Ophthalmosaurus natans

Baptanodon is an ichthyosaur of the Late Jurassic period, named for its supposed lack of teeth. It had a graceful 3.5 m (11 ft) long dolphin-shaped body, and its jaws were well adapted for catching squid. Major fossil finds of this genus have been recorded in North America. The type species, Sauranodon natans, was originally included under Sauranodon in 1879, but this name was preoccupied.
