Adocus is an extinct genus of aquatic turtles belonging to the family Adocidae.
Description
[edit | edit source]Species of the genus Adocus had flattened and smoothly contoured shells with horny sculptured plates. The shells could reach a length of at least 50 centimetres (1.6 ft) for North American species, some species like A. kohaku had carapace length of 60 centimetres (2.0 ft).[1] The largest species, A. kirtlandius had carapace reaching 113 centimetres (3.71 ft).[2] These large freshwater turtles had an omnivorous diet. They lived from the Late Cretaceous to the Paleocene in North America, but in Asia, they were also present during the Oligocene.
Distribution
[edit | edit source]These turtles have been found in Cretaceous to Paleogene of Canada, United States, Mongolia, China, Japan, Kazakhstan, Tajikistan, and Uzbekistan.[3]
