A Squalicorax that floats?

These fossils were actually collected outside my house on the Chesapeake Bay. I was waiting for something nice to go with Croc teeth before I posted. Within about 2 weeks, I these two croc teeth and the two others shown in a previous post. The mako I found on a trip out in my boat the Squalicorax. Notice the pathological bulge on the side of the tooth.
