3 years, 11 months ago3 years, 11 months ago@dawn-vitale@samantha-ocon So Sturgeon and Miller published on some Pennsylvanian cephalopods from Ohio but in their paper they also talk about them being in PA too. Looks like there is some shared geology. Maybe it’s in one of their two publications. Here is the link for one: https://www.jstor.org/stable/1299256?seq=1#metadata_info_tab_contents.…[Read more]

3 years, 11 months ago3 years, 11 months ago@dawn-vitale@samantha-ocon@jbauer I think it might be a cephalopod? Sort of looks like chambers and sutures with outside ornamentation. Where was it found?

3 years, 11 months ago3 years, 11 months agoHi, @Dawn-Vitale. Would you be interested in improving the data associated with this specimen so we can keep it in the eMuseum? I can walk you through the process if you’re interested.

3 years, 11 months ago3 years, 11 months ago@jbauer Neat! I’ve seen rocks like this before, and I often can’t quite determine if they’re wood either.
@dawn-vitale Hi, Dawn! What do the edges look like? I wonder if there’s some indication of rings or a bark layer or something.

3 years, 11 months ago3 years, 11 months agoAwesome find @dawn-vitale !!! @matthew-gramling is right the brachiopod class is Rhynchonellata. Do you have a smart phone? I would download the RockD app- you can use it to record localities you visit (and it shares other folks spots) and get the geologic age – which helps a lot with fossil ID!

3 years, 12 months ago3 years, 12 months agoHi, @dawn-vitale – this looks like it could be a fossil coral but it could also be an oddly weathered rock.

3 years, 12 months ago3 years, 12 months ago@dawn-vitale@jbauer I can’t say if it’s wood or not. From the picture it looks like the texture could be caused by turbidity in the water at the time it was formed. Again, hard to say one way or another.

3 years, 12 months ago3 years, 12 months agoHi, @dawn-vitale – really interesting specimen, how were you able to identify it as wood? There is certainly abundant wood in that area but I’ve never collected there and am interested in your process. @mackenzie-smith is our resident fossil plant expert.

3 years, 12 months ago3 years, 12 months agoHi, @dawn-vitale – interesting specimen, are there fossil remains in there? It looks like maybe there could be some impressions but it mostly looks like a strangely weathered rock!

3 years, 12 months ago3 years, 12 months agoHi, @dawn-vitale – I’m not sure I see any specific fossils. Do you see anything you could direct my eye to?
Thanks, Jen -

4 years ago4 years agoHey @dawn-vitale! The Carboniferous was the second to last time period of the Paleozoic Era, meaning that’s it a couple hundred million years older than the time of the dinosaurs (Mesozoic Era). The Carboniferous is divided into two smaller periods of time known as the Mississippian and then the Pennsylvanian. Pennsylvania is actually known for…[Read more]

4 years ago4 years agoHey @dawn-vitale ! I don’t believe this a fossil. If it is, it’s been heavily crystallized.

4 years ago4 years agoHey @dawn-vitale ! I believe this is just a mineralized rock. If you could take a few photos from different angles, that could help determine what it is.

4 years ago4 years agoHi @Dawn-Vitale, would you be interested in updating the classification to reflect that this is part of a crinoid? That would be Kingdom -> Animalia, Phylum -> Echinodermata, Class -> Crinoidea

4 years ago4 years agoSorry, @Dawn-Vitale! I accidentally deleted your comment!! I was going to tell you that https://macrostrat.org/map/#/z=1.5/x=16/y=23/bedrock/lines/ can be very useful for figuring out the age of the rocks where you found this.
