Stromatolite Fossil
Tumblr media Tumblr media Tumblr media
When I first saw this stone, I was excited. I was even more excited when I found out what it was. A record of the first life forms on Earth. Information from billions of years ago. How could I not be excited? I would love to know all the information hidden inside this beautiful fossil.

Hello it's me local twitter refugee @aberrantologist and I draw dinosaurs and stuff.

This is my first post on Tumblr so I have no clue what I'm doing. Regardless, I thought it would be a good idea to share some of my art from this year. Featuring the Prehistoric Planet Nanuqsaurus family, two very gay Halszkaraptor, a hungry Helicoprion, a speculative take on the enigmatic Hupehsuchus, and of course...

...a portrait of my dear son/daughter/child Lucky who is the best dinosaur ever (factual statement) even though all they do is bite stuff and poop everywhere. Anyways, for more paleoart and the occasional bird photo, please consider dropping a follow!

Fossil evidence from the Tornillo Basin in West Texas and the Uinta Basin in Utah reveals two new species of omomyids—a family of small-bodied early primates from the Eocene epoch. The findings also clarify previously disputed taxonomic distinctions among these primates, according to researchers from The University of Texas at Austin, Des Moines University in Iowa and Midwestern University in Arizona. The study, published in the Journal of Human Evolution, significantly expands the fossil record of primates from these regions and also allowed the researchers to confirm the existence of three distinct genera of omomyids.

I think to some extent, there is value in making distinctions between groups of extinct animals based on stuff other than crown groups, like technically speaking both Ichthyornis and Triceratops are "stem birds" and yet neither of them are "crown group birds" .
Like if we go by a strict crown group definition of "bird" the phrase "non avian dinosaurs went extinct at the end of the Cretaceous " is false, Qinornis was not a crown group bird and was found in the Paleocene, millions of years after the KT extinction event. But if we go by the broader stem group definition unless we want to consider every dinosaur, pterosaur, and avemetatarsialian archosaur a "bird" you have to find some sort of arbitrary distinction between what is and isn't a bird , beyond the crown group.
Personally I think that this should probably just be the clade that includes crown birds and all other dinosaurs that share a common, volant(flight/gliding capable) ancestor. Like that's the defining characteristic of a bird, that sets them apart from all other animals; the ancestral ability to fly using feathered wings.
Basically I think velociraptor should be considered a bird.

And continuing on the "post my art, actually": complaining about memes in Paleontography.
I'm not talking about something like this, which is cool. I'm talking about features that are propagated across paleontography for no good reason, and in this case, how ridiculous they look on modern animals.
(since we have no ability to tell what color or pattern most extinct animals were, I have given the reconstructions their life colors)
Meme 1: everyone seems to reconstruct feathered dinosaurs with a rather useless "pseudobeak" or even a fully naked or scaled face. There is no evidence for this at least for most species, and as you can see, modern predatory mammals (Canis lupus and Panthera tigris here) look ridiculous when given such a treatment.
Interestingly, there is one group of mammals with such a bare face: primates like baboons. HMM.
Meme 2: slavishly reconstructing animals based on their distant relatives. So this is Equus przewalskii reconstructed with the integument of a rhinoceros instead of their short fur coat. Now, of course, this is due to absence of alternative evidence, but I've seen people insist that all ceratopsians be reconstructed after either Triceratops or Psitaccosaurus, regardless of size or habitat. I find series of ceratopsians that all have Psitaccosaurus's tail spines and Triceratops's scutes irritating.
Meme 3: "This Macropus rufus has been reconstructed accurately with scaly integument, since all fur impressions are known from Eutherans, and marsupials were probably too primitive to have them."
Primitive mammals manage to dodge this trap, of course—there's usually a variety of constructions of mammal-like reptiles using scales, fur, hide, or a combination thereof, but dinosaurs always got scales unless they were theropods until Tianyulong and Kulindadromeus... despite small size and endothermic anatomy suggesting integument.
Next up, if I ever do more, is going to be my take on Tianyulong and Psitaccosaurus, or perhaps a redtailed hawk with scales all over their body.
