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 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, low recognizability, etc. Got additions/amendments, especially for the groups mentioned above? Toss them in the comments below! Thank you..... https://docs.google.com/spreadsheets/d/1tVm_u6v573V4NACrdebb_1OsBEAz60dS1m4pCTckgyA- 5 replies

Hello! I found them in Western Ukraine. Help, please, with identification. Are they Gastropoda moluscs? Which type of replacement it is? And from which period it could be (I found fossils in this place from Neogene and Cretaceus)? Thanks in advance!!!

Someone brought in this nice steinkern of a large gastropod found last week in the Middle Devonian Columbus Limestone near Columbus, Ohio. It is likely Pleuronotus decewi. Because I don't yet have this taxon (nor any palaeozoic gastropod taxa of that size), I took the opportunity to mold and cast it. Here is the fossil: Here is the fossil (lower) and two casts I made (above). These have a base-color that was added to the casting medium, but no color matching paint treatment has yet been applied (these are hot off the "press").

A gastropod from the Lower Campanian of southern Poland. Any ideas on what group may it belong to, based on the ornamentation?

UPDATE: This could be Murchisonia sp. which has been recorded from the underlying Dundee Limestone and deposited in the Ohio State University Museum of Biological Diversity. Hello, I found a rare conispiral gastropod steinkern in the middle Devonian (Givetian) Silica Shale of Paulding, Ohio, last week. It's the first strongly conispiral gastropod I've ever found in the Middle Devonian (let-alone the Silica Shale). I looked through the FUMMP online database as well as the "Strata and Megafossils of the Middle Devonian Silica Formation" published by FUMMP and couldn't find any taxa that looked like this. It has the general shape of Paleozygopleura known from the Hamilton Group of New York. Is anyone aware of a snail with this general morphology that has been reported from the Silica Shale? Scale in mm.

Straparollus (Euomphalus) is likely an early gastropod that is relatively abundant in certain Graham Formation (Pennsylvanian) exposures in the area around Jacksboro, Jack Co., Texas. Smaller specimens like those pictured are occasionally referred to as Schizostoma, which is currently considered a synonym. EDIT: Pennsylvanian is Subperiod, Late is Epoch.

I've googled and googled but can't find a definitive family tree for ammoniods/cephalopods &c. I'm looking for relationships between ammonites, nautiloids, belemnites, turrilites etc. Does that make sense? Thanks J
