Short summary
We review shell bone microstructures of Adocidae and Nanhsiungchelyidae, two groups of extinct hide-necked turtles related to modern soft-shelled turtles (Trionychidae) and the pig-nosed turtle Carettochelys insculpta (Carettochelyidae). Adocids and nanhsiungchelyids both have a good fossil record in North America and Asia during the Cretaceous and Cenozoic. Our microstructural data supplement previously reported differences in external shell morphology between adocids and nanhsiungchelyids.
