I’m not sure what this is. This little croissant shaped guy struck me as interesting as I was hunting through a pile of limestone in our new construction neighborhood in northern Bexar County, Texas. It’s in northern San Antonio. I thought it might be a shell of some sort. It’s about 4.5 to 5 inches wide and about 1.5 inches in depth. It has striations here and there and a shape that looks like a nautilus, but may just be an interesting concrete on or piece of limestone. Anyone got any ideas or answers? The ‘center’ of the ‘croissant’ has a grayish area that’s really different from the rest of it. Thanks for any ideas!!!

Good evening everyone! Hope everyone is safe and healthy! Found this little (15mm) "ammonoid", that, to the best I can find is an example of a ridged ammonite Neoglyphioceras sp? (Unklesbay Common fossils of Missouri 1973). It was found in Pennsylvanian Winterset limestone in Kansas City. Is this a fair observation/guess? Thanks for any input! Bone

Finally getting around to posting a pic of a piece I found at last weekends "Dig with the Experts" (I was there Saturday wearing my FF shirt). Along with several enrolled Eldredgeops, a nice prone one, a few brachs and snails, I brought this piece home as well. It isn't the easiest to get a good pic of, but I showed it to several people there including other FF members and the PD staff and nobody had seen anything quite like it. The consensus is that it's a trace but the ridge running along the middle is what's causing people to scratch their heads. Has anyone ever seen a similar example? Thanks in advance
