Sarcosuchus & Ornithopoda dinosaurs

A pair of four-foot-long ornithischian dinosaurs of the order Ornithopoda give wide berth to a 40-foot-long, 10-ton crocodyliform of the genus Sarcosuchus 110 million years ago in what is today Africa. A distant relative of the crocodile,  Sarcosuchus was one of the largest crocodile-like reptiles that ever lived, nearly twice as long as today's saltwater crocodile.
