Hi, Thank you all so much for your vast expertise. I have been a novice member for some months and have learnt so much from browsing around this forum. It is fascinating and l can happily spend hours here. I only have a few fossils , all common and easily identified. But l recently aquired this tooth which with the help of information on this forum l am tentatively labelling as a Sperm Whale tooth (Pygmy ?) It has horizontal banding and a hollow base which l think are characteristics? Unfortunately l have no information asto its region of origin. But it does have an old inventory (?) number on it, so it has been in someones collection for a while. At first glance it looks like there is a horrible repair/ patch on its tip. But this does not seem to be the case, just feeding damage wearing the tooth down to the underlying enamel area ? If l understand this correctly the cementum is on the outside of whale teeth and the enamel only shows through on the tip where it is worn away with feeding ? Any information as to age ,species etc would be gratefully received. (even if it turns out to be a croc tooth !) Thanks so much Sue

I'm not even sure what these are, but I was kayaking near Cherry Point and found these while walking on a sandbar. They seemed really unique so I tried to look them up and haven't found anything.
