Placodontia

Placodonts ("tablet teeth") are an extinct order of marine reptiles that lived during the Triassic period, becoming extinct at the end of the period. They were part of Sauropterygia, the group that includes plesiosaurs. Placodonts were generally between 1 and 2 m (3 ft 3 in and 6 ft 7 in) in length, with some of the largest measuring 3 m (9.8 ft) long.
