Baptanodon is an ichthyosaur of the Late Jurassic period (160-156 million years ago), named for its supposed lack of teeth (although teeth of this genus have since been discovered). [1] It had a graceful 3.5 m (11 ft) long dolphin-shaped body, and its jaws were well adapted for catching squid. [2] Major fossil finds of this genus have been recorded in North America. The type species, Sauranodon natans, was originally included under Sauranodon in 1879, [3] but this name was preoccupied.
Baptanodon is a replacement name for Sauranodon applied to ichthyosaur material in 1879 [3] and was moved to its own genus Baptanodon in 1880 when Sauranodon was found to be preoccupied. [4] Baptanodon was considered a junior synonym of Ophthalmosaurus by Maisch & Matzke (2000). [5] However, cladistic analyses published in the 2010s indicate that Baptanodon is not congeneric with Ophthalmosaurus icenicus. [6] [7] [8]

Fossils of Baptanodon have been found in the Oxfordian-age Sundance Formation of Wyoming, which also has yielded fossils of the cryptoclidids Tatenectes and Pantosaurus, and the pliosaurid Megalneusaurus. [4] [10]
