A New Genus and Species of Carnivorous Dinosaur from the Lower Cretaceous Kwanmon Group, Northern Kyushu

Abstract

A large tooth of a carnivorous dinosaur is reported as the first record from the Lower Cretaceous Kwanmon Group, northern Kyushu, Japan. The characters of the tooth, such as fine serration, rugose longitudinal surface ornamentation and compressed shape, are significant, and a new genus and species, Wakinosaurus satoi is proposed. The genus is allocated to the Family Megalosauridae tentatively.
