九州の下部白亜系関門層群からの新種肉食恐竜化石

抄録

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.
