RescueMJ Posted March 17, 2021 Share Posted March 17, 2021 Unusual Shark tooth. Inland, Venice, FL. Pleistocene material is common. Heavy serrations both sides. Bulbous protrusion. Shaped like a lower tooth but serrations on both sides. Tooth is 31mm long and 20mm wide. Is this an odd shaped Hemi upper or from a different species. -Regards, Michael Link to comment Share on other sites More sharing options...
Thomas.Dodson Posted March 17, 2021 Share Posted March 17, 2021 Looks like a Hemi. The anterior-most upper teeth (A1 and A2) in Hemipristis get straight like this. Link to comment Share on other sites More sharing options...
RescueMJ Posted March 17, 2021 Author Share Posted March 17, 2021 Thanks, I didn’t have a reference of this tooth in my collection. Thought it was an upper Hemi, but the “bulbous protuberance “ threw me off. - Michael Link to comment Share on other sites More sharing options...
Coco Posted March 17, 2021 Share Posted March 17, 2021 Hi, Your tooth is normal, in this species (Hemipristis serra) they have different shapes according to their position (which isn't the case for all sharks). Here it is a lower lateral tooth. On the recent species Hemipristis elongatus, these teeth are less serrated on one side.

Shellseeker Posted March 17, 2021 Share Posted March 17, 2021 One of my very first "outstanding" finds from the Peace River when I started over a decade ago. Thanks for bringing back the memory. 2 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...

Coco Coco, I think it was very much a part of "hooking" me on this fossil hobby. At the time , it was hard to believe that I could find something so attractive from millions of years ago.
