The Euryapsida are a group of extinct marine
reptiles that existed at the same time as the dinosaurs, between
250 and 65 million years ago. There were four main groups of euryapsid,
the most well known of which are the ichthyosaurs and plesiosaurs.
Many were large, predatory animals, which ate fish and other reptiles.
