Ogmodirus is an extinct genus of plesiosaur found in the Cenomanian-Turonian (Late Cretaceous) Greenhorn Limestone of Kansas.[http://www.oceansofkansas.com/Will-Moodie13.html Ogmodirus martini] from Oceans of Kansas The type species, O. martini, was named by Samuel Wendell Williston and Roy Lee Moodie in 1913.Williston, S. W. and Moodie, R. L. (1913). New plesiosaurian genus from the Cretaceous of Nebraska. Bulletin of the Geological Society of America 24: 120-121.
Discovery and naming
The holotype, KUVP 441, consists of a pelvic girdle, limb elements, and more than fifty cervical (neck) vertebrae from a juvenile discovered in Cloud County, Kansas by C. Boyce in 1909. KUVP 441 was named as Ogmodirus martini by Williston & Moodie (1913) and the specific name was emended to martinii by Moodie (1916), but the original name takes precedence. The holotype was described in detail by Williston & Moodie (1917).S. W. Williston and R. L. Moodie. (1917). Ogmodirus martinii, a new plesiosaur from the Cretaceous of Wyoming. The University of Kansas Science Bulletin 10(2):61-73
A second species, Ogmodirus ischiadicus (based on specimen KUVP 434), was initially placed within its own genus, Thalassiosaurus, and has since been referred to Styxosaurus. S. W. Williston. (1903). North American plesiosaurs, part 1. Geological Series Field Museum of Natural History 3(1):1-77 It was placed in Ogmodirus by Williston & Moodie (1917).
Classification
According to Welles (1962),S. P. Welles. (1962). A new species of elasmosaur from the Aptian of Colombia and a review of the Cretaceous plesiosaurs. University of California Publications in Geological Sciences 44(1):1-96 Ogmodirus martini may be member of the Elasmosauridae, a group of marine animals related to Elasmosaurus, but the condition of the fossils discovered to date means the genus is dubious beyond Plesiosauria. Sepkoski (2002) assigned Ogmodirus to the Plesiosauria.Sepkoski, J.J. (2002). A compendium of fossil marine animal genera. Bulletins of American Paleontology 363:1-560.
