What their names are is a mystery to me. So if there are any fossil detectives out there and you can solve this naming enigma... let me know. Mulţumesc!
Thanks to Stanca for the pictures.

Fossils have not been prepped yet so I am hoping for better detail once they are cleaned.

I make no claims as to being a mineral expert but I believe these specimens are fluorite mixed with calcite or some other mineral (dolomite?). They were found with Cyclonema sp. snail fossils in Franklin County, Kentucky. The layer should be the Lexington Limestone of the Ordovician Period.
The majority of the fluorite is yellow but one has a small section of purple. I find it unique as typically think of the fluorite areas of the state of Kentucky to the western part near southern Illinois.
Mindat.org lists fluorite, calcite, and dolomite as all being found in Franklin County, Kentucky.

This interesting fossil is some sort of clam preserved by carbonaceous film. It was found in the Lexington Limestone of Franklin County, Kentucky. The name might be a Psiloconcha sp. If you look at the picture of the matrix plate, it was fossilized in place with a number of other sea creatures. In addition, a brachiopod imprint appears in the matrix as well. Also the clam might have some calcite crystals at one end of it.
Thanks to Lawrence for these fossils.
