''Besanosaurus'' (meaning "Besano (N. Italy ) lizard") is a genus of large ichthyosaur (a marine reptile, not a dinosaur) that lived during the middle Triassic period,〔 approximately 235 million years ago. This marine reptile came from the family Shastasauridae and was named by Dal Sasso and Pinna in 1996.〔 The type of species is ''Besanosaurus leptorhynchus'' meaning "long-beaked reptile from Besano."〔 ==Description== ''Besanosaurus'' was a marine reptile nearly 6 meters in length and had a similar shape to dolphins. It had a thin snout, fairly small teeth, no dorsal fin, and a long and straight tail.〔 It was an eel-like swimmer with moderate speed along with rapid acceleration and good maneuvering, and lived in tropical seas, in coastal, and Caribbean-like environments. Besanosaurs were carnivorous and fed mainly on small fish, cephalopods, and marine reptiles.〔 The reptile's reproduction was ovoviviparous,〔 meaning the eggs incubated inside the body and hatched at birth.
