pefty posted a topic in Questions & Answers

What’s bothering me is that it seems to be a marine pelecypod with aragonitic preservation. All of Ohio’s exposed rocks are either Paleozoic or Pleistocene, and with vanishingly few exceptions, Paleozoic aragonite is simply not preserved. I know there are mollusks in pleistocene marine concretions, notably from Newfoundland, but not in the sediments representing Pleistocene Ohio’s terrestrial&freshwater environments. This is a marine clam, and there was no marine

Help request! I am putting together a tool for judging rock age based on very crude, whole-rock, hand-sample observations of fossil faunas/floras -- the types of observations a child or beginner could successfully make. I view this as a complement to the very fine, species-level identifications commonly employed as index fossils for individual stages, biozones, etc. Attached is what I've got so far, but I can clearly use help with corals, mollusks, plants, vertebrates, ichnofossils, and the post-Paleozoic In the attached file, vibrant orange indicates times in earth history to com

Hi, I come here because I need some help. I just collected samples for my thesis and I´ve just realized that my samples are sandstones with many mollusca fossils. My problem here is that, I dont know how to extract the fossils without destroying them. Please help me, I need this so much, and I cant find anything about dissolving sandstones. Greetings From Monterrey, México.
