I’m struggling to identify this. The closest I’ve found is possibly a fossilized crayfish gastrolith. But I could be way off. I’m very new to fossil ID. I do find a lot of marine life fossils in my area. I had thought perhaps brachiopod, but it looks nothing like my other one. I’ve included a photo of the unidentified piece along side my brachiopod so if I have misidentified it please correct me. Thanks in advance. Details: Northeast Arkansas Mississippi Alluvial plain Along the Eastern edge of Crowley’s Ridge I’m 93% certain the material is quartz (chert)

My only true "questionable" find whether it is something or not. I love learning about geology, that said after we purchased 3 acres on land which was under glacial units (Puget lobe in WA state, possibly Pleistocene) I dug a hole near what would have been a bank however many thousands of years ago (16,500 years ago would have been glacial outwash). I crack rocks open to see mineral composition. This was found slightly above (maybe 1'-2'), what I would label the alluvial line, but I am very much an amateur when it comes to defining specifics. Google fish fossils and there is nothing like it, I personally see clear and distinct fin outlines. BUT that is why I would LOVE to hear your feedback and any thoughts! This "fish outline" is small, 3.5" x 1". But if a fish i would think pretty rare find based on our locations climate/environment. Thank you for your time!

Ok, still new at this fossil hunting thing. Went poking around today in an Alluvial Creek bed in the Goliad formation of Duval County, Texas. We found an ammonite here a few weeks ago and were searching for more when my daughter found a bone in the side of a bluff, about 6’ to 8’ above the creek bottom which is always dry here. It seems slightly petrified but not hard as a rock. It is very brittle. Not sure if this is a cow from 50 years ago (or 10 years ago) or something more exciting. It was buried under a lot of pebbles and sand on the side of the Bluff. We’re still out here searching other areas but I can post better picks later tonight. Thanks!
