Is this a fossil?

Recommended Posts

Hi folks,

I found this on Killiney Beach in Dublin, Ireland. I usually find fossiliferous limestone there full of crinoids and corals and other fragments. This caught my eye but I have no idea what it is. Any thoughts anyone?

 

Sorry for the use of a 1 pence coin as a scale here, I just saw that using coins is not ideal but I am back in Ireland and the piece is at my home in London where I took the photos.

I think that this is a water worn stone that has a suggestive shape of a vertabrae.

Five for three too worn stone. But an interesting one at any rate.

Thank you all for your replies. My initial thought was that it looked a little like a vertebra but it lacks the concave centre and is more oblong than vertebrae typically are.  I knew in my heart it wasn’t a vertebra but not gonna lie I was hoping it was something exciting!

Just a heads up so you don't dismiss a vertebra accidentally, and I apologize if you already knew. Not all vertebrae are concave. So don't pass over something if it's flat or convex. Also be aware that sometimes the discs between them (intervertebral discs) are preserved.
