Gastropoda fossil.

It sounds like you wouldn't benefit from something that complex as you aren't interested in the chemical range of formation for the individual types of the amphibole series minerals present etc... but the below should help you differentiate. You best bet for recognisable fossils are sandstone, limestone, mudstone, shale, and chalk. Thanks a lot!
