Tooth shaped - fossil or possibly just a stone?

[Mcgon79]

Is this a fossil or just two different rock types. One softer that has worn in the shape of a tooth?

I found it in a river in Wicklow in Ireland.

Any comments appreciated.

That sure does look amazing similar to a tooth, but I'm afraid it's exactly what you're thinking. 2 layers of stone abraded by nature. There's absolutely no sign of enamel on this to be seen. Just grains. Nevertheless, I'd keep it as a conversation piece.

That's one peculiar looking rock!  But I'm afraid @Ludwigia is right, and this is just a really strange coincidence. No bone-texture or enamel to be seen, so I'd say two different types of sandstone stuck together.

boy Mother Nature sure does like to be tricky!! Great to keep as a "pseudofossil".

Thanks for your replies everyone. I'm disappointed but I've learned some things.

I'll keep hunting.

Wow! That is one cool rock. Not a tooth, but I think it's a keeper. Definitely one of the coolest rocks I've ever seen -- and that's 60 years of rocks we're talking about!

+1 even though it’s not a tooth I’d keep it in my collection just because it is so cool!

Thanks for the cool comments guys. The rock is definitely unusual and I'll certainly keep it in my collection as the fossil that never was.

Geology is cool too. Hehe.
