👍

It does resemble a shark tooth

Looks like a type of ammonite

I can send some more in a bit

I don’t think it is, because I’ve just read it lived in Northern Africa but not England

I’m going to post something else and it would be great to have your opinion on that, please?

Thanks for the suggestion

It all depends on the sediment it mixes with

Maybe?

That would have originated from the first era in the history of complex life (542 million years ago to 488 million years ago)

It would date back to the Cambrian era

Your fossil is very, very ancient

It doesn’t look long enough for a spinosaur tooth and maybe more of a carcharodontosaurus tooth

Dip it in hot and soapy water and then if any sediment isn’t coming off use an old toothbrush to clean it up and brush it up

My best bet it’s a cave Hyena tooth
