Extant Hemipristis elongata shark tooth from Atlantic ocean?
Dino9876 posted a topic in Questions & Answers
Hello, I have another tooth from my collection that I am not sure about. For me it first looked like a very clear case. The shape of the tooth clearly indicates the snaggletooth shark (Hemipristis elongata). I was 100% certain with the ID, the teeth are almost unmistakable. The only flaw: The tooth was found on the coastline of the Atlantic between Florida and Virginia (unfortunately I don't know the exact location). Over 10.000km far from the distribution area of this shark. My question to you: is my ID correct? And if so, how can something like this happen? I hope you can help me. The tooth measures 15mm in leght. Best regards from Germany and stay healthy in this time!- 7 replies

Sharks belong to the superorder Selachimorpha in the subclass Elasmobranchii, in the class Chondrichthyes. Listed below are the nine orders of extant sharks. I really believe that to be able to successfully understand and identify fossil shark teeth you need to understand and be very familiar with extant shark teeth. As a result, I’m in the process of acquiring a good number of extant shark jaws which I intend to study and photograph. I’m not trying to acquire the very large grade A type specimens (Wow they cost a lot) but study quality specimens. If you clique on a link you will see a TFF post on the jaw of the indicated species. As I add new jaw posts, I’ll update this list. I’ve included this structure so you can see where each species fits within the Chondrichthyes hierarchy. I hope to be able to add several new jaws per month. These extant jaws can also be found on my family fossil website http://phatfossils.com/ under Extant-References.
