An “Ohmden’s lizard” from Early Jurassic near Ohmden, in Holzmaden, Germany. Named by paleontologist Rupert Wild in 1978.
Oligosaurus
This nomenclature (“small lizard”) is no longer recognized by scientists because they found that it described an animal that was previously given another name which is Mochlodon or Rabdodon. Named by Harry Govier Seeley in 1881.
Omeisaurus
An “Omei (Mount Emei) lizard” from Late Jurassic China. The Chinese Omei, “lofty” plus mei, “brow”; the name of a sacred mountain, Omeishan, some 100 kilometers west of Yunghsien in Sichuan Province, China. Named by Chinese paleontologist Yang Zhong-jian (also known as: Chung Chien Young) in 1939.

Onychosaurus
This nomenclature (“barbed lizard” [Greek onykh- (onyx), “claw, nail, barb”]) is no longer recognized by scientists because they found that it described an animal that was previously given another name which is Struthiosaurus or Rabdodon. Named by Franz Baron Nopcsa in 1902.
