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").

Dear The Fossil Forum members, I have those Cnidaria (and a few other unidentified Cnidaria genera) from Camadas de Alcobaça Formation, Kimmeridgian, Portugal. I would be interested in Neogene Bivalvia or Gastropoda. If interested drop me a line please. Kind regards, Ricardo

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.

First trip of the year today to the "Fossil Gardens" at Paulding, Ohio. This is quarry spoil of mid-Devonian age, Silica Formation. There was not a cloud in the sky, and temps were relatively warm at 43 deg. F. I was the only one there for most of the day, and it was extremely peaceful. What a great day. Here are pics of some of the finds. These are "farm fresh" and haven't even been washed yet, but I did take time to polish some horn corals and get some acetate peels (couldn't wait). A large Cystiphylloides rugose coral.

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.

Hello, I found this Gastropod while hammering a chunk of Lower Miocene Limestone at a beach in Northern Puerto Rico. In my opinion it's a nice fossil with some crystallization. The Description from the USGS on the limestone formation is: Hard granular calcarenite overlain by alternating beds of chalky marl and rubbly limestone Just wondering if any one could help me ID it. Thank you!
