A couple of weeks ago I stopped by Blue Banks, just north of Purse State Park MD. The Paleocene Aquia Formation is exposed there, and teeth and bones of a variety of species erode from the exposures and accumulate in gravel along the shore. Unfortunately the Potomac River was in flood stage, so the gravel along the shore was submerged despite the low tide. A driving rain storm did not help matters. I scooped gravel and passed it through a couple of screens, and recovered a handful of the usual small sand tigers and ray teeth, before calling it quits after an hour or so. The following was the largest tooth I collected by some margin. I don't see anything like it on Elasmo.com. There are no serrations and no cusps. Any suggestions for an ID would be most welcome.
