Please help wit ID - tooth or tusk and if not elephant/mammoth, who did it belong to?

[hahnewald]

Hello to All. Any help and input on a correct ID will be awesome. Spotted on the high tide line amongst shell and other debris. The location has seen significant fluctuations in sea levels and has produced Pleistocene material, such as horse teeth, mammoth teeth, even Rhino and Hippo teeth but also Miocene fossils like Megalodon teeth, cetacean teeth and inner ear periotic bones as well as bulla, Great White and Mako shark teeth, just to name a few. All washed ashore by tidal movement. The specimen in question was photographed alongside a horse incisor and a mammoth tooth fragment. Its cross section seems to show cross hatching patterns of ivory but I fail to see how it can be part of elephant or mammoth tusk. It measures 5 cm in length and 1,1 cm at its widest point. Would love to hear from the TFF experts. Thanks a lot.

Out of all the teeth and ivory you listed I would say it looks more like a Rhino tooth, but I am not an expert on ivory or teeth.

Hi, thank you @fossilhunter21 for your initial response. The specimen in question is the brown piece in the middle. For reference some clearer photos of its cross section.

Hmm that is very hard to ID especially since so much of it is missing, but maybe @Fossildude19 can help

It is Mastodon (or Gomphothere) based on the age of the deposit.

Rhino and Mastodon are similar but the width of the enamel is only 1/2 in Rhino versus Mastodon
