Kaprosuchus (also know as the boarcroc) is an extinct crocodyliform discovered in the Sahara near the Nile. They were terrestrial hunters (not aquatic like modern crocs) present during the Upper Cretaceous (95 MA) and were able to gallop at high speeds on land.

Please note Logan is NOT a dinosaur, but rather an archosaur! All dinosaurs are archosaurs, but archosaurs are not all dinosaurs! Archosaurs include pseudosuchia (croc relatives), dinos, and pterosaurs (which are NOT dinosaurs and it will never cease to annoy me when they're called dinos).
