Lone Hunter Posted March 9, 2021 Share Posted March 9, 2021 This was given to me many years ago by a Texas fossil hunter, of course I didn't write down what he said it was or where it came from and haven't seen anything that resembles it except my box turtle which it definitely is not. Hoping someone recognizes it and this time I will make note! Link to comment Share on other sites More sharing options...
Thomas.Dodson Posted March 9, 2021 Share Posted March 9, 2021 Could we get side images (the arrows)? In some images it looks like it could be a bellerophontid mold. Image 4 doesn't look like it though. Link to comment Share on other sites More sharing options...
Lone Hunter Posted March 9, 2021 Author Share Posted March 9, 2021 Hard to get a clear shot of all the angles, start with these. Link to comment Share on other sites More sharing options...
Thomas.Dodson Posted March 9, 2021 Share Posted March 9, 2021 Interesting... Doesn't look like a bellerophontid anymore. Hopefully someone else will know what it is. Link to comment Share on other sites More sharing options...
Lone Hunter Posted March 9, 2021 Author Share Posted March 9, 2021 Appreciate you taking a look, I know it's something, and it may be older than Cretaceous. Link to comment Share on other sites More sharing options...
Lone Hunter Posted March 9, 2021 Author Share Posted March 9, 2021 Don't know if this will help but was given this along with it. Want to say I was told it was Jurassic. Link to comment Share on other sites More sharing options...
Rockwood Posted March 9, 2021 Share Posted March 9, 2021 My sense is that it's a fragment of a larger shallow moving water sedimentation pattern that has dried and cracked. Link to comment Share on other sites More sharing options...
Lone Hunter Posted March 9, 2021 Author Share Posted March 9, 2021 I think I have one of those, the composition looks very different under magnifying glass though. Also don't think this person would have given me something not significant but since my memory fails me it very well could be just cracked mud. Thank you for all the feedback and knowledge you give.

Rockwood Posted March 9, 2021 Share Posted March 9, 2021 I think we are fully into the septarian concretion family now. 1 Link to comment Share on other sites More sharing options...
jpc Posted March 9, 2021 Share Posted March 9, 2021 This last one is definitely a septarian concretion. 1 Link to comment Share on other sites More sharing options...
Thomas.Dodson Posted March 9, 2021 Share Posted March 9, 2021 As others have said, the last one is definitely a septarian concretion. The second specimen is a gastropod. It reminds me of Trepospira but wouldn't fit with Jurassic and lots of snails are similar (it's only one picture anyway). This is why geographical location and age information is so important to identification. Link to comment Share on other sites More sharing options...
Lone Hunter Posted March 9, 2021 Author Share Posted March 9, 2021 Thanks to all for clearing that up, sort of, why wouldn't the first one be considered like a septarian nodule of sorts? Link to comment Share on other sites More sharing options...

Lone Hunter Posted March 10, 2021 Author Share Posted March 10, 2021 I would be interested in seeing another example of cracked sedimentation that isn't flat if anyone runs across one! Link to comment Share on other sites More sharing options...
ClearLake Posted March 10, 2021 Share Posted March 10, 2021 Your gastropod looks like a Pennsylvanian Trepospira discoidalis which are common in Texas (or at least in areas of Texas with Pennsylvanian rocks). The other piece has the coloration that I have seen in some Pennsylvanian concretions and such out of Texas. 1 Link to comment Share on other sites More sharing options...
Lone Hunter Posted March 10, 2021 Author Share Posted March 10, 2021 Yes you nailed it! Mystery solved and I'm writing it all down this time, thanks so much! Link to comment Share on other sites More sharing options...
