Carettochelyidae
Family of turtles
From Wikipedia, the free encyclopedia
Carettochelyidae is a family of cryptodiran turtles belonging to the Trionychia. It contains only a single living species, the pig-nosed turtle (Carettochelys insculpta) native to New Guinea and Northern Australia. Stem-group carettochelyids are known from the Cretaceous of Asia,[1] with the family being widely distributed across North America, Europe, Asia and Africa during much of the Cenozoic.[2]
