nights and other events
Not interested in roleplay? Join us anyways to share artwork and OCs and a love for all things prehistoric! This server is a work of original fiction and as such may not accurately reflect all elements of the real life Mesozoic. Keep an open mind for some fantastical creative liberties that keep the world grounded yet exciting! We look forward to crossing the boundaries of extinction with you!

My face is still on a "most wanted" poster in Chicxulub.
...which is weird, since paper still hadn't been invented at the time of the K-Pg Boundary.

Hey so fun fact. Y’know the K-Pg extinction (extinction event that killed the dinosaurs, big meteor?) and how in some places you can find the layer of rock known as the K-Pg boundary (layer of debris from the impact, you can find dinosaur fossils under it but not above)? Well I can proudly say that I ate part of the K-Pg boundary. I put a piece of that rock In My Mouth. Consumed it. Honestly flavour wasn’t great it basically just tasted like dirt, texture was also Just Dirt, but still 10/10 would eat the K-Pg boundary again

No.77 Iridium - the goddess of the rainbow in platinum group
Iridium is one of the least abundant elements in the earth's crust, about one-fortieth the amount of gold.
The elements Iridium and Osmium were discovered simultaneously in 1803 by the British chemist Smithson Tennant.Born in Selby in 1761, Yorkshire, Tennant had studied medicine when he was young, but found it unaccommodated to be a doctor after graduation and finally turned to study chemistry. In 1785, at the age of 23, Tennant was elected a fellow of the Royal Society and kept digging in the field of chemistry. He made a quantitative analysis of diamond combustion experiments in 1976, which confirmed the surprising conclusion that diamond and graphite were isomers.Tenant passed away in 1815 on a bridge, near Boulogne-sur-mer, France, which collapsed while he was riding across it.

Iridium has also been implicated in an ancient Earth extinction event.Iridium is found in very small amounts in the Earth's crust, but scientists have found it very high levels in sediments at the end of the Cretaceous and the top Tertiary period (about 65 million years ago) where the dinosaurs died out, hundreds of times higher than its natural abundance in the earth's crust. At the same time, asteroids contain a lot of iridium. According to these, the American physicist Luis Walter Alvarez hypothesized that an asteroid impact wiped out 70 percent of all plant and animal species on Earth, including all non-avian dinosaurs and that much of the iridium in the Earth's crust today also came from it.Then a similar size crater, Chicxulub Crater, was discovered in Mexico's Yucatan Peninsula, besides, no dinosaur fossils have been found at the K-Pg boundary. Multiple clues further support the Alvarez hypothesis.
Tumblr media
In modern times, iridium oxides have also attracted a lot of interest over the past 10-15 years. As a heavy transition metal element with a half-filled 5d electron orbital, in theory, its oxide should exhibit metallic conductivity. However, due to relativistic effects (spin–orbit interaction) on the electron shell structure, many iridium oxides behave as insulator. These insulators have been predicted to exhibit strange electromagnetic phenomena.Compounds isolated from iridium are also of interest to the chemical community. In this compound, iridium reaches a valence of +9, the highest known oxidation state, which has never been found before. This also makes iridium the element with the widest range of oxidation states (from -3 to +9 valence).
Iridium also has excellent performance in terms of physical properties, having the second highest density (22.56 g /cm³) of all elements, only slightly lower than osmium, and the second highest melting point at 2450℃. At the same time, iridium has strong and outstanding resistance to corrosion and high temperatures, making it ideal for use in spark plugs and engine parts in the aerospace industry. Iridium is extremely scarce around the world. It is produced mainly as a byproduct of electrolytic refining of copper and nickel, only three tons a year, making it expensive.
Iridium’s  pronounce “Yi” in Chinese is the same as the one of the number “one” , which can be derived into the meaning of "always", symbolizing the persistence and pursuit of love, ideal, career and life, as well as the loyalty, unswerving and unchanging style of the Chinese people. With these special meaning, therefore, iridium metal is gradually used in the jewelry industry, and a large number of iridium jewelry has come into the public eye.

man i was gonna get shit done today but then i goofed off all morning and now i have entered waiting mode for rehearsal and all i can do is think about the k-pg boundary and that complete baby pterasaur egg they found up in north dakota that hints that pterasaurs probably popped out fully formed and ready to fly and also that one bead of weird glass that contains a bit of the chixulub meteor idk living on a planet with a whole bonkers geological history before us is so weird

Fossil Novembirb 2: The Survivors
The End-Cretaceous Extinction was one of the most devastating - and tragic - events on our planet.
In the blink of an eye, the world changed from a thriving biosphere to a decimated one. The asteroid caused worldwide wildfires, tsunamis, and the dramatic release of particles into the air that blocked out the sun.
Nothing over 25 kg could survive, because they had nowhere to hide from the devastation. Anything under that limit had to have somewhere to hide - water or burrowing worked best - and something to eat, which was easier said than done. When the plants can't eat, nothing can.
And yet, life survived - not just life, but dinosaurs themselves!
Tumblr media
Conflicto, by @otussketching
In fact, one of the first fossils we have from the Cenozoic is Conflicto, a Presbyornithid - like "Styginetta" and Teviornis yesterday! - from Antarctica
Why these dinosaurs, and no others?
They had beaks, which would have helped them to access available food sources such as seeds and spores (plant material in a protective casing)
They did not live in trees, but usually near or with water - perfect places to hide
They were powerful fliers, allowing them to escape the flames and whatever else they needed to
Other than that? Random chance.
Much of the evolution of life on this planet is down to Sheer Dumb Luck
Tumblr media
Tsidiiyazhi by Sean Murtha
What happened next was truly remarkable: an adaptive radiation of dinosaurs the likes of which is rarely seen
With all of those newly opened niches, Neornithines adapted quickly, so quickly we can't actually figure out how different major groups of Neoavians - aka, most birds - actually relate to one another.
After all, there was just *so much* free real estate!
Tumblr media
Qianshanornis by @alphynix
In fact, many of these dinosaurs evolved right back into niches that their ancestors had famously lived in - penguins show up so quickly that we're giving marine birds their own day, replacing the now-lost Hesperornithines; Tsidiiyazhi and others quickly replaced the empty tree-bird niches left behind by the lost Enantiornithines; and raptors show up quickly too, already reminiscent of the lost Dromaeosaurs.
Qianshanornis, a mysterious raptor from China, had sickle claws just like its lost bretheren! In fact, it looks like it might be a Cariamiform, a group of dinosaurs including living Seriemas and the extinct Terror Birds, which often have sickle claws like Dromaeosaurs did!
Don't fix what isn't broken, I guess!
Tumblr media
Australornis by @thewoodparable
Non-Neoavians diversified too, with fowl doing just fine across the boundary - Presbyornithids like Conflicto, as well as mysterious forms like Australornis.
Palaeognaths remain weirdly absent, but don't worry - the earilest ones will show up before the Paleocene epoch is done!
The Cenozoic begins with the Paleogene Period, which has the first epoch of the Paleocene - this was a climatic quagmire, with frequent fluctuations at the beginning before a dramatic rise in temperatures at the end. This climate confusion would affect bird evolution greatly - and lead to the diversification of many kinds, some of which we still have today!

Goes to a lecture about mass extinction in my climate change class. Suddenly remembers the k-pg boundary. Oh god the fucking dinosaurs

the great dying was the most insane extinction event bc of the scale of how bad it was and how much was wiped out but IMO the k-pg extinction was cooler just bc a) it was a giant space rock multiple miles wide and b) you can see the 5 inch wide boundary in the rock layers made of space metal and if that isnt the most metal shit youve ever seen gtfo
