Hi, this fossil i believe was found on Mt. Snowden in Wales, it may be a long shot to identify since its not very unique looking, but worth a shot
Definitely some kind of vertebrae, there is another on the other side of the stone that I will attach in the replies, however that one seems to be a deep indent rather than sticking out like the big one, so if anyone could shed some light on that i would be grateful.
Thanks!
