Hello, First time ever posting here and I am looking for some fossil ID's for the three attached fossils. The first one below is 70x65x10mm; middle is 100x90x60mm, and the bottom is 100x90x40mm. Unfortunately, I can't say much about location. These come from a relative who passed away who had a degree in earth science, and got that degree in 1960. He did a lot of traveling and collecting of fossils in the western USA, although he was raised and went to college in western PA USA. Not sure how useful that is, but that's all I have.
Thank you in advance for any help!
