  1. Giant Tortoise Peripheral?

    Found this huge chunk of tortoise shell yesterday while scouting a new gravel bar on the Brazos River near Houston. I've found many fragments before, but never anything this large. What got me even more excited was how it seems that it's a mostly complete bone (except for some wear on one of the flat edges that would have been an area where the bone joined another piece of the shell). I tentatively identified it as a peripheral from the edge of the shell from a Hesperotestudo sp., since they seem to be the only species of giant tortoise that lived in Texas during the Pleistocene. Can anyone with better references than me confirm or deny this? Thanks for looking!
  2. Pleistocene Rib Head

    I've found many rib fragments on the Brazos River in the past, but they've never been substantial enough to attempt an ID. Yesterday my luck seemed to change. About all I know about this piece is that it's heavily mineralized and definitely the proximal "head" of a rib bone that would have articulated with the corresponding vertebra in life. I've found some pictures of horse and deer ribs online but they don't quite match. I'm trying not to get my hopes up too much, but the most similar bone I was able to find was from a Florida panther - so maybe carnivoran of some sort? As always, any help from the Texas and Florida fossil hunting veterans would be appreciated!
  3. Curious bone fragment

    Here’s a strange little fragment I found on the Brazos River. I’m not 100% sure it’s bone.... maybe wood. However, it has a different outer texture than I’m used to. Also, the inside appears to have two distinct chambers. I considered antler, but I’ve not seen a broken antler time that has these chambers inside.
  4. Hoof core

    I made it out to the Brazos River for a while on this beautiful, sunny day. The temps ranged from 49 to 71 with low humidity and virtually no wind......perfect! I found a hoof core that seems different from the horse hooves I’ve found. It’s a little beat up, but maybe someone will recognize it. I placed it next to another hoof core that Harry recently identified as tapir. The tapir is on the left and the hoof in question is on the right in each of the pics. @Harry Pristis @fossilus @Lorne Ledger @Shellseeker @GPayton
  5. Radioulna

    @GPayton recently posted a Pleistocene mammal radius that’s still waiting for a positive ID. I thought I’d try to get some info on mine as well. Mine does have the fused radius/ulna and what I learned in the latter thread is that fusion generally indicates artiodactyl. Mine seems to be in the size range of either camel or bison. Is there any way to tell the difference from the fragment I have here? @Harry Pristis @Lorne Ledger
  6. Canid jaw

    I found this jaw on the Brazos River a couple of years ago and figured that it is just from a modern dog. Just thought I would try to get a confirmation. I would hate to discount the idea that it is something more interesting like Pleistocene coyote or wolf. It is actually pretty well mineralized. The cancellous bone is hard and not spongy like other modern bones that I find. The carnassial measures 22.2mm x 11.9mm
  7. Assorted Pleistocene Vertebrae

    All three of these vertebrae were found in a single trip to the Brazos River several months ago. Although I know that they're likely mammalian, the closest to an ID I've been able to get for any of them is Equus sp. cervical vertebra for the largest, and maybe thoracic vertebrae from a horse as well for the other two since they're so similar. Anybody able to help? Vertebrae 1, 2, and 3 (in order): Vertebra 1 (side view): Vertebra 2 (side view):
  8. Mammoth Radius?

    Found on the Brazos River several months ago. Although worn and incomplete, it seems like there's enough diagnostic features to make an identifcation possible, at least in my mind. After searching the forum and the Internet for anything comparable, the closest match I was able to find was the proximal end of a mammoth radius - mostly because of the shape of the articular facet and the areas surrounding it. Obviously mammoth bones are huge, but from the pictures I've seen it looks like even though the radius itself is very long, it only broadens towards the distal end. Any help would be appreciated, even if it does mean calling me crazy!
  9. Three-Toed Horse Tooth

    I found this small lower tooth from a horse a couple weeks back on the Brazos River. Initially, I wrote it off as just another Equus sp. since horse teeth are probably the most common fossil in the Beaumont formation that I hunt in next to turtle shell fragments, but after looking at it again yesterday and comparing it to pictures in Hulbert's book on Floridian fossil vertebrates, I'm starting to rethink my earlier identification. For one, the design of the occlusal surface doesn't match those of ordinary Equus teeth. The tooth I have is an m3 I believe, and comparing it to examples of Equus m3's shows this discrepancy quite well. The tooth is also very small, despite the roots having been worn off a long time ago - the crown length is exactly 2 cm and its width is 0.5 cm. I know that pre-Equus horse fossils can be found in the Brazos now after just having an astragalus I found identified as such, and after seeing @Lorne Ledger's very nice upper molar from a Nannippus pulled from the same stretch of the Brazos that I hunt. It's definitely within the realm of possibility. Any help would be appreciated!
  10. Three-Toed Horse Astragalus?

    I found this perissodactyl astragalus on the Brazos River near Houston several months ago now. But after finding other fossil astragali that are similar, but much larger, from horses, I've started to question my initial identification of the small one as just another Equus sp. After finding some pictures online and comparing them with what I have, I'm starting to think that this astragalus might be from a three-toed horse, but what species I don't know. Texas was home to Nannippus, Calippus, and Cormohipparion during the latter half of the Cenozoic, but did any of the three-toed horses like these survive into the Pleistocene? I'm only asking because the formation I'm hunting is the Beaumont Clay, which is firmly in the Pleistocene range, and that would make the three-toed horse ID a little shaky. Anyone able to help me out?
  11. Horse Cannon Bone Question

    So I've been hitting the Brazos River pretty steadily all year for Pleistocene fossils, but aside from some astragali, the only perfectly complete bones I've been able to find are two Equus metacarpals ( cannon bones). I'm not sure if this post belongs in this section of the forum since I'm not really looking for an ID (unless I'm wrong and one of the bones isn't Equus after all), but instead wanted to ask a question about the bones' anatomy. That's because although they both look exactly the same and are both clearly cannon bones from what I'm positive are horses, they each have different lengths and widths. The distal faces are also both different - the skinnier cannon bone has a pitted face while the thicker, shorter cannon bone has a completely flat one. Right now my theory is that horses either have different length cannon bones in their fore vs their hind legs, or the two bones are from different aged horses, but I haven't been able to find anything helpful online. Anybody able to help me out? Are these bones from different species or is one of my two wild guesses actually right? And because I've appreciated their help so much in the past, I'll just give @Harry Pristis and @Shellseeker a heads up!
  12. Claw Core and Hoof Core?

    Happy Thanksgiving to everyone! I really appreciate this forum and the people willing to take the time and effort to answer everyone's questions and help people learn. I found these two fragments on the Brazos River in sandy gravel and low water near Brookshire, Texas. Mostly Pleistocene era here with some Cretaceous shells also I think. FRAGMENT ONE: CLAW CORE? The photos I'd seen of claw cores made me think this could be one, but since it's not very well defined, I've been wondering if it's even animal related at all. The most similar example I could find was a turtle claw core documented by @Harry Pristis , as seen here: Am I way off base? The flat smooth side and holes made me think it was vascular tissue, but I've wondered if it might be reef or even some type of mineral instead. FRAGMENT TWO: SMALL HOOF CORE? This looks like a very small hoof fragment with a rounded top and very flat bottom. The exterior looks worn on the toe-tip area and broken off toward the top. I had trouble finding anything that looked similar online. It does seem very small compared to several other hoof core examples I've seen. The closest thing I could find that looked a little similar was this camel hoof core fragment documented by @worthy 55 As usual, any help would be appreciated, and thanks to anyone who takes a look. --Brandy
  13. Help with Intact Bone ID

    My friend found this in the Brazos River riverbed with low water, sand and gravel. Near Brookshire, Texas. Mostly Pleistocene fossils here. This was our first time to find an actual intact bone, so we were really excited. No clue what it is though. The only thing I could find that I thought looked similar were calcaneus bones. Any help is appreciated! Thanks, --Brandy
  14. Brazos River Vertebra ID?

    Location: Brazos Riverbed, near Brookshire, Texas Estimated Age: Pleistocene Matrix: Sand, low water, gravel I found this vertebra in the riverbed yesterday and could use help identifying it, if possible. I found this link, which made me think it was possibly a turtle vertebra, since it looks like the front is convex and the back is concave. It's a pretty large vertebra, so my turtle guess may be completely off, unless this is another hesperotestudo piece. Thanks for any help or suggestions! --Brandy
  15. Brazos river scale/scute/bark???

    Hi everyone. Today I had this surface find on a Brazos River mound. Striated face looked like wood, but turned around and looked similar to bone(?). The cross section is whitish. [LxWxT] 1.250” x 0.500” x 0.125”. Could it be a scale/scute or actually wood? Thank you.
  16. Costal vs. Scute vs. Osteoderm IDs

    Location: Brazos River, near Brookshire, TX Found: Gravel, sand, low water Estimated time: Pleistocene I've been searching through info on scutes, osteoderms, reptile fossils, and types of turtle shell and plastron parts because we seem to have a lot of those in our area, but I'm having a hard time telling the difference. These are my best guesses, and I'm hoping someone can educate me on the differences. FRAG 1--I think this is a large turtle/tortoise scute fragment, but I'm not sure how to tell the difference between neural, costal, central, etc. FRAG 2--I believe this is an osteoderm (because it looks like skin instead of part of a shell?), but I'm not sure the type. Maybe alligator? FRAG 3--My husband thought this may just be a rock, but I thought it looked like a fossilized shell plate of a turtle. It's relatively thin. We see a lot of these on the river. FRAG 4--This looked like another osteoderm to me because it has a similar texture on top to Frag2. But it's much thinner and the edges are more defined. Any info would be a big help! Thank you. --Brandy
  17. Pleistocene Bone Identifications

    We found these bones laying in sandy gravel in a sandbar in the Brazos River near Brookshire, TX in an area that has Pleistocene mammals and reptiles. I've read threads that joke about chunkosaurs when there is too little bone to identify, and these may fit that bill! I know they don't have a lot of identifying characteristics. I'm hoping to at least rule out a few things or get a few possibilities. My young niece and nephew have come out with us some to look for fossils, and it would be neat to tell them a little bit about these since at their age they just think all fossils = dinosaur. :-) I'm also testing out editing the pictures to cut down the file size so that I can post more, so I apologize if that's a little messy. There are three different bone fragments with six pictures apiece. The first fragment was smaller than the others and darker. The second was the largest and had a sort of compressed oval shape. The third was a chunky more rounded bone. Thanks again for any help.
  18. Brazos River--Large Turtle Piece?

    I found this partially covered in sand and very shallow water at the edge of a sandbar in the Brazos River near Brookshire, Texas. I cleaned it up with vinegar and a toothbrush when I got home. The fossils in the river near me are supposed to mostly be Pleistocene, but I've also heard that there may be some Cretaceous period marine fossils. I tagged this as a possible turtle piece because that's what it resembled to me, but I couldn't really find anything like it when I searched the internet and this site. I have more pictures, including pictures from before I cleaned it, if those would be helpful. It weighs about a pound. Any information would be great. Thank you! --Brandy
  19. Brazos River Partial Mammoth Tooth?

    I recently got interested in fossil hunting when my family found a couple of fossils while wading in the Brazos River near our home. Everything my husband and I have found has been on a sandbar or in shallow water in the Brazos River near Brookshire, Texas. I've been told the river can be a good place to find Pleistocene fossils of big mammals and reptiles. We've found several things that I'm hoping people can help me identify in the next few days, but it may be easiest to start with one that doesn't require a lot of pictures so I can test out this whole submission process. =-) We found this and debated about what it was. It didn't look like normal petrified wood, and it resembled a mammoth tooth fragment I saw on this site. Any info would be great. I have more pictures if they would be helpful. I'm looking forward to posting a few partial bones we've found and some reptile-related things (unless I'm guessing completely wrong on those) in the next day or so. Thank you in advance. --Brandy
  20. Horse tooth

    I know these teeth are very difficult to identify. Based on its size I believe it is a lower tooth from a three toed horse. The crown is about 15.8mm. @Shellseeker @Harry Pristis
  21. Hoof core

    This looks like a very small hoof core of a horse. Any way to know if it’s from a baby horse, three toed Miocene horse or maybe even tapir?
  22. Osteoderm

    I’ve found several osteoderm of glyptodon and giant armadillo but this one seems a little different. Could it be sloth?
  23. 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!
  24. 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!
  25. 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.
