drobare Posted August 3, 2015 Share Posted August 3, 2015 I found this on Sunday. Between Calvert cliffs and Chesepeake Beach at the Matoaka Cabins area. Stuff there is usually pretty worn and this is no exception. It could be just a really worn shark's tooth of some kind, but it is rather "bulbous" in the middle, so I started thinking maybe it is something else.. Any ideas? thanks!

mrieder79 Posted August 3, 2015 Share Posted August 3, 2015 It doesn't look like a shark tooth to me. If it is a tooth, I would guess mammal, but I would rather let some more experienced members weigh in on that decision. Luck is the most important skill of a fossil diver.

Metopocetus Posted August 3, 2015 Share Posted August 3, 2015 Fish tilly bone. They are hyperostotic (abnormal or excessive bone growth) that forms on fin spines and vertebrae of fish. If you do a search for "tilly bone" on the forum or on Google you'll find similar pictures. Link to comment Share on other sites More sharing options...
