Ichthyosaur find may challenge notions about prehistoric migrations

Two Stanford geologists recently had the good fortune to be in the right place at the right time to make the kind of discovery that fossil hunters only dream of: They uncovered the bones of a large aquatic reptile known as an ichthyosaur near the southernmost tip of Chilean Patagonia -- a find that may have scientists rethinking theories about ancient migration routes and the demise of a supercontinent.

"Ichthyosaurs were aquatic reptiles that lived between 250 million and 90 million years ago. They were shaped roughly like dolphins with long, thin noses and disproportionately large eyes. The biggest ichthyosaurs were more than 45 feet long and fed on squid, fish and other marine animals."

The pics of these guys are pretty fierce if you see any artist renditions of them....
