New Members Samantha H Posted April 13 New Members Share Posted April 13 I live at the bottom of a hollow in Buffalo Valley, TN. It was obviously under water at some point as I have tons of rocks with shell fossils all up my hill. I find crinoids all the the time. This is the first that I've found that looks like this though. It's maybe the size of a quarter. Is it a vertebrae from something? 1 Link to comment Share on other sites More sharing options...
BobWill Posted April 13 Share Posted April 13 This is most likely a nautiloid. Since it is mostly encased in matrix it may be hard to further identify without any details showing. There is a small chance it could be one of the planispiral gastropods that coil in a single plane but my guess is nautiloid. 1 Link to comment Share on other sites More sharing options...
Fossildude19 Posted April 13 Share Posted April 13 Without removing more matrix from around the item, it is difficult to pin down an ID for this. Nautiloid is a good possibility, but I wouldn't rule out a Bellerophrontid gastropod. 2 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

TqB Posted April 13 Share Posted April 13 (edited) The flaring bottom whorl looks more bellerophontid than most nautiloids. And there's no sign of nautiloid chamber walls in the top whorl, unless it's still the living chamber at that point.
