icycatelf Posted January 3, 2016 Share Posted January 3, 2016 (edited) I was rummaging through rocks that the county had filled in a hole on our property with and found these. The first I'm very confident is a horn coral, though there are some other things in the matrix that I'm not sure about. I've pointed out a few things specifically, but let me know if you spot any others! At the right end of the coral is a broken washer shape (less than half a centimeter wide). Partial crinoid column? Someone told me that the specimen to the left may be Favosites coral (1cm visible) and the layered pieces to the top right (I see two, though the furthest right is blurry in the photo) may be crinoid stems (less than half a centimeter wide, about the same size as the "washer" on the front). A lump at the top (1cm wide). It seems more spherical than the "washers," but also appears to have a hole in it. Texture and sheen isn't consistent with orb-like parts of crinoids. Someone mentioned that it may be a brachiopod of some kind. Someone mentioned that this "stick" may also be part of a crinoid stem (as well as the other washer-like shape to the upper right of it, which is shiny like crystal). (Same width as other possible crinoid stem pieces.) This was my other find. Possible brachiopod mold (1cm wide)? Closeup: Edited January 5, 2016 by icycatelf Casual surface-collector and Pokémon fan.

Pumpkinhead Posted January 3, 2016 Share Posted January 3, 2016 That first one looks like a horn coral to me. I'm getting a Devonian vibe off of these rocks Link to comment Share on other sites More sharing options...
icycatelf Posted January 5, 2016 Author Share Posted January 5, 2016 (edited) I emailed a paleontologist about these and added his opinions to the first post. More thoughts, anyone?

Pumpkinhead Posted January 7, 2016 Share Posted January 7, 2016 1) Definitely a horn coral. The "washer" thing you noticed does seem to be part of a crinoid stalk. 2) This does seem to be a tabulate coral, a view of the top of the coral on the top left of the specimen would tell me whether or not it is favosites. It probably is. 3) Could be a view of the top of a brachiopod shell, but there is nothing particularly obvious about that fossil. I have no strong conclusions. 4) Again, nothing seems very defining. It could be a worn crinoid column section or a coral. 5) This looks more like a conulariid imprint, although occasionally I see what I believe are imprints of rugose corals that look similar. I don't think its a brachiopod Link to comment Share on other sites More sharing options...
icycatelf Posted January 7, 2016 Author Share Posted January 7, 2016 Thanks for the feedback. If I can think about it, I'll try taking some better-quality pictures on the next clear day. Casual surface-collector and Pokémon fan. Link to comment Share on other sites More sharing options...
