Spectember 2023 #05: Shiny Mammal

Someone who identified themself only as "Hanna" requested a "mammal that's shiny and iridescent like some insects and spiders":

Lustrophractus hannae is a relative of modern hairy armadillos that has adapted for a semiaquatic lifestyle.

About 40cm long (~16"), its unusually shiny carapace originally evolved thanks to its ancestors' burrowing habits. Much like golden moles and some snakes, these armadillos' scutes and hairs developed microridges that reduced friction and repelled dirt particles, with the side effect of becoming strikingly iridescent – and, conveniently, also rather water repellent, enabling Lustrophractus' lineage to take up aquatic omnivorous foraging habits.

The iridescence also serves a defensive function, using a bright flash of color to startle and confuse predators.

A young 9 banded armadillo (Dasypus novemcinctus) I captured at work today. Released unharmed after brief examination. Since these guys are one of my favorite native mammals I will celebrate by posting Fun Armadillo Facts™ .

1. Nine-banded armadillos were unheard of in the United States until the late 19th century, when they crossed the Rio-Grande naturally and were introduced to Florida by humans. Their range has expanded rapidly and they now occupy much of the southern US, and are still spreading.

2. Every nine-banded armadillo you see, at one point in its life, had three identical siblings. The species almost invariably produces quadruplets!

3. They are one of the only animals other than humans to be susceptible to leprosy. With a low core temperature and a long lifespan they are perfect for the bacteria to propagate, and actually suffer it systemically rather than on mainly peripheral tissues the way humans do. You are unlikely to get leprosy from the average armadillo, however.

4. Unlike the smaller three-banded armadillo, the nine-banded cannot roll into a ball. Its methods of escape involve either a surprising rapid run, attempting to dig down to where only its carapace is exposed, or, and this is why so many are hit by cars, leaping 3+ vertical feet in order to startle predators. In the words of zefrank, this is precisely the wrong defense to survive a charging honda, regrettably.

5. They can be litter box trained much like a cat!

6.They once had gigantic prehistoric relatives including Doedicurus and Glyptotherium. Large herbivores reaching the size of small cars. I wish so badly that they remained alive so I could ride one.

I hope you enjoyed these Fun Armadillo Facts™

Kraglievichia

Kraglievichia was a genus of cingulate mammal from the Late Miocene to Early Pliocene periods. Its type species is K. paranense. Its second known species is K. carinatum. The known specimens were found in Argentina and Uruguay. Though initially described in 1883, Kraglievichia was not properly named until 1927.

Its autapomorphy from similar relatives is its distinct osteoderm ornamentation, which consists of significantly deep longitudinal depressions with a longitudinal central elevation. It is the most conspicuously ornamented pampatheriid known currently.

The known specimens of Kraglievichia consist of osteoderms, a left femur, and a well-preserved skull without any teeth. Due to their extreme similarity, Kraglievichia is regarded as the sister taxon to Scirrotherium, the genus that K. carinatum was originally assigned to. It was hypothesized that Holmesina evolved from Kraglievichia, but due to the fact there are no known immediate South American basal forms of Holmesina, this is unlikely. A third species, "K." floridanus, was named in 1976, but this was later found to be a species of Holmesina instead. 

Citations: The 1927 description seems entirely lost, at least online; if you happen to have access to this paper please let me know. 1883 description (page 66 of pdf) as Chlamydotherium; "Scirrotherium" carinatum description; "S." carinatum reassignment.

Giant armadillo

Priodontes maximus

Family Chlamyphoridae, order Cingulata, superorder Xenarthra

Also known as the tatu-canastra, tatou, ocarro, and tatú carreta.

They prefer to eat termites and ants and will often consume the population of an entire termite mound. They also sometimes eat worms, larvae, spiders, snakes, carrion, and plants.

They are the largest extant (meaning not extinct) species of armadillo, usually weighing 18.7–32.5 kg (41–72 lb). There has been a wild specimen weighing 54 kg (119 lb) and a captive one weighing 80 kg (180 lb).

They are solitary and nocturnal. They spend the daytime in burrows.

Their burrows are very large, openings average at 43 cm (17 in) wide and typically face west.

These animals have not been studied much in the wild, but it has been discovered that many animals use their burrows. Dozens of animals, including the rare short eared dog, were observed using the same armadillo burrow in one day. They’re like, the construction workers of their area.

This animal is classified as vulnerable.

Drawtober Day 30- Mummy. This thing should be my mascot. It's 2 of my favorite things combined; a silky anteater and a mummy. Anteater mummy probably has some magic powers too, like maybe they can summon an army of undead ants to do their bidding.

So the Preliminary SVP Schedule got released

For those unfamiliar, SVP = Society of Vertebrate Paleontology

usually when paleontologists say "SVP" they mean specifically the conference that SVP hosts each year, one of the biggest events for the "spends their lives studying old bones" people each year

each day has six sessions - three in the morning, three in the afternoon - and they're packed with talks. like, if you want to see talks in two different concurrent sessions, you gotta run around like a maniac

anyways

Wednesday Morning has Sauropods & Ornithischians, Early Mammals & Carnivorans, and then Fishes & Amphibians as three different sessions (all of these are groups of three going forward)

Wednesday afternoon has Dinosaur Soft Tissues, Ungulates, and Marine Reptiles

Thursday Morning has Romer Prize (fancy student talks), Birds, and Preparators' Session

Thursday afternoon has Theropod Flight Origins, Mammal Paleoecology, and Sauropsids

Friday morning has Euarchontoglires & Xenarthra, Archosaurs, and Methods & Paleohistology

Friday afternoon has Actinopterygians, Crocodylomorphs & Turtles, and Paleoecology & Paleoclimatology

Saturday morning has Theropods I, Afrotheria & Mammal Macroevolution, and Synapsids

and Saturday afternoon has Theropods II, Marine Mammals & Bats, and Squamates

The fact that Theropods get four separate focused sessions while Ornithischians and Sauropods are smushed into one is... well, I'm laughing my head off at Theropod bias right now

would you like theropods? Or more theropods? How about some THEROPODS

Okay I don't want to stay with mammals for much longer so I'm gonna go through the rest of them here

There are 22 distinct groups of mammals, I've already covered three of them (Carnivora and the even and odd-toed ungulates).

Going through the remaining 19:

There are four groups of marsupials, but that doesn't matter because Rahi-wise there is only one species, the Fusa, a kangaroo. The Kikanalo might also count, but see my ungulate post for that ramble.

There are two groups of Xenarthra (armadillos, sloths, and anteaters) but there are no rahi equivalents at all.

Monotremes (echidnas and platypuses) have no representation either.

Same with Sirenia (manatees and dugongs), Lagomorphs (rabbits), Scandentia (tree shrews), Macroscelidea (elephant shrews), Erinaceidae (hedgehogs), and Afrosoricida (tenrecs and some other miscellaneous small African mammals).

Soricomorpha (shrews and moles) has one representative, the Archives Mole.

Pachyderms likewise also only have one rep, the Hapaka.

Cetaceans only have two reps, the Razor Whale and the Stinger Whale. There is a unique whale rahi in the 2003 console game, but much like with the unique fox rahi, I don't know if I can consider it canon given the nature of the game and how drastically different many canon rahi appear in it.

Chiroptera has three reps, the Cliff Screecher, the Ice Bat, and the unnamed bat rahi from the cancelled pc game and various other 01 promo renders.

There are three primates, the Brakas, a monkey, and two apes, the Lava ape and the Spiny Stone Ape. Much like with the Kavinika, I have some questions regarding if the Spiny Stone Ape is actually an ape, given that it has a tail and frankly, kind of looks like a dinosaur, but that's a discussion for another day.

Lastly, the rodents, of which there are quite a lot. There's the Gafna, the Ice Vermin, the Kinloka, the Kuma-Nui, the Lava Rat, the Stone Rat, and the Wolf Rat from the cancelled pc game. The Kuma-Nui and Wolf Rat are especially interesting considering that the former is really fucking huge, and the later engages in some interesting specevo, being a species of one group filling in the role of a species belonging to a different group.

There, that's every mammalian analogue rahi charted

[iamthekaijuking]

apparently there used to be aquatic sloths, mountain sloths, and burrowing sloths too, as well as african-elephant-sized ones

i'm kinda underwhelmed at the sloths we have today

That semiaquatic sloth was preyed upon by macroraptorial sperm whales.

While the giant burrowing sloths could dig through solid rock and made tunnels you could stand in, many of which are still around today.

Apparently some also had osteoderms. Which technically isn’t that weird since they’re in the same group as armadillos (Xenarthra), but it still feels so weird for a mammal to have osteoderms.

But modern sloths, particularly three toed, also have incredibly weird adaptations themselves, such as:

Having curled muscles in their limbs that give them more strength (pennation)

Being very impact resistant

Sloth body temperature is usually the same as their surroundings, but if it gets too hot they actually depress their metabolism like a hibernating animal, but unlike them they don’t actually shut down organs and can do it very quickly for short periods of time

Having a four chambered stomach

Three toed sloths have 9 neck vertebrae, which is unusual because mammals can’t have more than 7 neck vertebrae because it fucks with their respiration, so three toed sloths are the only exception

It can take 50 days for a sloth to fully digest a single leaf

Three toed sloths sometimes eat as little as 17 grams of food a day, which is around 3 leaves

Sloth fur is a micro ecosystem that they cultivate thanks to weirdly craggy hair cuticles, with a species of algae and moth that only lives in their hair

Modern sloths may not look like much on the outside, but on the inside they’re positively freaky

WHAT FORM WOULD YOUR DAEMON TAKE?

xenarthra

ㅤYour daemon would take the form of a xenarthra! Those who have xenarthra daemons are introverted and truly unusual people who don't stress easily. They often have their heads in the clouds and like to go through life casually, avoiding situations that would cause conflict or too much responsibility.

specifically, a sloth

ㅤYour daemon would take the form of a sloth! You are an independent but easygoing individual with an unparalleled sense of patience. More so than others with xenartha daemons, those with sloths are calm and forgiving people, but are rather detached from others and don't mind wandering in and out of others' lives. They're not ambitious or competitive, and overall enjoy maintaining a calm and stable life.
