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. In this initial framework, vibrant orange indicates times in earth history to commonly observe the item of interest; paler orange indicates times in earth history to less commonly observe the item of interest. White indicates very little to no practical probability of observing the item of interest. Please keep in mind that the listed indicators are things like "conspicuous horn corals," purposefully declining to address rare encounters with groups of low preservation potential etc. Got additions/amendments? Toss them in the comments below! Thank you for your insight and assistance.....

Greetings, all! I've been on the forum for a bit but haven't introduced myself yet. I'm currently a paleontology student, and I'm specializing in paleozoic vertebrates. I'm especially interested in Mississippian chondrichthyan communities and diversity, but I'm still interested in most other fossil taxa from most time periods as well. My favorite fossil hunts have been in the Hell Creek Fm. of North & South Dakota, and I really want to hunt the Pierre Shale sometime soon. I also would like to hunt the Cleveland Shale for placoderm material. Unfortunately for me, the Dayton area contains outcrops of exclusively Upper Ordovician (Cincinattian) and Silurian bedrock; these rock units contain no vertebrate remains except for conodont elements. Even so, I still hunt local outcrops for fossils and have an abundance of brachiopods and horn corals in my fossil collection as well as a few other treasures. (If you want to trade, then let me know!) If you would like help IDing Mississippian vertebrate remains, desire tips for hunting the Dayton area, or want to just geek out about fossils, then send me a message or tag me in a post. -Elasmohunter
