PetrolPete Posted January 20, 2013 Share Posted January 20, 2013 These concretions are Pennsylvanian in age and were found in the somewhere in the Senora formation- oswego- fort scott boundary in north eastern oklahoma. A picture for scale: Possibly a jaw of some kind, but no idea of what: Some kind of bone, also no idea as to what it's from: And no idea at all on this one: Any and all help in IDing what these fossils came from/are, is greatly appreciated. Thank in advance. Link to comment Share on other sites More sharing options...
Missourian Posted January 20, 2013 Share Posted January 20, 2013 I can't help with id's, but those are some nice pieces. The first close-up specimen has some intriguing details. Could you get closer in on it? In Kansas City, we find similar nodules from the Muncie Creek Shale. Like with your deposit, we come across many different types of bones. We gleefully collect them, but with a few exceptions, we have no idea of the owners. Context is critical. Link to comment Share on other sites More sharing options...
Auspex Posted January 20, 2013 Share Posted January 20, 2013 Not the run-of-the-mill nodules! Is there a faunal list for the formation?

Roz Posted January 20, 2013 Share Posted January 20, 2013 Yes, could you get closer up for the other pics as well? Maybe take the pics outside for better lighting. I would love to see them closer... Welcome to the forum! Link to comment Share on other sites More sharing options...
AgrilusHunter Posted January 20, 2013 Share Posted January 20, 2013 Hi Pete, Those are some great finds! I'll be interested to hear what comes of the indentifications. That first one does have some interesting serrations that look like teeth! Very cool.

PetrolPete Posted January 20, 2013 Author Share Posted January 20, 2013 I'll work on trying to get better pictures and I'll throw in a couple other interesting concretions as well. As for the faunal list, there might be one somewhere, but I haven't found it yet. Unfortunately, the OKGS bulletins don't have searchable text so it takes a while to look through them all.

PetrolPete Posted January 21, 2013 Author Share Posted January 21, 2013 Here are two of the three concretions from earlier (I'm still working on the jaw, due to its shape it's hard to get it in the right light) Here is a bone I found at the same location, it had already weathered out of its concretion when I found it: And here is what a professor of mine I believe ID'd as a pelecypod: Link to comment Share on other sites More sharing options...
PetrolPete Posted January 21, 2013 Author Share Posted January 21, 2013 here is another concretion fossil, no idea on this one: For the possible formations I listed and for a moderately nearby location, the only faunal list I've been able to find was for the senora formation and can be found here:http://www.ogs.ou.edu/pubsscanned/BULLETINS/Bulletin70mm.pdf Link to comment Share on other sites More sharing options...
PetrolPete Posted January 22, 2013 Author Share Posted January 22, 2013 Ok, I got a better picture of the jaw: let me know if a better/different picture of anything might help with a possible ID. Thanks again Link to comment Share on other sites More sharing options...
PetrolPete Posted January 23, 2013 Author Share Posted January 23, 2013 After doing a lot of research, I've still been unable to find a complete faunal list with vertebrates (usually they stop at invertabrates) of any of the pennsylvanian formations around here, but I do know from a professor that there has been some evidence of fish, reptiles, amphibians and conodonts around oklahoma during that time. So I was wondering if anyone would be able to confirm or reject the possibility of the jaw being from any of these? Link to comment Share on other sites More sharing options...
CH4ShotCaller Posted January 23, 2013 Share Posted January 23, 2013 Very nice! The concretions from your locale are varied; each having something different. I'll certainly be watching future posts of your pics and finds!!

Roz Posted January 24, 2013 Share Posted January 24, 2013 I am sorry, Pete, I can't tell.. Do you have a loupe? If so on the possible jaw, you could place the loupe flush with your camera and get a really close up pic... Welcome to the forum! Link to comment Share on other sites More sharing options...

PetrolPete Posted January 24, 2013 Author Share Posted January 24, 2013 I don't know how well these turned out, It was a little difficult to work with the shape of the concretion so I think one side is a little distorted Positive side: Negative Side: Link to comment Share on other sites More sharing options...
Missourian Posted January 24, 2013 Share Posted January 24, 2013 It looks like your cam-loupe combo is working fairly well. When I'm doing it with my microscope, I'll take several photo (10 to 20), so at least one or two will likely be perfectly focused. Context is critical.

AgrilusHunter Posted January 24, 2013 Share Posted January 24, 2013 Hi Pete, Your new images are very good. Much clearer. I'm not sure on your specimen though, that is very different stuff that what I find in nodules in Indiana. I'll be interested to see what others think.

AgrilusHunter Posted January 24, 2013 Share Posted January 24, 2013 (edited) Hmmm ... I wonder if what you have is a portion of the carapace from a Xiphosurid. It looks different from the Euproops I've seen around here or from Mazon, but from where you are collecting who knows. The reason I say this is I don't see a lot of differentiation between the teeth/spines and the rest of the fossil. Just a thought any way.

fossiladdict Posted January 25, 2013 Share Posted January 25, 2013 (edited) Is the yellow area around the teeth actually enamel?

PetrolPete Posted January 25, 2013 Author Share Posted January 25, 2013 Is the yellow area around the teeth actually enamel? It's possible, I'll try and clean up the other teeth and see if anything shows up Hmmm ... I wonder if what you have is a portion of the carapace from a Xiphosurid. If looks different from the Euproops I've seen around here or from Mazon, but from where you are collecting who knows. The reason I say this is I don't see a lot of differentiation between the teeth/spines and the rest of the fossil. Just a thought any way. I had been toying with the idea of it being other things like a spine (not as in backbone) of some organism, but I hadn't thought of a Xiphosurid before. I know they existed during the same time period, but I have not come across any mention of them in any literature I've looked at for this region, but it is an idea I'll try to explore Link to comment Share on other sites More sharing options...
Missourian Posted January 25, 2013 Share Posted January 25, 2013 What other identifiable fossils have turned up in the nodules? Context is critical. Link to comment Share on other sites More sharing options...
PetrolPete Posted January 25, 2013 Author Share Posted January 25, 2013 (edited) What other identifiable fossils have turned up in the nodules? From this area the only things I've been able to identify from the concretions clearly are some orbi's (one was articulate), goniatites, possibly some ammonids, some pelecypods , and what look like some other types of shells. Everything else is just some type of bone, possibly a scale/plate or just unknown. Most of the nodules didn't even have anything in them, they just fall apart once they open and others have a weird, small, spongy center. There is a good chance that some might come from different formations though, the location is lake side and has eroded in a way that there is a beach covered in the concretions Edited January 26, 2013 by PetrolPete Link to comment Share on other sites More sharing options...
AgrilusHunter Posted January 25, 2013 Share Posted January 25, 2013 (edited) ... the location is lake side and has eroded in a way that there is a beach covered in the concretions ... Beaches and pennsylvanian nodules you say. Hang on, I'll be there shortly ... Seriously though, I think fossiladdicts question is the right one. If that yellow stuff is enamel then you know for sure it's a jaw. If not it could be something else. I was thinking more of the edge of the carapace not the spine.
