I found this completely mineralized bone the other day on a river gravel bank. It's solid. It is pretty worn... but I figured there might be enough to get an ID. The size is 5 inches or 127 mm in length. I thought it might be a calcanea, but I also thought it might be the proximal end of a humerus. Thanks for your thoughts. In the 1st picture... I don't know if the side was highly worn prior to mineralization OR it had a deformity cause it looks like a mess. It looks too big for deer also. Don't think cow bone mineralizes as this is.

I found this the other day on a gravel bank. It could be a rock. The colors look alot like the enamel I've found before but this is a larger piece. It has an unusual shape. On an edge it has some lines that run parallel. I just haven't seen enamel like this other than the color.

I found this yesterday... and I was wondering what it is. I know skulls have sutures... and this looks like a suture to me. I have no clue, but are there other bones that have sutures... say like rib or leg bones? I don't think it's a break and there's not any ends to make an ID on what mammal it belongs to. It's completely mineralized. It really does looks more like a suture line than a break. It's not a great bone and probably a scrap... but I was just curious as to what other bones I could expect to see this on as I hadn't seen it yet. Found on a gravel bank.

I found this puzzle yesterday. There's not much to go on for an ID. It's definitely a small bone... it's mineralized. But this thing is shattered. Broken. Fragmented and in pieces like a puzzle. And it's been filled in throughout all of the fractures by matrix or sediment. I started to clean it up but I found the matrix is what's holding it together so I wanted to just leave it that way. It's pretty neat. But my questions is this @GPayton cause you've probably seen it down here. I found another piece that I think is wood but how does this happen? Is it crushed before and quickly filled in and mineralized and if so how does it even maintain its shape? Or does matrix fill in after mineralization through a break then expand and shatter the rest?? And I think it is bone. Could be wrong but it looks like it.

Found this big chunk of bone this morning and it's crazy heavy and is full of foramen, canals, chambers you name it. The bone is thick and for the life of me I can't recognize anything on it other than maybe the top of the skull divided where a suture might have been. Maybe. Even then the rest of it puzzles me. Can't find an eye socket or where a nose would be or anything else. Anyone recognize anything?? It's about 10 inches long. Sorry yall I use my phone I know on a desktop or laptop computer this is a lot of images... I tried to get as many angles and hopefully one of those will be what someone needs to recognize it. River gravel bank find.

I found this about an hour ago on a river gravel bank. It's a phalanx (toe bone) I think. But to what? It's 4.25" It seems to have a slight curve to it. Any thoughts? It has wear but is solid.

I found this small bone yesterday. It's solid and is 1.75 inches long. It's scrap and I know an ID to mammal is not gonna happen. Out of curiosity, and cause I like to inquire about everything, I was searching for something similar online and I was wondering if this might be part of a toe bone? I was trying to figure out why that indention was so large for such a small bone. I don't think it's a very small distal end to a humerus... so a phalanx seemed closer but even then I'm not sure. Maybe even the worn broken end to a deer leg bone? Would be nice to have the other side and middle... and the rest but I'm just curious and trying to solve this puzzle. If not, it'll go to the pile.

I found this today, Friday, on a gravel bank. At first I thought it might be a femur head which I found one of those today too... then I thought it could be a large occipital condyle. The last one I found was to an Eremotherium... could this belong to something else large like mammoth? It is pretty beat up and worn... but I think there might be just enough to at least ID the specimen instead of the mammal. It's 4 inches across.

I found this small chunk the other day. It has large foramen throughout... so I'm thinking it might be part of a mammal skull? Would it be from a larger mammal or do smaller mammals have openings that large as well? I couldn't orient it in any way to help and I know there's no way for an ID with it being just a chunk of an interior something. So, is a skull chunk the only possibility? Found on a gravel bar. Didn't measure as there's not much to go on. Oh and a river bug did come out for photos in a couple of them if you see him.

I believe this is an Equus tooth fragment like the other post based on what's left of the chewing surface. Again this is loaded with dentin or cementum. It seems like whatever it is... wraps around the outside of the tooth to the inside which is weird. It seems like something that would happen after its been broken. Maybe I'm wrong, sit just seems like it's the same on all sides even the broken side. And the dentin/cementum is solid on the tooth... it appears like it's about to flake off... not at all. It's on there pretty good.

I found this small tooth fragment Tuesday on a river gravel bank. I think it's a horse tooth based on the chewing surface area... also I think it's missing quite a bit and is pretty beat up. I thought it was pretty neat seeing the different lines and "veins" in and around it. My question is this: Is that dentin OR cementum that is on what would be the interior of the tooth and I think on the side of it is a small exterior part of the tooth that also has it? My next tooth post is also a fragment that's loaded with this stuff. This tooth here is 1" in length and .75" wide. Thanks.

I don't know anything about claws... and I have learned that a river can wear down a bone to all sorts of shapes. I found this little bone today... seems like a bone. It is hollow within. One side (the inside i'll call it) is flat... well it kinda curves in a little. The outside has a roundness and a curve that seems to lead to a point that's not there anymore. I thought of a deer antler but at the end where the openings are...it has that curved center where it looks like a place to pivot? Again... it could all just be a bone that has been water worn to expose the interior which I don't recognize. Also...I don't know if those are bite mark intentions all over it. It's 1.8" in length. Maybe a hoof core??? Seems pretty small for deer but perhaps? I don't think they are hollow tho. Maybe they are.

Yesterday I went out hunting and found some neat fossils while searching a couple of gravel banks that I'm now posting to see if the ID is correct and to ask a few questions about it. The first is a horse tooth I believe might be a cheek tooth but I don't know the specifics... if it's upper or lower. Sorry it's in my hand... that was to get it closer to the light for clear images. But why does it look like you can see right thru the enamel?!?! Of all the things I've ever found... this is the most unusual thing I've ever seen. How could that happen?? The tooth is see thru. It also has an unusual bend or warp to it.

Went out for a couple of hours today and came back with some good stuff and lots of questions about different things I found. I haven't had a chance to clean the specimens up and will this evening... but I'll start with this one. Pretty sure this is a piece of tusk. I can see the cross bands in some of the images. Is the entire thing enamel? Don't know anything about enamel. I see what looks like 2 layers... are both completely enamel? Also... how would you know whether it came from a mammoth or a Mastodon? Found in SE Texas on a gravel bank.

Found this yesterday amongst other unusual items on a gravel bank near the transparent tooth I recently posted. Based on the chewing surface... is this an Equus? I think it is missing the part where a protocone would be. It has beautiful colors. Lately I've been finding some unusual colored specimens. There's gotta be something in the water here.

I found this tooth today. It has a stylid which leads me to BOS or Bison. From what I read....Camels didn't have stylids, is that right? The chewing surface seemed kinda like a camelid tooth. Also... there appears to be another stylid on the side of the tooth not down the center like I've seen. It's a much smaller one. Is that normal? Was looking at other pictures online of stylids and didn't see one on the side like this. I do believe it has some age to it. Not sure how old tho. Size is 33 mm across or 1.3". Size is 51 mm front to back or 2" Found on a river gravel bank here in SE Texas where I find Pleistocene material.

Out on the river gravel banks I always pick up the unusual. I pass up clam shells regularly and we do have oyster shells nearby on the Gulf beaches south of me. I thought this was weird and out of place... so I kept it. What is it??? I doubt it came upstream to my location so it had to have been washed down from further up north. I didn't measure it but if it needs a measurement I'll get it. Also, sorry for the color differences... I brought it closer to the light in the handheld images. Found in SE Texas on a river gravel bed where I do find Pleistocene material.

I found this tooth fragment today which I think might belong to Equus. I don't think it belongs to anything else... but I hadn't seen a horse tooth fragment where these lines were visible that run the length of it. They probably are in each of them... I just hadn't seen it so wanted to confirm with those who know. It's too busted for a chewing surface view. Almost no chewing surface available as it's kinda thin. Length is 2.3"

Also found this bone the other day which I think is a camelid distal metatarsal? It's completely mineralized and would shatter if dropped. Very brittle. But I was wondering... does anyone feel as torn as I do when I try to clean these things up and you take off the matrix... the color underneath just doesn't match to what's been exposed for so long?? I do want to see the complete bone minus the matrix and crusty stuff... but dang the color difference bothers me. Oh well. So is it camelid? I did find one that seemed similar a while back. Sorry for the poor images. Included one where I was getting the clay material from between the condyles so the color differences can be seen. That crust is solid.

Here's another small bone that I found. I'm not sure if it's a metacarpal/metatarsal?? Some images online use the same image but both words. But it is a small one and I'm not sure if deer would be the owner. Could be... I'm just not aware that it could be that small. Size is 3/4 inches wide and 1.5 inches in length. It does have some mineralization to it. Found where I find Pleistocene material.

Was a good day today out hunting. River is receding leaving small gifts. Also saw the fattest and biggest water moccasin I'd ever seen on the gravel bank which was a bummer. After chasing him off I found this cool little point which is my 1st out here. But I also found this little bone that is either highly eroded and gave it this shape or it is that way. I can tell that the cracks are filled and the matrix along the bottom is gonna have to stay for a bit cause I'll end up breaking it if I scrape it with dental picks. It is brittle and appears old as other similar bones I've found here. But it was just unusual and thought I'd see if anyone might be able to tell if it's eroded into that shape or the bone is in fact not far from its original. It's 3/4 inches wide and 1.75 in length. Sorry for the hand held pics just wanted it closer. Found on a gravel bank here in SE Texas.

Found a pair of bones (I think) this morning. They look like bones and my 1st thought was perhaps toe bones or phalanges. They are mineralized...the larger one completely. Then I couldn't really find a match online so I started thinking it was similar in appearance to mosasaur verts I see them find online up in the NSR. But that's way up there in SE Texas speak. But then I thought perhaps it's wood. So I'm confused. Every vertebra found so far has had a spinous process or a part where it was obvious one belonged or some other part. These are simple. Tail bone? The larger we can call #1 is 1.8 inches or 47 mm in length. Smaller #2 is 1 inch or 26 mm in length. Smaller has more of a 90 degree angle to it edge whereas the larger has a 45 degree angle. Smaller definitely has wear. Thanks.

Found this today in a spot I usually find Pleistocene material. I have no idea if it's a tooth, part of a tooth, or it has something to do with perhaps a turtle shell or fish??? Thanks for any help. It's 1.25 inches in length and .75 inches wide.

Found this small toe bone (phalanx) today in an area where I find a bunch of Pleistocene mammal bones. It is rock solid. Heavily mineralized. Unfortunately, the business ends are eroded and worn. Hopefully these photos will help with an ID. It is 50 mm or 1.99 inches from end to end. Thanks.

This small piece is 1.5 inches in length. I initially thought it was just some sort of concretion... but after looking at it closely, I'm not so sure it is. Under what I believe is an enamel or dentin there are these rings that seem to be consistent throughout. Even underneath at the bottom and inside there seems to be dentin. I believe there are lines (transverse?) on the edges as well or perhaps they are scratches. Anyone have any idea? It's pretty cool whatever it is. Also, the river does put a lot of wear and tear on other teeth and bones I've found.
