I was given this microfossil, which has no provenance whatsoever. Any suggestions would be most helpful.

Hi! I’m still trying to identify one fossil from a particular unit of Pleistocene/Early Holocene lacustrine silt from my hometown of Saskatoon, but I figured I would look away from it for a bit to try and identify another fossil from the same unit I’ve been unable to classify. I have two specimens, both apparently of the same species. They are both approximately 0.5 millimetres across. They are perfectly circular, with lines radiating from the centre and rings of alternating colours (possibly representing growth lines). One specimen is photographed dorsally, showing its circular shape, the other in profile, showing its umbrella-like, protruding outline. All photos are taken through a microscope with my best camera currently available, an iPhone! My main areas of middling expertise are arthropod and vertebrate fossils, so I have no idea what this is! I have briefly studied fossil foraminifera and diatoms in the past, but it looks like nothing I’ve seen in those areas as well. It reminded me of a small limpet, some type of seed or spore, or perhaps even a strange fish scale, but I have no formal suggestions. I’d highly appreciate any help! I will try to supply any additional information you may need. Thank you!

Can please someone help me? I found this fossil from an middle ordovician place. Could it be a horncoral or a foram with a spiralform? The specimen is about 2 cm in diameter, some parts hidden in the stone. Any help very appreciated.

Hello all, I believe that one of these is a foraminifera, not too sure if that tiny bivalve and snail would be considered one or not. Anyone have any ideal what period these may be from? Was digging some old bivalves and gastropods out of some sandstone and came across a boulder that had hundreds of microfossils mixed in it's debris. The size range from what you see here to less than 0.50mm. Some if this stuff is really cool looking.

My specimens of this species are 2-3mm in diameter, and the thickness in the center is about 2/3 of the diameter. Thickness on the edge goes down to about 0.1mm. .
