  1. Unknown Humerus

    I found this distal end of a mammalian humerus several weeks ago on the Brazos River southwest of Houston. After hours of searching, it doesn't seem to exactly match any of the common suspects: deer, camel, horse, or bison. Deer or camel is more likely than horse or bison, as the bone is relatively slender and the end of it isn't as bulky as either of those animals. It is possible that I have incorrectly ruled out deer and camels as the trochlea and capitulum on the end are very worn down. If anyone has any suggestions, I'm more than willing to hear them. Thanks!
  2. Perissodactyl Astragalus

    Both of these astragali were found on the Brazos River southwest of Houston. The larger of the two clearly belongs to Equus, but the smaller one continues to stump me. I know by the shape that it definitely some sort of perissodactyl, and although it resembles the shape of the Equus astragalus it is much, much smaller. The taller of the two ridges (I'm not sure what their name actually is) on the proximal end of the bone has been worn down by water or time so that it seems almost level with the other. If it were still present, these two astragalus would probably be identical. It occurred to me last week while looking at it again that it might be from a three-toed horse since they were a lot smaller than the more modern species of horses that prevailed in the late Pleistocene. Is there any way to tell? Or is it just from a younger Equus individual? Thanks for the help!
  3. Mammal Calcaneum

    Found on the Brazos River just southwest of Houston. I know this is the distal end of a calcaneum, but I can't figure out whether it's horse, bison, or even bear - it seems to both match and not match pictures I'm finding online. Any help is appreciated.
  4. Big rock covered with round nodules?

    Ran across this rock on the Brazos River near College Station, Texas. Covered with round nodules. Dimensions are about three feet by two feet by 18 inches. Any ideas what it is?
  5. Osteoderm?

    Found on the Brazos River southwest of Houston, Texas. I originally thought that this was an alligator osteoderm, but it lacks the distinctive boss in the middle of the bone. Looking around on the forum, it seems to match tortoise osteoderms rather well. Can someone confirm? I've found carapace fragments from both hard and softshell turtles before, but never one of these. I didn't even realize tortoises had osteoderms until now. What part of the body do they come from? As you can tell from the pictures, the bone is a decent size, so would this have to be a giant land tortoise or something else. Honestly, I'm pretty out of my depth with this one. Also, if someone could recommend any sort of books I can use to help identify the Pleistocene fossils I find in Texas, that would be appreciated as well - it's starting to seem like the Florida guidebooks on the subject are going to be the closest I can get!
  6. Mammoth/Mastodon Toe Bone?

    Found on the Brazos River just southwest of Houston. When I first picked this up, judging by the extreme river damage it had suffered being tossed around in the water for so many years, I simply assumed it was just another unidentifiable piece of Pleistocene bone to get thrown in the box with the others back at home. But since I've been going through the galleries of some of the members here to help identify the other bones I collected, this one seems to bear a resemblance to a mammoth metacarpal. Maybe the smallest one, although the damage on several spots is significant - the outer bony surface on one side has been completely removed. Am I just crazy, or is this thing the real deal? Any help on an ID is appreciated!
  7. Turtle/Tortoise Carapace Fragment

    Found on the Brazos River just southwest of Houston. The title says it all, as that's about all I know about this one! Any help on narrowing it down beyond that to something like a basic genus or even a species would be welcome.
  8. Mystery Jawbone

    Found on the Brazos River just southwest of Houston. When I first saw it I almost left it behind as it looked modern at a glance. The jawbone is definitely mineralized, however, but unfortunately its missing the teeth it used to contain as it's only one side of the whole bone. My best guess is that its a fragment of an alligator jaw based on the round tooth cavities and the way they're spaced apart, but if anyone more knowledgable then me could give a suggestion, that would be great.
  9. Peccary Molar?

    Found on the Brazos River just southwest of Houston. Unfortunately all that's left of this tooth are the roots. Judging by their coloration and the general size they seem to match up fairly well with pictures of peccary molars I've been able to find online. Obviously if there was an occlusal surface this would be a lot easier, but if anybody has any suggestions I would greatly appreciate them. Thanks!
  10. Turtle Nuchal Bone

    Found on the Brazos River just southwest of Houston. I'm fairly confident that this is a nuchal bone, but I my real interest lies in identifying what species of turtle it is from. I seem to remember reading a post on here mentioning that nucal bones are diagnostic to taxon, so that should make it easy. Unfortunately, I can't find anything anywhere about different Texas Pleistocene turtle species. Hopefully someone here is more knowledgable than me! I would appreciate any suggestions.
  11. Pleistocene Tooth

    Found on the Brazos River just west of Richmond, Texas. My best guess is Equus sp. judging by how flat it is, but any confirmations or other suggestions are welcome. Unfortunately the occlusal surface is extremely worn down, so identification may be difficult. If anyone knows exactly what tooth it is (such as location in the mouth) that would be very helpful too. Thanks for looking!
  12. Brazos River Pleistocene Bone

    Found this big chunk of bone on one of the gravel bars in the Brazos last week while the water was still low enough to walk around. I have a strong suspicion that it's part of the proximal end of a bison metacarpal, as that's the only thing that it seems to resemble in pictures I've compared it to online, but if someone more knowledgable in these things than myself could confirm (or completely disprove me, that's welcome too!) that would be great.
  13. Texas Pleistocene Rib Bones

    I was searching the gravel bars in the Brazos River just southeast of Houston almost every day last week before the storm hit this weekend. Now the water's too high to look, but I found a pretty good assortment of fossilized Pleistocene aged bones during my trips. Most of what I've found have been fragments that are totally unidentifiable, but a handful still have some significant features that could lead to an ID. These two are both rib bones, but that's about all I know. The first one I initially thought was from a modern cow due to how clean it was, but after picking it up it was clear that it's definitely a fossil - it's mineralized all the way through and has a decent weight to it. The only animals of that size that could produce such a large rib that I can think of off the top of my head would be either bison or hoses. The second bone also looks like a rib, but a lot smaller than the first. It has two deep grooves on either side that seem to match up with pictures I've seen of the origin point in deer and horse ribs where the bone begins to branch away from the vertebral column. As always, any help would be appreciated!
  14. Southeast Texas Pleistocene Bones

    I've been searching the gravel bars in the Brazos almost every day this week while the water is still low enough to get down there, and I've collected a pretty good assortment of fossilized bones. Most of what I've found have been fragments that are totally unidentifiable, but a handful still have some significant features that could lead to an ID. There's too many pictures to post all at once, so I'll reply a couple times with more. Thanks for the help! This first find is definitely a tooth and is the only piece I have that isn't from the Brazos, instead I picked it up on a trip to one of the small beaches north of the Texas City dike. I'm thinking bison, but I'm open to suggestions.
  15. Brazos River Mammoth Tooth Fragment?

    Another find today from the Brazos River just southwest of Houston. The grooves on top of this piece look very similar to pictures of mammoth teeth that I have seen before, but it is obviously far too small to be a full tooth or even half of one. Is it just a fragment? And is it even really a mammoth tooth? If it's a pseudofossil after all, it's a darn convincing one. It's definitely mineralized and has a crystal-like sheen with slight sparkles here and there when it catches the light. Any help on an ID would be great!
  16. Brazos River Bison/Horse Jaw

    Found these two teeth still attached to a segment of jawbone on the Brazos River just southwest of Houston today. They're definitely mineralized, so I believe I can rule out ordinary cows. However, after doing some research online the teeth seem to be much too flat to be bison, so maybe horse? They both look like molars, although one of the roots is broken off of the first tooth - I honestly have no idea how it managed to hang on for so long. Either way, I was incredibly excited to find this, especially after braving the 90 degree plus heat for several hours without sunscreen. Any help on an ID would be much appreciated. Thank you!
  17. Brazos River Pleistocene Find

    I was walking the Brazos River just southwest of Houston today since the water level is low enough to expose a good amount of gravel bars. Didn't find much until I finally found a spot to turn around and head back at when I spotted this bone poking out of the sand. I know that most of the Pleistocene age fossils in the Brazos aren't old enough to be mineralized, but this one definitely is - it's nice and solid. The part sticking out of the sand is white and the bottom is a little darker, kind of a brownish color. It might not be all that clear in the pictures, but there's a rounded groove on the "bottom" side that looks like it could have been the location of a ball and socket joint in the past. There's also some sand-like accretions on the edge of the bone containing some small pieces of gravel. I've always heard of people finding mammoth teeth and sloth bones on the river after hurricanes or big storms but have never had much luck myself. Thankfully it seems like that's changed! Any help on an ID would be much appreciated.
  18. Bone marrow crystallization? Or...pet wood?

    Hi everyone! We made another trip to the Brazos River off I10 in Texas a few days ago. One can find bones etc from the Pleistocene there. The water was up a bit, but we still found some interesting items. The most interesting thing we found was this fragment, it is kind of flat, I keep thinking rib bone. What is super interesting is what would be the interior (if it were marrow). It is white, and seems to have veins running through it. Have any of you seen anything like this, and is it possible that during fossilization crystals filled in the marrow part and that may be the original structure? Or - is it something else that I don't know of? Photo attached. And thanks!
  19. Mammal rib

    I know rib bones are very difficult to identify. So I hope someone is up for the challenge. My best guess is deer. Brazos river find.
  20. odd pebble

    at first glance this small stone looks to have an impression in it the thing is the stone is smooth to the touch I found this stone in the drive did not have a ruler with me or a coin so you may have to judge its size by my finger found in driveway gravel from Brazos river west of Houston Texas.
  21. 2 small artiodactyl teeth

    I was browsing through some past finds and came across these 2 teeth that I had placed with deer material. Just wondering if there’s any chance that these are actually llama teeth?
  22. Proximal tibia

    I hope there’s enough of this piece to correctly identify. It looks like a proximal tibia of something large like bison, horse, camel or maybe tapir? @Harry Pristis,
  23. Went looking at gravel bars today on the Brazos River west of Houston. Got lots of great pieces of petrified wood, and these which I can’t identify. This was only my second time looking for fossils so still working on identifying things. Any help would be greatly appreciated!!
  24. Weird pet wood?

    found in a gravel load in west houston from brazos river is this pet wood?....on the end it looks odd {first pic} the so called grain don't look right. could this be something else??
  25. vomit??

    is this some sort of vomit?? or something else? it is actually lighter than stone would be and gives me the idea more of plant material than bones or shell...perhaps some sort of bamboo plant like shoots and ground material?? last two pics are of a petrified piece of a bamboo like plant also found in same vicinity. found in gravel load from Brazos river west of Houston Texas.
