Behold the dazzling colors of an iridescent ammonite (Placenticeras intercalare)! A relative of today’s squids, this ammonite lived some 80 million years ago near what is now Alberta, Canada. This fossil’s spectacular coloration is the result of millions of years of high temperatures and pressures. As these forces acted on nacre in this ammonite’s shell, it was transformed into a gemstone known as an ammolite. Along with amber and pearl, ammolite is one of only a handful of gems made by living organisms. You can spot this rare specimen in the Louis V. Gerstner, Jr. Collections Core in the Museum’s Richard Gilder Center for Science, Education, and Innovation!

Modern mammals are the only living representatives of the synapsids, but back during the Permian there were numerous other evolutionary branches – first the pelycosaurs, and later their descendant the therapsids.
Some of the first non-mammalian therapsids were the biarmosuchians, mid-sized carnivores with a more upright posture than their pelycosaur ancestors. They had large canine teeth in their jaws and powerful bites, and some of them also developed elaborate ornamentation on their skulls, with various bony bumps and crests adorning their faces.
Pachydectes elsi was a 1.5m long (~5') biarmosuchian living in what is now South Africa during the late Permian, about 265 million years ago. Bone texture indicates its head ornamentation was covered by either tough thickened skin or a keratinous sheath, and the large bulbous bosses on the sides of its snout had a particularly rich blood supply, suggesting these structures could have been continuously growing throughout its entire life.
But despite how well-protected it looked, Pachydectes' skull was actually relatively fragile and wouldn't have been able to withstand the impact forces of using its headgear for fighting or defense. Instead it may have been mostly used for visual display – and the blood supply to the snout bosses might even have given it the ability to "blush" them if they had a soft-tissue covering.

Decided to retouch a bit of this old paleoart piece, featuring a pair of Andalgalornis taking advantage of a bushfire to hunt and scavenge for easy pickings, for no particular reason 👀
Anyways hope you like this small bit of content, it's not much but I think this is one of the best pieces I've made :>

It's the end of the dry season and the sky carries the upcoming rain on a late afternoon.

My 25 years of palaeoart chronology...
This is the last day of illustrations from the 2008 book A TIME TRAVELLER'S FIELD NOTES AND OBSERVATIONS OF DINOSAURS (by Top That!). Here is Hypacrosaurus.

Genyornis, a large, flightless "thunder bird" from Pleistocene Australia. Based on the new redescription of its skull, over a century after it was first described!

Dear good omens fanfic writers,
Proposed angel name: Othniel
This was a real life name of one of the paleontologists in the bone wars, an academic rivalry where two American paleontologists sabotaged each other’s fossil hunts! Maybe this was the name of the angel that was supposed to thwart the devils dinosaur plan?
