sharkcollector Posted January 3, 2023 Share Posted January 3, 2023 In late August, I went fossil hunting in Maryland, near the Calvert Cliffs formation, and found this tooth. I am wondering what type if shark this tooth would have come from. It measures around an inch long. Link to comment Share on other sites More sharing options...

bthemoose Posted January 4, 2023 Share Posted January 4, 2023 The photos are a bit blurry, but my best guess is Carcharodon hastalis, aka the extinct white shark that preceded the great white (Carcharodon carcharias). However, the root shape is more of a "U" than I normally associate with C. hastalis, so it's possible that I'm wrong on the ID and that this is from one of the makos (Isurus sp.) instead. Note that people often refer to C. hastalis as a "mako" because it was once classified under Isurus but that is no longer the case. Perhaps someone else can give you a more definitive answer. 1 Link to comment Share on other sites More sharing options...

Meganeura Posted January 4, 2023 Share Posted January 4, 2023 Better photos would be great - but it's very much looking C. hastalis to me. They do have roots like that depending on tooth position! Fossils? I dig it. Link to comment Share on other sites More sharing options...
