Many fossils of marine reptiles have recently been found in the Upper Cretaceous system of
the Japanese Islands. An isolated tooth was found in the Lower Maastrichtian section of the
Izumi Group in Awaji island, Southwestern Japan. The tooth shows characteristics of
Plesiosauroidea. This is the first Plesiosauroid from the Izumi Group, and this paper contains the
first description of Plesiosauroidea from the Maastrichtian section of the Japanese Islands.
