Unnamed Eohippus relative. Equidae, 0.3 meters, unknown weight. (image is courtesy of Charles R Night, but it's in the Public Domain). I didn't want to draw Eohippus myself because I don't know how to draw mammals.
Megalosuchus Colossus. Portrayed by Alligator Mississippiensis, but made to look bigger using CGI, 11 meters, 6 metric tons. This is technically a Modern-day Slurpasaur, but less cruel because it's CGI when it fights the mosasaur and there are no glued-on horns or spikes.
