#Croctober Day 6
Heres a fun one from a research history POV.
In 1997 researchers described a snout tip under the name Baru huberi and in 2016 skull elements were given the name Ultrastenos willisi
Only last year did we recognize that both fossils belonged to a single individual

An image created by Adam Yates comparing a photo of the "complete" cranial material of Ultrastenos huberi with prior interpretations of the material. At the bottom left sits a reconstruction of Ultrastenos willisi based on the 2016 interpretation of it as a narrow-snouted animal with a circle around the skull table and an arrow pointing to the skull table of the "completed" Ultrastenos skull in the middle. The top right corner shows a reconstruction of "Baru" huberi based on pre-2024 ideas of the animal. The snout tip is encircled and an arrow points towars the snout elements of the Ultrastenos huberi fossil. This shows how both individual fossils were once interpreted vs how it actually looked like put together. The finished fossil suggests a small animal with a fairly traditional looking crocodilian snout.

For #FossilFriday, an ichnological 2-for-1 special in a body fossil: a termite nest packed with termite coprolites (feces) in an araucarian tree trunk, from the Early Cretaceous (~125 mya) of Victoria, Australia; oldest termite nest in Australia & largest wood nest from this time. 🧪🪵🪨⚒️ #ichnology

Gray to light brown fossilized (petrified) wood with interconnected spaces between the wood filled with sand-sized coprolites (fossil feces); the spaces are interpreted as a nest, and the coprolites are also attributed to termites. A few black spots on the surface are of modern marine mussels, with a marine snail and barnacle in the upper left, which were living there because the fossil tree was on a rocky marine platform on the coast of Victoria, Australia.

Cretaceous sea turtle soft tissues clarify ancestry of scale loss in chelonioids

Kear et al. describe the oldest fossil sea turtle soft tissues. These reveal the repeated evolution of scale-less skin as a hydrodynamic adaptation for oceanic lifestyles in chelonioids.

I am opposed to AI products and services because of the extra power they require... IN A CLIMATE CRISIS. I am opposed to AI results - texts and illustrations - because they've been created unethically, via theft and non-consensual use of the work of others. Share if you agree.

A Thylacoleo and Her Joey

A Thylacoleo carnifex rests with her young joey in a cave, the joey lying with its head on its mother's arm. Some light shines on the cave floor through an opening somewhere.
Thylacoleo was a carnivorous marsupial (sometimes known as the marsupial lion) that once lived in Australia.

"Pat, why do you carry that ridiculous 600mm lens on long hikes?"

Buddy, I can see mountains reflected in the eyes of a trailside pika.

Tighter crop of the same pika, focusing on its head.

An even tighter crop, focusing more on the pika's eye.

An extremely tight crop of the pika's eye, emphasizing their reflection of an early morning mountain scene.

After the Age of Dinosaurs is open this week! Here’s a 🧵 about our weird, trippy show about the weird, trippy recovery period after the end-Cretaceous extinction.

Minimalist Coryphodon model on a pedestal with embedded replicas of skull and femur. Various illuminated mammals on the wall and a Diatryma skeleton in the background.

Tree-shaped cut-out flats and overhead canopy cast forest-y shadows on the ground in museum gallery.

Sign reads "A Thriving World" in front of green-hued museum gallery. Distant mural shows a lakeside group of animals.

Illuminated illustration of bright green Titanoboa at life size.

Dromaeosaurus on display at the Royal Tyrrell Museum, Drumheller. #MuseumCore

A mounted skeleton of a small dromaeosaurid theropod dinosaur. The dino is posed as if looking up while feeding on a carcass of a Centrosaurus. A mural in the background shows the aftermath of a flood event, with debris and dead dinos strewn about. The whole scene has a subdued brownish tone, as though everything is covered in silt.
