Description
Original diagnose after Leidy (1877) p. 249: Figures 8 and 9 of Plate xxxiv represent a tooth, twice the natural size, from the Ashley phosphate beds, ,which may be the symphysial tooth of a Shark, or perhaps the tooth of a Ray. The crown is a narrow curved cone with a laterally expanded base, and twice the length on its external face that it is on the inner face. The point curves inward •and posteriorly. The outline of the base in front is convex. The outer lateral border presents a single denticle a short distance from the summit. The root extends below the crown with a prominent obtuse convex border, and projects backward in a broad trilobate base, as seen in figure 9. Length of the tooth in front, 4 3/4 lines; breadth 3 1/2 lines. Length of the crown in front, 3 1/2 lines. Height of base of root posteriorly, 3 3/4 lines; breadth, 3 1/4 lines.
