Roz Posted October 31, 2014 Share Posted October 31, 2014 I have done quite a few searches and read crustacean papers but I cannot reach a conclusion. It was suggested that it may be an arthropod, maybe crustacean. Does anyone think that this looks likely for arthropod? It was in a nodule. It is from the Pennsylvanian Period. Thanks for looking!

fossilized6s Posted October 31, 2014 Share Posted October 31, 2014 Here's a bit lighter pics. I can't make anything out.

Fossildude19 Posted October 31, 2014 Share Posted October 31, 2014 Hmm. Maybe a fish scale? Took the liberty of brightening up your pics, Roz!

fossisle Posted October 31, 2014 Share Posted October 31, 2014 Could be a nautiloid jaw? Cephalopods rule!! Link to comment Share on other sites More sharing options...

LanceH Posted October 31, 2014 Share Posted October 31, 2014 Roz's monitor needs to be gamma adjusted. I just see blackness. Link to comment Share on other sites More sharing options...

Missourian Posted October 31, 2014 Share Posted October 31, 2014 FWIW, the phosphatic unit that produces these concretions -- Lower Wolf Mountain Shale -- is apparently equivalent to the Muncie Creek Shale of the northern Midcontinent (Kansas, Missouri, etc.), which produces very similar PO4 concretions. This means the conditions that produced this type of preservation were spread out over a wide area. Context is critical. Link to comment Share on other sites More sharing options...
Roz Posted October 31, 2014 Author Share Posted October 31, 2014 Thanks for the lighter pics guys! I appreciate it. The odd thing is that they look fine on my computer so maybe it is the gamma. Mitch is right about the Wolf Mountain and Muncie Creek Shale info. Thank you for adding that. I have never seen a nautiloid jaw before so I went online and saw one. Unusual looking! Thanks for that suggestion, fossisle. I wish there were more examples out there for comparison. I only saw one fossilized. Tim, I have found quite a few fish scales but this one doesn't look right to me for a scale. I don't know what those raised ridge-like areas would be. Welcome to the forum!

Nandomas Posted November 1, 2014 Share Posted November 1, 2014 Just a wish rather than a try: could it be a partial, deflated shark eggcase ? Erosion... will be my epitaph! http://www.paleonature.org/ https://fossilnews.org/ Link to comment Share on other sites More sharing options...
Auspex Posted November 1, 2014 Share Posted November 1, 2014 Just a wish rather than a try: could it be a partial, deflated shark eggcase ? Good thought!

fossilized6s Posted November 1, 2014 Share Posted November 1, 2014 Just a wish rather than a try: could it be a partial, deflated shark eggcase ? That actually makes the most sense so far given the wrinkled texture. Roz, is this a freshwater, brackish or saltwater site? What do you normally find? I found my shark egg case in a brackish water site that yields quite a lot of terrestrial material (ferns, cyperites, lycopods, etc.). ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...
Roz Posted November 1, 2014 Author Share Posted November 1, 2014 The Canyon Group - Missourian Stage where I am hunting shows it as shallow sea. It is also has that area pictured as the Lobate Delta and the open shelf on a map I have. I haven't found much plant material at this site although I did find one seed and other plant material including fusian. The majority of finds are fish with quite a few nautiloids and some ammonoids coming in next. Some trilobite material also and shells. I forgot crinoid material. Welcome to the forum!

tmaier Posted November 1, 2014 Share Posted November 1, 2014 Thanks for the lighter pics guys! I appreciate it. The odd thing is that they look fine on my computer so maybe it is the gamma. I once did a bunch of color and brightness correction to about 30 images of my fossils, only to find out later that the red channel of my RGB had a loose connection, so I was viewing GB with no R. That made all the corrected images come out really weird. The other terrible thing was that I had made the corrections on the original image files instead of creating new files, so I had mangled all the originals. I've learned to look at the quality of known good images before tweeking anything, and to avoid modifying the original files (so you can always go back).

Roz Posted November 1, 2014 Author Share Posted November 1, 2014 Yes, I have some trepidation regarding making computer changes, as in the past I changed a few things before understanding the consequences. Thanks for the tip! Welcome to the forum! Link to comment Share on other sites More sharing options...

I've learned to look at the quality of known good images before tweeking anything, and to avoid modifying the original files (so you can always go back). For just this reason, I use a free program called Photoscape. It automatically creates a folder called originals, and puts a copy of the original image into that folder - I never have to worry about messing up a picture. Also, it is very intuitive, and easy to use.

Roz Posted November 2, 2014 Author Share Posted November 2, 2014 This map is from the book, "Pennsylvanian Fossils of North Texas". Mark gave me permission to use maps in it to explain myself. The black square is Bridgeport (the area I found this fossil) and the round circle is Jacksboro approx. I think this will give a better idea of what conditions it came from. Welcome to the forum!
