Ichthyosaurs

Ichthyosaurs reached 7m long, and were remarkably, well-engineered swimmers. As a group their species wer less varied than Sauropterygia. Ichthyosaurs bore young at sea. lchthyosaurs died out earlier than Sauropterygia, during a stormy epoch called the Turonian Stage that occurred 80 million years ago. Sauropterygia may have kept a turtle/crocodile habit of nesting ashore.
