New to the internet for My take on a Gastornis family for LTTAII. I've posted various WIPs of this over the years, but not the full, final version. You get to decide what happens to the chap in the lower-left corner: there's more than birds in this image.

By gum, it's 19:35 on time to call it a day. Here's some 2016 of the Cretaceous mammal Spinolestes to sign off for the weekend with. The fluffy tails are speculative, but the other soft-tissues are evidenced by fossil data.

Have spent the afternoon with ammonites, so here's some of biggest one of all for Parapuzosia. A small mosasaur is being scavenged (we don't know what the ecology of Parapuzosia was, but lots of ammonites are thought to be nektobenthic scavengers).

Paleontologists discovered 3 extinct species in Orange County, CA, one of which has “semi-tusks”. This contributes to our understanding of tusk evolution.

With the conjunction of and Echinochimaera, a stem-holocephalan from the late-Mississippian Bear Gulch limestone.

Very well-endowed in the spine department, Echinochimaera is just a slice of the group's huge Carboniferous diversity in.

Some new-to-the-internet for everybody's favourite tiny-headed synapsid, Cotylorhynchus romeri. Yes, heads that small really went on bodies that big. You could get away with this sort of thing in the Early Permian.

A fun comparison for Pterodactylus restored by Jean Hermann in 1800 vs. Pterodactylus restored by me, 220 years later. Hermann's pterosaur is the oldest known 'legit' piece of palaeoart - a fossil-based life reconstruction based on science, not mythology.

Some new for my take on Yutyrannus published in entirety for the first time this week. It was created for LTTAII, but that's coming out soon enough to let the covers slip a little on the art. A short thread about this image...

I've had a marine-filled couple of days (so many whales and sea birds!), so here's Jurassic equivalent for Rhomaleosaurus, juvenile Stenopterygius, Parapsicephalus and many inverts. Composition is exactly how you see large marine vertebrates in real life.

Here’s a Kansas discovery for Hesperornis, a large from the Late Cretaceous. It had very small wings, but made up for it with its powerful legs and sharp teeth that it used to catch fish.

For of Protoceratops. This animal is often said to be the inspiration for griffins: though a popular idea, it's not compelling on account of ignoring a lot of historic, anatomical and geographic data. For more details, check out: https://t.co/xTq4pElHVL
