As it looks like I won't be able to make it back out to Charleston for quite a while, I was wondering what the fossil hunting scene looks like here in Texas. I've heard that there's some miocene material to be had around Galveston and Bolivar, and I've heard about the Eagle Ford Formation and Post Oak Creek, but I haven't come across a whole lot of information. I do know there are some invertebrate fossils along the Brazos, but I'm not super big on snails. I'm in the Houston area, so a day trip down to the coast is definitely feasible, but I need to do some more research before I commit to mak

I found this broken end of a long bone several months ago near Houston in the late Pleistocene gravel deposits of the Beaumont and Lissie Formations. Here are some pictures (with each grid on the graphing paper being 1/4 of an inch): I know that it's the end of a tibia because the grooves on the end are shaped to match an astragalus (ankle bone), and that their slanted angle indicates a perissodactyl like a horse, tapir, or rhino rather than an artiodactyl like a bison, pig, deer, or camel. Based on the size of the bone, I think I can pretty easily r

Hey everybody! I've got two bones that I'm looking to ID, and unfortunately neither of them are complete. However, the good news is that they both have enough diagnostic features that I'm optimistic an ID can be made. Here's the first: This first one is a partial limb bone that I found in a river southwest of Houston. The sediments that make up the river bed are from the Beaumont and Lissie Formations and are predominantly Pleistocene in age (although there is the occasional Pliocene/Miocene material that washes down from further upriver).

The partial repaired jaw was donated to a geological organization in Phoenix. I thought that I would try to ID it before giving it away probably to a young fossil enthusiast. No provenance is known. Is this an oreodont? Any idea where it came from? First photo of entire rock has a field of view of 4 inches. The second of the teeth is 2.25 inches for a field of view. Thanks, John

Hello, Heres another chunk of interesting-looking bone for which curiosity has finally gotten the best of me. This is a piece I picked up in 2021 on my summer dig at the Hell Creek Formation in Montana. I feel there’s a chance this piece might be identifiable. This piece of bone is bowl-shaped with a strange web-like texturing on the convex side. The edge of the bone which is not broken is rounded and almost flower petal like. There is a set of T-shaped rounded ridges on the concave side. Not the best quality bone either, with significant siderite encrustation being pre

Texas Pleistocene Brazos River Vertebrate Fossil from Fort Bend County
CDiggs posted a topic in Fossil ID
Hi Fossil Forum! I'm hoping for a little help in identifying a fossil I found recently in the Brazos River in Fort Bend County TX. I've tentatively identified it as Pleistocene in age (it's pretty well mineralized) and most likely belonging to a vertebrate mammal but have been rather stumped beyond that. I was initially thinking it could be part of a scapula but I'm now fairly sure its not. At one point I compared it to a skeletal mount of a Pleistocene camel at a local Natural Science museum and was momentarily convinced it was part of the ilium with part of the acetabulum damaged- 2 replies

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!

Going through Permian matrix. We have found many teeth and other identifiable microfossils. I have also found many of these metallic looking dark rocks. Are they bone fragments, or partially melted rocks? Thank you.
-
Hello, I recently visited a Permian site near Waurika Pond and collected microfossils for my students to explore back in the classroom. Is there a guide to identifying these fossils out there somewhere or is piecemeal searching here the way to go. If not, I will be making the one page guide over the summer have it to offer. Any help on something simple for my elementary aged students would be much appreciated. IMG_0064.DNG IMG_0065.DNG

Just acquired this associated fish vertebrate, the size of the rock behind this is about 28 cm, and that site produces a lot of megalodon teeth so I think it’s a Miocene fish. I'm not sure if it's identifiable by the vertebrae alone.

Need the Teeth Experts, Peace River, Small Vertebrate Teeth ID help needed.
Bone Daddy posted a topic in Fossil ID
Hi Folks, Lately I have been finding a lot of small teeth in my sifter. Most are damaged and that doesn't help trying to ID them. I lack a reference collection and the necessary books to compare these to, so I am asking for some help from our resident Peace River and vertebrate experts. My photos aren't the best and I know that doesn't help, but I did my best with my dated camera and hand tremors. I have numbered the teeth in the photos and will provide notes for them below : 1) This is a complete tooth and a very attractive little guy. 2) This- 10 replies

Hi everyone! I have no idea what this is. I looked up various scapulas and hip bones from various things (mostly reptiles) and could not find a match. It gets weirder though, while this one is from North Florida I have another almost identical one from the Moroccan Kem Kem! This piece measures 7.5 cm/2.95 inches long. The "fan" is 5.2 cm/ 2.05 inches wide. The base is 2.6 x 2 cm/ 1.02 x .79 inches. I'll try and get some pics of the Moroccan one but it broke and I have to fix it. What do ya'll think?
