The Palatal tooth of an undetermined Lepidotes species of Kimmeridgian age, approximately 152 to 157 million years ago in the late Jurassic period. These particular teeth came from the Cymodoce Zone of the Kimmeridge Clay, in Weymouth, Dorset. Lepidotes are an extinct genus of ray-finned fish which existed during the Jurassic through to the early Cretaceous periods. These fish exploited both shallow marine and fresh water lake environments. As evidenced by these examples, their teeth are peg - like in shape, adapted to crush the robust shells of molluscan prey. These particular teeth are small 2 to 4 mm and are supplied in a small plastic bag with an information label.
