Pappochelys

Pappochelys (παπποχέλυς [πάππος (grandfather) + χέλυς (turtle)] meaning "grandfather turtle" in Greek) is a genus of diapsid reptile closely related to turtles. The genus contains only one species, Pappochelys rosinae, from the Middle Triassic of Germany, which was named by paleontologists Rainer Schoch [de] and Hans-Dieter Sues in 2015. The discovery of Pappochelys provides strong support for the placement of turtles within Diapsida, a hypothesis that has long been suggested by molecular data, but never previously by the fossil record. It is morphologically intermediate between the definite stem-turtle Odontochelys from the Late Triassic of China and Eunotosaurus, a reptile from the Middle Permian of South Africa.[1][2]
