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.

Giant Ground Sloth (Megatherium americanum) – Furry Tank

Megatherium (/mɛɡəˈθɪəriəm/ meg-ə-THEER-ee-əm; from Greek méga (μέγα) 'great' + theríon (θηρίον) 'beast') is an extinct genus of ground sloths endemic to South America that lived from the Early Pliocene through the end of the Late Pleistocene.

It is best known for the elephant-sized type species Megatherium americanum, primarily known from the Pampas, but ranging southwards to northernmost Patagonia and northwards to southern Bolivia during the late Middle Pleistocene and Late Pleistocene.

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.

Animal of the Day for November 11: Giant Anteater (Species Myrmecophaga tridactyla)

As their name suggests, Giant Anteaters mainly eat ants and termites, using their long tongues and powerful claws to get into their nests. A Giant Anteater's arms are powerful enough and claws sharp enough that they can tear down termite mounds, which are as strong as concrete. If approached, a Giant Anteater may stand straight up and T-pose, which is it telling you to kindly go elsewhere, it'd be best to comply to their request since they're one of the few animals that jaguars are afraid of.

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.

MY BABY BOY <3

Get comfy, little guy—you’ll be there for a while! Did you know that a giant anteater (Myrmecophaga tridactyla) can spend the first year of its life on its mother’s back? This mostly solitary species, which can be found in Central and South America, roams a large territory: Each individual inhabits an area of up to 22,200 acres (9,000 hectares). Fortunately for mother anteaters, piggyback rides end before babies are fully grown. An adult giant anteater can weigh up to 85 lbs (39 kg)!

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
