Somniosus insomnus💤🦈

This is an animal I'd really love to see if we get another season of Prehistoric Planet: Ice Age. It's the perfect blend of familiar and bizarre!

Getting excited... for #FossilFriday ! Our Morrison Ankylosaur monograph may be published online in a week. Hopefully, this will lead to a fix in many ankylosaur phylogenies. A dozen known Morrison ankylosaur sites spanning 4 states. Who would have think it 35 years ago?

”Bloody Mary” Nanotyrannus #sciart

Witmer with the holotype skull of Nanotyrannus (CMNH 7541) for CT scanning (June 2023). I had this same skull on loan in my Ohio University lab for study and CT scanning for over a year and, as far as I can tell, never appeared in a photo with it. I didn't my chance this time!

We'll close out this #FossilFriday with the obvious choice of Nanotyrannus. I couldn't share this CT scanning session at the time (June 2023) but can now. @jgn-paleo.bsky.social brought the holotype Cleveland skull he had on loan, and CMNH VP curator Caitlin Colleary & I joined in the fun!

Making some fresh models to sharpen my 3D skills, and what better subject to do that than our lovely brazilian Pleistocene megafauna?

Digital Drawing. A large dicynodont (Ischigualastia) is knelt on the ground, struggling to lift itself up with its forelimbs. A gash is visible on its thigh. Three small dinosaurs (Eodromaeus) observe from nearby. The sky is a pale blue - the sun has already moved below the horizon.

Why do mammals need so many face muscles 😭

Forgot to announce I have a new paper out this week! Animals that are more front-heavy have thicker, differently shaped forelimb bones to deal with the extra load. Limb bones alone may thus be useful proxies for body shape - but posture complicates things. royalsocietypublishing.org/doi/10.1098/...

Do we know the locality and horizon of the Helsinki specimen?

steller’s sea cow (Hydrodamalis giganteus)

I recently read Beasts of the Sea by Iida Turpeinen that recounts in dramatic fashion the voyage of Steller, the discovery, subsequent extinction, and the discovery of the skeleton of one and how it ended up In Helsinki. A wonderful book you should read.

Two juvenile giant moa (Dinornis robustus) run energetically along a beach, creating some splashes as they go. Small waves roll in behind them.

A skull of a brontothere mammal. It looks a bit like a rhino skull, with a long, low and robust skull and has two bony bosses over the nose.

#fossilfriday Brontothere skulls from the Eocene of the White River Badlands on display at the @alfpaleo.bsky.social museum in Claremont, CA. One of these (suspect it's the middle one) was collected by a teenage Malcolm McKenna before his career in vert paleo took off!

Qilin tungurensis (formally Palaeotragus tungurensis) have a new genus name now!
Mainly based on the holotype and paratype AMNH 26582/26583, the part of horn core based on the refered IVPP V33851.

The first cranium of Postschizotherium (Pliohyracidae, Hyracoidea) from the Lower Pleistocene of China Pliohyracidae, a group of large-bodied hyracoids, successfully colonised Eurasia during the late Cenozoic. However, their cranial morphology has remai…

This is the official publication, and it is still in press(pre-proof). But I'm very honoured to be a part of this paper and contribute my modest efforts.

And there are a large number of animals from different ecological niche coexisted here in the Longdan locality during the Early Pleistocene. Eventually, the most of the fauna disappeared with violent climate change event.
Here's a chart of the Landscape reconstruction. 6/

Combining all known informations and previous work achievements, we can see the palaeoenvironmental at the northwestern corner of the Tibetan Plateau during the Early Pleistocene is more likely a moist, mosaic of environments (including massifs, grasslands, woodlands). 5/

Although there are still more evidence is needed for verification and support, we believed that Postschizotherium is a semi-aquatic (or hydrophilic, at least) clade of Hyracoidea. This is very different from their living relatives, which is better at climbing on land. 4/

which is the first nearly complete cranium of this genus. The cranium has cylindrical orbits, protruding strongly laterally, with an elevation that surpasses the frontal surfaces. Protrude eyes are very common in semi-aquatic animals, such as the Hippopotamus 3/
