For here's Haplophrentis carinatus from Stanley Glacier (#BurgessShale) with feeding tentacles preserved. This was a key that provided a link between and and it may have a cameo in my upcoming NPGS talk...

For here's some of the newly-named azhdarchid Cryodrakon made several years before the specimen was named. The two older images here are from 2009 (a whole decade ago!) and the newer, prettier version is from 2016.

Spent October "break" getting caught up on research. Here's Krapina 3, different virtual reconstructions of its endocast put its size at around 1275 cc

Subject of my next scene: one of my favorite Cenozoic mammals, the Late Eocene brontotheriid Embolotherium. Wasn't planning on this color scheme, but I kinda love it

During our meeting, the faculty briefly discussed speculative evolution & mentioned the speculative evolutionary routes that and other animals would have underwent as seen in the illustrations by Dougal Dixon.

Looking back on some of my old this and reminding myself that while I have a lot to learn in the fundamentals department, my iridescence game is not to be trifled with 😈🦚🖍️ Can't wait to get that Caihong fully rendered

Some happy news: my Doggerland walrus has snuck into LTTAII (we had some blank pages that needed content). The challenge now is to explain this complex scene, and why it's in the book, in a caption no longer than this tweet.

fourth is KNM-ER 17400. This is a skull, eroded on the front, that has been attributed to Paranthropus boisei. The individual lived around 1.8 million years ago. At around 390 ml, its brain is one of the smallest in the hominin fossil record.

Earliest were different from modern, huge bone-crackers like Crocuta. Protictitherium, from the Miocene of Batallones, was no larger than a jackal and had a varied diet including carrion. From fossils to sketches to full reconstruction

Today's focus is the La Brea Tar Pits in Los Angeles, one of the richest fossil sites in the entire world. More than 3.5m specimens from over 600 species have been found here! 😮 So, why did so many animals meet their demise at & what can we learn from them?
