Otodus was a type of extinct mackerel shark, of which modern Great White sharks are a part. It grew to be considerably larger than modern predatory sharks, and was likely the apex marine predator of its day. Our tooth is still partially in matrix, but nicely shows the curved edge that this species is known for. We are also fortunate to have a fossilized Otodus vertebra.
The primary problem with reconstructing prehistoric sharks is that their skeletons are cartilagenous, as opposed to bony. Cartilage tends not to fossilize well at all, unless the cartilage ossified somewhat later in the animal’s life. We are lucky that our particular shark lived long enough for this to happen. There is still a small amount of matrix on this vertebra, but it is harder for me to remove than the matrix from the Zarafasaura vertebra was. One of my Zoology students worked on it for a bit, and even he had difficulty dislodging much more than I did.
Otodus sharks probably behaved much like modern Great Whites, and would have fed on animals such as large fish, other sharks, and primitive whales. Many fossilized whale bones are found with gashes and punctures that line up with shark teeth. Many of these marks are on the undersides of the bone, indicating that the shark probably struck from beneath. This behavior pattern is also seen in modern sharks, especially Great Whites.
