Liparoceras Posted August 28, 2019 Share Posted August 28, 2019 The first tooth is truly tiny, infact I'm not entirely convinced it's a shark tooth due to it's size. So perhaps a very small species or a juvenile? The tooth easily fits inside the 0.5cm divisions on my cutting board, and every time I take it out of its container i'm terrified of loosing it. It was found by sieving the sand at Bracklesham bay, and would have come from the Eocene Bracklesham formation. The next tooth is from the Cretaceous chalk of Bedfordshire, not sure if it's the Lower or Upper chalk formations but I assume it's from the lower chalk. It was in a pile of rocks next to a footpath, There was a short cliff nearby but i'm sure the pile was made by a farmer taking larger rocks out of the field next to the path. Anyway I have no clue as to what genus or species these are but I was hoping there would be some shark tooth experts on here who would know. Thankyou.

caldigger Posted August 28, 2019 Share Posted August 28, 2019 Your first one looks a lot like Galeorhinus sp. ( Tope shark ). 1 Link to comment Share on other sites More sharing options...
Al Dente Posted August 28, 2019 Share Posted August 28, 2019 I would guess the first tooth is either Physogaleus secundus or Scoliodon. 1 Link to comment Share on other sites More sharing options...
