Hi, Eric,
I am having difficulty identifying the submission form these images. If possible, please take pictures of the examples in outdoor light. I am also unable to tell if these are possible fossils in a matrix or separated from the stone where they were discovered.

I am not certain, but it is possible that this is not a fossil but is possibly Chalcedony. It is an aggregate of cryptocrystalline or microcrystalline silica.

Thank you,
Amber
