Description
Original diagnosis after Leidy (1877) p. 250: Figure 14, Plate xxxiv., represents a tooth nearly like those just described, but having the main point directed to one side so as to recall to mind the teeth of Galeocerdo. The specimen was obtained in the in marl of Monmouth Co., New Jersey, and was presented to the Academy by Dr. Knieskern. The inner acute border of the crown is the longer, and is convex in its course from the base of the main point. It presents seven denticles successively decreasing in size. The outer side presents two larger denticles succeeded by four minute ones. The construction of the base of the crown is like that of the preceding teeth. Length of the tooth, 3 lines; breadth, 3 1/4 lines; thickness at base, 2 3/4 lines. I have regarded the tooth as representing a species distinct from that to which the Ashley fossils pertain, under the name above given.
