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.
