Kcee Posted January 11, 2020 Share Posted January 11, 2020 I have shown several of these things to a number of micro-paleontologist, paleontologist, geologist and marine biologist and no one seems to know for sure what these specimen are. They were found in a sandstone boulder with bivalves fossils, they range in size from about 3mm to about 0.20mm. I'm told that they are most likely a new foraminifera species. Anyone have a clue???

caldigger Posted January 11, 2020 Share Posted January 11, 2020 I believe the first, third and fourth pics are pieces of barnacle. The rest I digress to others for ID. Link to comment Share on other sites More sharing options...

Kcee Posted January 12, 2020 Author Share Posted January 12, 2020 I thought those were barnacle plates too but there are several that look sorta like those but they come in different sizes and different configurations. Many of these have some sort of valve and some even have a bit of color, there were a number of foraminifera, sponge spicules and several microscopic bivalves and gastropods mixed in with these. There are hundreds of these things so I find it difficult to believe that they are unknown. The minimum age would be around 2.5 millions years old.
