New Members Fossilcal Posted May 25 New Members Share Posted May 25 Hi there, I found this in Fannin county, Texas and it is fossilized but not quite sure what it is. It looks to me like the start of a pinecone. Any help with ID would be very helpful. Thank you Jim 1 Link to comment Share on other sites More sharing options...
DPS Ammonite Posted May 25 Share Posted May 25 Welcome to the Forum. Is it made of lignite or coal-like? In other words, is it hard and mineralized? My goal is to leave no stone or fossil unturned.

DPS Ammonite Posted May 25 Share Posted May 25 I see layers, but not individual bracts. Can you show an up close picture of some bracts? Maybe a phosphatic or iron rich concretion. What color is its streak? My goal is to leave no stone or fossil unturned. See my Arizona Paleontology Guide link The best single resource for Arizona paleontology anywhere.

New Members Fossilcal Posted May 25 Author New Members Share Posted May 25 (edited) Here’s a few closer up pictures. It’s lighter brown to dark brown. Edited May 25 by Fossilcal 1 Link to comment Share on other sites More sharing options...
Al Dente Posted May 25 Share Posted May 25 Looks like a spiral coprolite from a shark or fish. 4 Link to comment Share on other sites More sharing options...
Coco Posted May 25 Share Posted May 25 That’s what I thought too, we should check that it is indeed a spiral. If so, it would be a particularly well preserved coprolith. Ho much is it size ?

New Members Fossilcal Posted May 25 Author New Members Share Posted May 25 I thought it was well preserved also. I’m going to look at it today under a microscope. It’s only about 7/8” long and a 1/4” wide. Link to comment Share on other sites More sharing options...
Randyw Posted May 25 Share Posted May 25 (edited) In the middle picture of the second set of pictures. I'm pretty sure I can see a definite spiral... I'm in the coprolite camp myself.... Edited May 25 by Randyw Link to comment Share on other sites More sharing options...
New Members Fossilcal Posted May 25 Author New Members Share Posted May 25 (edited) Just took theses pictures under a microscope and it looks like a pinecone and some spots of amber also in the whorls. Edited May 25 by Fossilcal 2 Link to comment Share on other sites More sharing options...
ThePhysicist Posted May 26 Share Posted May 26 I agree with the others, shark coprolite. Remember in Fannin county you're in Late Cretaceous marine deposits (NSR or a branch of it I'm guessing), so shark feces should not be surprising. Nothing you've presented supports it being a pinecone. Conifer seed cones have well-separated "scales" that are in arranged in a number of geometric patterns, not a continuous spiral as seen here. Hope this helps!
