Placochelys (from Greek : plax, plakos, "plate" and Greek : chelys, "tortoise") [1] is an extinct genus of placodont reptiles erected by Otto Jaekel in 1902.
Fossils of Placochelys dates back to the Triassic period (age range: 221.5 to 205.6 million years ago). They have been found in Germany, Austria, Hungary and Italy. [2]
This genus includes only one species:
Placochelys looked remarkably similar to a sea turtle, and grew to about 90 centimetres (3.0 ft) in length. It had a flat turtle-like carapace covered with knobbly plates, and a compact triangular skull. Its beaked skull had powerful muscles. It had only two pairs of palatal teeth, a large posterior pair, and a small rostral pair. The specialized broad teeth on the palate, were most likely used for crushing shellfish and hard-shelled prey. Its limbs were paddle-shaped for swimming, although, unlike modern sea turtles, they still had discernable toes, and it also had a short tail. [3]
