Shark tooth, Striatolamia GLIKMAN, 19642 As noted above, Striatolamia was not included as an odontaspid in C&N. Cunningham (2000) reconstructed a Carcharias-like tooth-set based on several hundred Striatolamia macrota teeth from the Nanjemoy Fm (Ypresian, Virginia). In the intervening years, increasing the sample to thousands of teeth only served to re-enforce these earlier conclusions (unpublished). The senior webpage author had also collected this Potapaco Mbr, Nanjemoy Fm locale and attempted to repeat the Cunningham (2000) conclusions for this webpage. Using his 'horizontal dentition' methodology, the results were successfully duplicated. The similarity of the tooth-set design (lateral file-position counts and tooth-design) strongly supports an odontaspid dentition of the Carcharias-type.
