Three unidentified fossils -- rhacolepis? orthoceras? some kind of bivalve?

Description

Lot of 3 fossils
These are some fossils that a family member gathered here and there.
They look like some type of bivalve? and an orthoceras? (both about 2 inches long), and a 7-inch possible rhacolepis?
Total weight 2 1/2 pounds.
Since I have zero knowledge on this subject (I simply googled "common fossils" and "fossil fish" to learn the words orthoceras and rhacolepis), I do not wish to make any claims about these fossils. I just want to rehome them for a reasonable price.
I will ship using priority mail flat rate box with lots of cushioning so that they will arrive safely.
Thank you for visiting my listing!
