Catalog Number: CG-0048
A quick accidental find tonight. I stack fossil pieces all over the place. This particular piece has been out in the weather all Winter. The tip of a Petalodus Tooth blade attached to the rock. Upon examining the specimen under the microscope, it found it to be removable. With a pin vice and a ground down flattened high speed steel drill blank, I easily removed it from the limestone.
Oddly enough, there is a probably second tooth next to this one. It could be the other side of the same tooth. They are not in a natural arrangement, however. If it is indeed the same tooth, I suspect that it was broken before fossilization. The material closely resembles internal tooth matrix. There are parallel ridges that resemble the distal crown tongue of a Petalodus tooth.
Below you can see the simple anatomy of a Petalodus tooth. The distal crown tongue is the region between the cutting blade and the root.
