In Depth

       Acostasaurus is a genus of pliosaur that lived during the early Cretaceous period.‭ ‬Acostasaurus was a small to middle sized pliosaur that seems to have‭ ‬differed from brachauchenisine pliosaur that were otherwise common at the time and location.‭ ‬This could suggest that Acostasaurus had a different lifestyle/feeding preference to other larger pliosaurs.
