A number of unknowns

I have a number of unknowns as well as a couple questions. Is Aurora, Yorktown formation or Pungo? What is the age of Aurora? The scale is a U.S quarter, about 1 inch or 2.54 cm

 

Shells from aurora:

My guess for the ammonites at the bottom would be Cleoniceras sp. Cretaceous, Madagascar.

Ark clam is the common name for a family of small to large-sized saltwater clams or marine bivalve molluscs in the family Arcidae. Ark clams vary both in shape and size. They number about 200 species worldwide

Maybe Phacops? A picture for comparison :

No it has those things coming off the side of its head. I was thinking gerastos?

The phosphate they are mining at Lee Creek is the mid Miocene Pungo River Formation but the upper layers of the mine will fall into the shovels and mix with the other material. Pliocene Yorktown Formation and Pleistocene James City and other Pleistocene will be mixed in. The shells are mostly Pleistocene because the aragonite in the Pungo River and Yorktown is leached away at this location.
