For just a reminder of how beautiful the Holotype skull of Gastonia burgei is. Best Polacanthid skull so far on planet. Yhis guy was a head pounder like a dinocephalian with pterygoid processes forming a shock absorber at front of braincase. I'm looking at you!

I have a big drop of new coming next week, but for now I'm mining the archive again for Here's Mystriosuchus steinbergeri, from 2018. This is probably one of my better paintings - I often don't like looking at older work, but I think this holds up.
