Good day everyone, I found a fossil during the summer from the Williamsville Formation, Bertie Group in Fort Erie. I have had a few people take a look at it but have not had any luck identifying it. I was wondering if anyone might have any idea:
1 cm in diameter
Almost perfectly circular
Radial rings
Can't see a verticle cross section
Does not carry on to the bottom
Photos are the only visible section
THANK YOU
