apple3.14 Posted July 28, 2021 Share Posted July 28, 2021 I found this and quite a few other things in a nodule layer of Pennsylvanian in Catoosa, OK. This is my first post here so I'll just try 1 for now. Thanks Link to comment Share on other sites More sharing options...
connorp Posted July 28, 2021 Share Posted July 28, 2021 Looks like a cross section through bone. Not sure if much else can be said with splitting the nodule further. Maybe a more astute member could hazard a guess if you post a larger and higher resolution photo of the cross section. Link to comment Share on other sites More sharing options...
apple3.14 Posted July 29, 2021 Author Share Posted July 29, 2021 thank you I'll try taking a few better closeups tomorrow Link to comment Share on other sites More sharing options...
Rockwood Posted July 29, 2021 Share Posted July 29, 2021 Hazard here. Looks like plant material to me. Tree fern would be my best guess. Link to comment Share on other sites More sharing options...
jdp Posted July 29, 2021 Share Posted July 29, 2021 (edited) I'm pretty confident this is a rostrum from the fossil swordfish mimic Protosphyraena. If so, this is Cretaceous rather than Pennsylvanian Edited July 29, 2021 by jdp 1 Link to comment Share on other sites More sharing options...
Rockwood Posted July 29, 2021 Share Posted July 29, 2021 Wow ! That'd be quite a schnoz. Guess it could be. Link to comment Share on other sites More sharing options...
Carl Posted July 29, 2021 Share Posted July 29, 2021 I'm also definitely seeing bone, Beyond that, I'm stumped. But if this truly is Pennsylvanian, it could be quite important. 1 Link to comment Share on other sites More sharing options...
Top Trilo Posted July 29, 2021 Share Posted July 29, 2021 Geologic map says the area around Catoosa is indeed Pennsylvanian, and I agree with the others, looks like bone. “If fossils are not "boggling" your mind then you are simply not doing it right” -Ken (digit) "No fossil is garbage, it´s just not completely preserved” -Franz (FranzBernhard) "With hammer in hand, the open horizon of time, and dear friends by my side, what can we not accomplish together?" -Kane (Kane) "We are in a way conquering time, reuniting members of a long lost family" -Quincy (Opabinia Blues) "I loved reading the trip reports, I loved the sharing, I loved the educational aspect, I loved the humor. It felt like home. It still does" -Mike (Pagurus) “The best deal I ever got was getting accepted as a member on The Fossil Forum. Not only got an invaluable pool of knowledge, but gained a loving family as well.” -Doren (caldigger) "it really is nice, to visit the oasis that is TFF" -Tim (fossildude19) "Life's Good! -Adam (Tidgy's Dad) Link to comment Share on other sites More sharing options...
jdp Posted July 29, 2021 Share Posted July 29, 2021 Yeah, and the other fossils from this site are all obviously Carboniferous. But I honestly have no clue what this is and I've only seen this anatomy in much later taxa. Maybe really weird preservation of a ctenacanthid fin spine?

If so, this is Cretaceous rather than Pennsylvanian I did see a picture of a rostrum while trying to identify it and it looked pretty close but bigger I think. I have tried to find a better way to find the era but everything I found showed the whole area being in the Pennsylvanian. I also posted a few things last night that were all from nodules that came from the same 8 inch layer that this piece was found. Link to comment Share on other sites More sharing options...

Here are a couple more cross sections and another piece I found but haven't posted yet. Link to comment Share on other sites More sharing options...
westcoast Posted July 30, 2021 Share Posted July 30, 2021 Very curious! Can you confirm if the bone-like v-shaped structure seen in cross-section is surrounded by nodule minerals (siderite?) or if there is boney texture throughout the entire piece?

I think its nodule material outside the V structure but I can't see a distinct outer bone layer on either one so I'm not 100 percent sure. 1 Link to comment Share on other sites More sharing options...
