Littlebit Posted August 9, 2019 Share Posted August 9, 2019 Very much an amateur here. Recently some farmland in east Tulsa was scraped off for a new housing addition. I have found lots of crinoid stems and a few shells and trilobites. But I don’t know what this is that I found today. Can anyone help? Link to comment Share on other sites More sharing options...
JamieLynn Posted August 9, 2019 Share Posted August 9, 2019 not my area of expertise, but thinking perhaps an Orthocone cephalopod shell? www.fossil-quest.com Link to comment Share on other sites More sharing options...
connorp Posted August 9, 2019 Share Posted August 9, 2019 Possibly a nautiloid. Could we get more shots, including on the sides and directly of the cross section? Link to comment Share on other sites More sharing options...

Rockwood Posted August 9, 2019 Share Posted August 9, 2019 I think it looks more like a trace fossil. It's a little to chaotically structured for a body. Link to comment Share on other sites More sharing options...
Scylla Posted August 9, 2019 Share Posted August 9, 2019 Is this in a karst formation? If there is a lot of limestone in the area then this might be a dripstone formation, i.e. stalagmite or stalagmite. That would be consistent with the circular pattern on cross section.

There appears to be a small gastropod at about 4 o'clock on the "cut" surface, so unlikely to be stalactite. I thought cephalopod at first thinking the circular spot was a siphuncle. But the gastropod makes me lean towards @Rockwood's ID. The pictures asked for should help to ascertain an answer. Mike Link to comment Share on other sites More sharing options...

Mike I only have my cell phone, so I can't see a gastropod, although I have seen thousands of fossil gastropods in a dripstone cave in Ha Long Bay in Vietnam. It was inhabited by paleo humans who ate the (then) freshwater snails and now the whole area is ocean. Anyway I still agree that a gastropod fossil embedded in this rock makes dripstone very unlikely. Did you see the crinoid columnal in the chert?
