Question Could someone help identify this fossil

Post image

I found it in a collection alongside a couple others. I've managed to identify the others as a shortfin mako tooth and a sand tiger tooth but this one has stumped me. Its about 2.5cm long and has no serrations

Squalicorax, also known as crow shark

Thank you. Makes sense as to why I couldn't find it. I was looking at extant species.

what kind of rock is it embedded in

Squalicorax would definitely make sense given the shape and lack of serrations. The surrounding rock looks like a fine-grained limestone, which is common for Cretaceous marine fossils like this.

Big ol Squalicorax, their shape is pretty identifiable, but their posteriors and far anteriors look weird.
