I spent a VERY fruitful day at Ramanessin, but this one object has me both stumped and intrigued. Sorry for the terrible hotel room photos, and the pen for scale. Also have an altoids box for scale (heh). this object appears to be an internal mold of some kind, it is entirely fine mudstone with some fine gravel. The back (non-pictured) side is broken and shows the mudstone texture well. There is a distinct “cutting edge” to use tooth terminology on the intact side of the item. It has very distinct striations, and frankly it looks like a large.. internal mold of a tooth? I have no idea what

Hello dear fellow forum members, this is a fossil that I got as a gift when I was eight years old, as a fossil sponge. In the years after, I began to doubt if sponges fossilize and called it a coral, but maybe it really is a sponge after all? I think it is from the region around Porto Christo on the east coast, but cannot be sure about that. The east coast is mainly Miocene on the surface as far as maps tell me. There are jurassic and cretaceous fossils on the island also. Any ideas? Thanks, J

Found almost fully submerged in the wet sand beneath the waves of Holden Beach. It was found within newly replenished sand from dredging that’s occurring currently a couple miles off the coast. Very heavy and dense(1.257kg), porous of course and it’s not perfectly symmetrical at any angle I view it from. I’d guess some whale bone but I know very little about fossils. There’s also tens of thousands of Hardouinia Mortonis (PeeDee Cretaceous) coming up through the dredge pipes if that helps in any way. Longest length ≈ 15cm Longest width ≈ 10cm Longest depth/height ≈ 8cm Narrowe

Most of what I find in southeast Texas is mio-pleistocene, and fresh water based. But at times older cretaceous stuff washes down. Since it's rare here, I'm completely clueless as to differences between oysters, corals, rudists and things but would like to learn more. I found this a while back and it seems to have very distinct patterns on the outside and inside. From searches, I thought maybe a broken piece of rudist, but I wouldn't know one if it bit me. It just doesn't look like normal rock to me. Any guidance would be appreciated. @JohnJ

Hello, Any idea what this might be, where from? Possibly a madagascar fish nodule? The seller just says "probably cretaceous", doesn't seem to know much else. 13cm length. Also while I'm at it, can I ask if any part seems restored or enhanced? Thanks.

Hi everyone! I acquired this in an estate wholesale with a bunch of other ammonites (mostly Moroccan and Madagascan). This one caught my eye immediately as I don't know how to id it or even where it came from (I think it's Russian just by comparing it to pictures of other pyritized ammonites but I'm not 100% sure). The interior has been completely pyritized and some of the aragonite shell remains which is pretty unique. Any help on where this could have come from, age, and genus would be greatly appreciated.

I found this rock a couple months ago in a small community in Denton County, Texas. I think it could be a fossil rib bone or some other kind of fossil bone. I was originally thinking it was a manatee rib bone, but after more research I started to doubt the possibility of it being a manatee...and I'm pretty sure you can't find fossil manatee bones in Texas. Anyone know what this is?Is it just a rock or an actual fossil?

I would greatly appreciate any help in identifying this "fossil". This "fossil" was found on the ground in an area where limestone was being dump on the ground for a pad or road. Central Texas; probably Frio county. Thank you.

Found this fossil in central Texas (Glen Rose formation), but it was found in rock that was hauled in around my sister's house. So I don't know if it's Cretaceous or not (sure looks like central Tx limestone, tho).

A dinosaur bone from Beckham's Barn. Is it from a sauropod? Any ideas?

While I was going through a bunch of my 'collection' boxes with all my fossil crustaceans to put into my new display cabinet, I ran into this little plastic bag. This box is at least 12 or 13 years old and some of the fossils were things ive prepped about 20 years ado. I have no idea as to where I acquired this tooth? I use to be a very prolific trader back in the day and I cant remember everything anymore. No idea as to the local of this specimen. Im also not a tooth guy. Im hoping that someone here has an idea to what it tooth is. Oh, it measures about 3 inches. RB
