Is This A Shark Tooth Calcified In Something, Or Just A Rock?

I was at the beach during low tide when I went in the shallow water and was looking for various stones when I came across this object. I’m not sure if it is a shark tooth encased in a rock of some sort, or just a rock? I think it is only a rock but the contours of this object could signal that a fossil is inside. Does anyone know what this could be? Thank you everyone.

This is not a fossil, but a weathered stone. However, it is better to have picked up a rock than to have missed a fossil!

It's a rock, but definitely it looks very tooth-ey

It's a safe bet that the larger end (would be root) is more resistant to erosion.

Yep. Just a rock, weathered into a suggestive shape. Still a cool little find, and something I may have picked up for further investigation.
