Yet another mysterious Shark tooth.

Hello.

I am here with another unknown shark tooth.

This one I personally found. For a while I believed it to be from Hastalis, but I have doubts after searching it up. It is around 5-3 million years old.

It was also found alongside what I believe to be a Scylirhinoid vertebrae.

Haha. Just realised I uploaded the same image twice.

Mako white shark.

Thanks! I was new to fossil hunting, so didn’t know.

Is that the species name?

[Fossildude19]

No.That's the common name.

[M3gal0don_M4n]

Okay, thank you. Just clarifying, is the vertebrae from a Scylirhinoid?

[M3gal0don_M4n]

Excuse my ignorance, but is that the same as the shortfin Mako or did this particular Mako species go extinct?

Carcharodon hastalis upper antero-lateral

I agree with C. hastalis, which is not a mako.

[M3gal0don_M4n]

Thanks! I had found it on a fossil beach and my first thought was it was a hastalis but I was unsure.

Carcharodon hastalis

C hastalis was once in the genus Isurus (Mako sharks), it has been moved from there and placed in Carcharodon. Some people still (erroneously) call them a Mako - old habits I guess.
Lesser White shark is one common name I see used.
