Ophthalmosaurus (meaning "eye lizard" in Greek) is an ichthyosaur of the Jurassic period (165–160 million years ago). Possible remains from the Cretaceous, around 145 million years ago, are also known. Named for its extremely large eyes, it had a graceful 6 metres (20 ft) long dolphin-shaped body, and its nearly toothless jaw was well adapted for catching squid. Major fossil finds of this genus have been recorded in Europe and North and South America.
