Odontochelys semitestacea (meaning "toothed turtle with a half-shell") is a Late Triassic relative of turtles. Before Pappochelys was discovered and Eunotosaurus was redescribed, Odontochelys was considered the oldest undisputed member of Pantestudines (i.e. a stem-turtle). It is the only known species in the genus Odontochelys and the family Odontochelyidae.
