Thanks to Ceri Thomas for the very cool Anisodon reconstruction. Check out more of Ceri's paleoart at / alphynix and nixillustration...
And thanks as always to Nobumichi Tamura for allowing us to use his wonderful paleoart: spinops.blogspo...
Finally, thanks to Dmitry Bogdanov, Roman Uchytel, Ryan Somma and Julio Lacerda for their excellent images as well.
