Tooth, or just interesting rock?

[Siam]

Hi everyone,

I'm hoping you can help me to identify an interesting find. It is a remarkably tooth-like 'rock' that I uncovered while digging my garden in Hampshire, UK, last year.

As you can see from the photos, it features striking, alternating stripes of white and bluish-grey around the base. As the 'tooth' narrows, the stripes abruptly stop and the texture becomes plain, though the pointed tip is different again, being white, quite sharp and crystalline in appearance.

When I found it, it was covered in a softer, sandstone-like material that I carefully removed with a wire brush to reveal the shape you see now.

Sadly, my layman's search has revealed nothing convincing so far, so I'm wondering whether it's just a tooth-shaped rock. Hence why I'm now turning to people who actually know what they're talking about for a definitive answer.

Thank you in advance for your expertise and time.

 

EDIT: Forgot to attach the all-important size photo! Now attached.

I think complex unconformity might best describe this look. A geologic phenomenon of some sort at least. It is very tooth like however.

But not a tooth. No enamel, no root texture, or actual tooth morphology.

Maybe a partial rugose coral?

I've been focused on bone and wood lately. With the adjustment made, I see what you mean.

Just returning to say a big thank you for your help in identifying my find. I guess we'll just have to keep looking!
