Hey-oh!
I found this while at GMR and I'm clueless as to what (if anything) it is. I've been though my fossil books and online but the curvature and the indention marks have me puzzled. I've not found something like this before. My luck it is a weird curious rock.. if it is, I'm just going to imagine it's a meg eye lid or something hahaha
As always, I welcome your thoughts and appreciate you all
Steve
