    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…
