Need help identifying fossil shells

[Mosasaurhunter]

Hello, I found what appears to be well preserved casts of clams and sea snails and also a possible bone or coral fragment but I’m not sure what most of them are except for the sea snails which I think is Turritella sp. But I’m not sure exactly. I’m not sure exactly what formation it is either but I do know it’s most likely the Ripley formation, Providence sand formation, Clayton formation, or Nanafalia formations. So I was wondering if someone could help me identify what species these belonged to and maybe even what period there from, thanks in advance.

That’s a lot of pictures... Especially without number ! And don’t put your fingers, they eat the majority of some fossils.
