In the eary Createaous ichthyosaurs continue to be as diverse as they were in the Late Jurassic. Four genera Caypullisaurus, Maiaspondylus, Athabascasasus and Platypterygius. Platypterygius longmani was an ichthyosaur, a dolphin-like marine reptile that roamed the Eromanga Sea of inland Australia during the Early Cretaceous. This large ichthyosaur would have been a top marine predator, feeding on fish and cephalopods. Ichthyosaurs had the largest eyes of any vertebrate, and keen eyesight would have helped Platypterygius to spot prey in dark, cold waters.
The seem to speciaized for preying on fish and squid in the open Oceans.
