Hi,
These were long lost fossils that I happened upon the other day. I collected them in 1981 somewhere north of Atlanta in Georgia. At the time, I thought they might be Trilobites from the Cambrian, but now am now I have no idea what they are or even if they are from the Cambrian.
Sorry, I can't give a more definitive location, formation or time period. The rock is very soft, almost chalk-like. As I recall, they were in talus from outside a quarry.
Any I.D. will be gratefully appreciated.
