, AMNH 8477, has been recovered from the Clambank Hollow locality. The dentary does not seem to be so curved in the medial direction as some of the later Lance specimens. Anteriorly the jaw is broken, but as in the Lance specimens the teeth reach close to the ventral border. The pleurodont teeth are in a tooth border which is wide anteriorly and narrows considerably posteriorly. Externally, there is a long, narrow groove leading into a foramen at the position of the third or fourth tooth from the posterior.
