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!

I've been going through some unknowns from various past hunts and here is one mystery. This piece looks like it should be familiar and I feel like I've seen it somewhere. This object is about 5.5 cm on longest dimension. It is hard/mineral--not modern bone. It was found in stream gravels at a site that is nearly pure marine Oligocene. Some Pleistocene material is theoretically possible, but I've never found it here. The site is richly fossiliferous with a variety of vertebrate/invertebrate material. Common vertebrates include: sharks/rays/sawfish, bony fish, turtles, crocodilians, toothed/baleen whales, manatee/dugong. My best guess is that it is a ceremonial helmet, once worn by ancient tiny gnomes during demonic rituals. On the off chance I'm wrong about this, who has another idea? It could be a modern human artifact for all I know, but it looks bony and has a foramen-looking hole that brings to mind words like "neural", "vertebral", or "cranial". Thanks for looking. G

hey guys, I'm back and probably don't have a fossil again haha but one of these days I will! I was wondering if anyone could help me ID this. I have found many rocks that are a similar shape to this. it tends to be difficult for me to tell from online pictures/descriptions, mostly because I’ll see shale and be certain its shale, but then I’ll see a picture of basalt, a random dark colored limestone rock, piece of chert, or even a fossil sloth claw or fossil tooth and then just have no idea because it could be any of the five depending on what photo I’m looking at haha. This is actually a very common problem I am having when trying to identify many different rocks (or possibly fossils) as my interest in fossils, rocks, minerals, and geology has recently grown. Also if anyone has any recommendations for a good intro book on fossils or rocks/minerals I’d love to hear them!! Maybe something more informative/technical than average kids book but not too academic/jargon-heavy/scientific/dry like a research paper would be awesome! Sorry about the link, imgur doesn't limit my upload size and my new iPhones pictures are massive so I have to resize to less than 50% in order to attach here. hope that's ok. there are 3 different rocks in the album, they are labeled. Menlo Park, CA according to the USGS survey of the bay area, I live in the Holocene alluvial section, bordering the Pleistocene alluvial section if that helps at all? found doing yard/landscaping work. its about 5 inches long but that's not exact, I can measure if needed. thanks in advance for any help and input!! https://imgur.com/a/IplRv

Quaternary Alluvial deposits, what to expect ?
Rocky Stoner posted a topic in General Fossil Discussion
Hi folks, My area in eastern WV is primarily devonian but the map shows some areas along the river as quaternary. The next time I go there, I plan to investigate some of the high banks, small cliffs and generally keep an eye peeled for anything out of the ordinary. What, if anything could I expect to find in this area ? Just wondering what features to focus on and what might be there ....... if anything. Thanks for any guidance.- 5 replies
