Hey Gang,
So yesterday I was going thru some Plio-Pleistocene shell bed debris in Sarasota Cnty, Florida and I ran across this tiny unknown. I was looking for darker items that stand out on the white sand/shell fragments, picking up very tiny shark teeth fragments and other small phosphatic pebbles and other small black unknowns. Its all of .5cm across, an irregular sphere shape, has small inconsistent pitting/dimpling over most of its surface. Note: I could have caused some of the pitting as I dropped it during cleaning on the concrete flr in my garage and it bounced around like a superball and ricocheted all over creation and somehow I still managed to find it). It also has a small distinct irregular depression on one side which you can see in the last photo.
I thought maybe pearl but I just dont know anything about them and it seemed unlikely so maybe its even a manmade something or simply a really worn phosphate pebble. It has that deep black/dark gray color of dugong/whale bone--could it be a rounded polished bone fragment? The irregular pattern of the small dents/pitting is intriguing.
Any thoughts are appreciated.
Regards, Chris
