    Real cute Ambonychia slab from out back of the Walmart in Elizabethtown KY. Real productive and convenient location, anyone been there recently? #fossil #collectionsite

    Jennifer Bauer has contributed a new specimen to myFOSSIL!

    • This one is a trace fossil called Diplocraterion. Probably from the Kope

    • @jkallmeyer – I think I collected it in Peebles or that’s what the side of the rock says. The caption didn’t translate from the app to the web – hopefully we can get that fixed soon!

    • Agree with Jack that the trace highlighted by the black arrow is Diplocraterion. There might be other trace activity captured in that specimen as well?? Hard to tell from just one view but always interesting when you have both vertical and horizontal traces in proximity to each other. Infers different ‘critters’ and/or behavior and possibly changing depositional energy conditions.

    • @jkallmeyer & @todd-stephenson here is what my comment in the app said: “Diplocraterion trace fossils from Peebles, OH. These are really cool structures that appear as two openings on the surface, sort of like dumbbells. This is a U-shaped burrow that is interpreted as a dwelling chamber.” Hopefully we can get this issue solved so that the web-users can get all the information from the app!

      • The Ordovician strata near Peebles are Richmondian. If this is from the large-ish roadcut on Ohio Route 32 ~6 miles west of Peebles (east of Burnt Cabin Road), the one that goes all the way up to the Brassfield, that’s probably Liberty or Whitewater equivalent, maaaaybe Waynesville down at the bottom. But I’d assume this came from the upper part, which gets rather silty and tragically unfossiliferous, with trace fossils and thin bryozoans being the only signs of life in most beds. That’s mapped by the Ohio survey as the Preachersville Member of the Drakes Formation, which is probably at least in part Whitewater Formation equivalent, though that unit is a bit ambiguous and may be time transgressive (the type Preachersville down in Kentucky probably includes Liberty, Whitewater, and perhaps Elkhorn equivalents). More detailed strat work needed…

        • On my rock I had written down Whitewater but it sounds like Preachersville Member may be the proper identification, I’ll have to look into it a bit more. I wasn’t able to edit the specimen through the app once I uploaded it and haven’t had the chance to get back to it yet…

    Good sized cephalopod from the Cincinnati region. C5 sequence from Peebles, Ohio. Any identification suggestions from my friends in the Cincinnati Arch region? #fossil

    • Well, the C5 sequence has an abundant number of Treptoceras duseri. This is an orthocone nautiloid that fits your description and photo. Identification from internal molds like this is not foolproof. Using a photo is even harder. Try having a browse of publication USGS 1066-P and compare photos to your specimen. Here’s a link to the downloadable PDF. https://pubs.er.usgs.gov/publication/pp1066P

    • @bheimbrock – thanks for chiming in. That’s what I identified several others as from this region but I wasn’t sure about this one. It was much larger than the rest. Thank you for the link!

    Jen,Here’s a 3D preserved Kope graptolite free of matrix.  It’s probably the same species as yours which used to be known as Climacograptus typicalis.  That has changed to some other genus but I don’t recall what the new name is.   Scale bar is 5 mm Jack

    Jen, Regarding the old Cincinnati Fossils plates you mention below, those are from the original 1939 version published by UC and used as classroom guides. This UC set also had a few Silurian plates at the end.  The newer versions (1955 and after) ditched most of the bryozoan thin sections.  You need to come to our April auction this year because we have the entire 1939 book available. I’d call this a rarity and sought after by us old book nuts (place the emphasis any way you’d like regarding “old book nuts”).  The Silurian plates did not make it into the published book.  The 1945 version appears to me to be the rarest one as I only know of a few copies.  It is the only one to have a non-Ordovician critter on the cover – a sea horse!

    Alas, the Museum is adamant about never reprinting this old standby in any form.  It is out of print and Internet prices are ridiculous.  This $7.00 book is being sold on Amazon from third party sellers for $55 to $118!!  They intend to do a new book all updated but in different form.  I doubt we’ll see this for another year.

    Small bit of sediment with nice sized graptolites in it! I think this was collected from the Kope Formation. Can anyone confirm? Found the specimen in a backpack of mine with no associated information… must have been a last minute find! #fossil

    • What is a graptolite?? It’s a new creature for me!

    • Great question! These are microorganisms that live in colonies (the black saw-toothed object) and float around in the ocean feeding on particles in the water. They have a notochord like structure – notochords are one of the defining characters of vertebrates but these guys lack a vertebral column and other vert characteristics.
