Help with identification. proboscidean tooth?

[Jblogo]

Hi. I found this in a river in N. Wales, UK.  Could it be related to a moumouth tooth? Or is it just a nice looking rock or tile of some sort. The top layer is 6 - 10mm thick with a lighter shade. Has anyone found anything like this? I'm curious as to what it is and how it has formed. Has it naturally erided into this?

Welcome to the Forum.

 

This is not a tooth, unfortunately. No enamel, no bone texture/roots.

Mother nature makes some pretty interesting mimics.

Indeed! A wonderful mimic but sadly not a mammoth tooth. Mammoth teeth are made of multiple plates composed of a ring of harder enamel sandwiched together with softer dentine. The flattened rings are visible on all sides of the tooth. Your mimic looks quite convincing from one side (except for the circular depressions). Were this to be a real mammoth tooth you'd see that patterning extend through to the other sides.

Welcome! I can definitely see the features that might lead you in the mammoth direction. Those lines across the top are very interesting.  But I agree it's not a mammoth tooth

 

In a mammoth tooth, the lines are formed by plates that are connected together, so you can see evidence of them on the sides, not just the top. Yours has flat sides.  

 

But it's neat.  I would pick it up too.  

 

Maybe others with more geologic knowledge can explain how it came to be shaped this way.

Difficult to say what caused this patterning, but I have seen plenty of ripple marks in North Wales.

Ah. Well wishful thinking on my behalf. I did find this specimen (pictured below) last year in exactly same part of river as my faux mammoth tooth....so thought my luck was in. I believe this might be from carboniferous period. Correct me if I'm wrong though!
