I've had some free time this weekend, so I decided to mix things up and try hunting the Brazos instead of the usual cretaceous formations around Austin and DFW. The Pleistocene period is something I've always been fascinated by (probably due to the Ice Age movies), so the long drive wasn't enough to dissuade me. The weather was just right which made a day by the river all the better. This being my first time at the Brazos, I was a bit unfamiliar with the geography/prime hunting locations. I settled on parking by a bridge and decided to spend my day checking out both sides of the river. Navigating my way to the water was more treacherous than I was expecting and I wound up having a close encounter with a black snake that may have been a cottonmouth. The sandbars were unfortunately mostly sand. However, dotted about here and there were patches of gravel. Most of my day I saw footprints all around me so I knew I was definitely not the first person to have hit up the spot. The first 4/5 of the day was a bit slow. I found the occasional piece of bone or turtle, but nothing too exciting. Only until the final hour of daylight did I reach a distant area of the sandbar (about a mile from my car) that began yielding some cool specimens. I didn't get a chance to study them closely until I was home because things got dark very quickly! Being alone at the dark river gave off spooky vibes so I ran a good portion of the distance back (with my fossils in pocket which was a bad idea). Thankfully, I made it back without any major disasters and I've since had some time to rest and take a closer look at my finds. Below are pictures of my most interesting finds that I would like to learn more about. All in all, I'd say the trip was a unique experience and worth the time! Overview of my favorite finds: ' Each item and some closeups: A: Definitely a horse tooth. Parts of it are missing. It may just be wishful thinking, but I think it could be from a three-toed horse? There are Miocene and Pliocene deposits upriver so I suppose it's a possibility. B: A couple of my favorite turtle shell fragments from the many I picked up. Unfortunately that small crack on the flat piece caused it to break in half right after I snapped my pics. Guess that happened because I ran with it in my pocket... oops. C: Looks like an old bison tooth to me. D: Not sure what this is. Could it be mammoth enamel? E: I think it's a scute possibly from an alligator. F: Looks to be a part of a tooth. Bovid would be my guess. I: This one is the strangest of the bunch in my opinion. Looks like tooth material, but it's hard to say. In the first closeup, I notice that there are bands run across the piece in a consistent pattern. Let me know if they are any closeups you would like for me to upload! Thanks for reading.

Greetings again Thisis a second vertebra also found at the Lee Creek Mine (aka Aurora) in Yorktown spoils. It is 50mm in length, rather porous and very light. I was thinking bird, but thought I'd get some other opinions. Any ID suggestions? The photos in order are: "bottom", "top", "side", end 1 and end 2

Greetings, Since There's not much collecting to be done here, I've started diving into the collection and trying to ID and label. I found this vertebra at the Lee Creek Mine (aka Aurora) in Yorktown spoils. It is 33mm in length, rather porous and very light. I was thinking bird, but thought I'd get some other opinions. Any ID suggestions? The photos in order are: "bottom", "top", "side", end 1 and end 2

I just posted some colorful small shark teeth I found yesterday, but also went out Saturday. I had a number of finds which were small and I was not certain of their identification... 1) An Epiphysis, which I think is a long bone "cap" for a juvenile mammal. Which bone? 2.) A possible claw... Could this be bear ? 3) Looks like a Carpal or Tarsal, but not one that I have seen. VERY light in weight. 4) An odd Alligator or Crocodile Osteoderm. On the left of the 2nd photo, there is a flat section on the left edge, and then the increased slope to the center. possibly imagination, but it seems different from the average gator osteoderm. 5) Finally , a very small fossil and definitely unknown to me Any comments and suggestions greatly appreciated...

I went out hunting the Peace River yesterday. Spent a couple of hours with so-so results and because I was close to a favored location that has always been more Pliocene (lots of marine), than Pleistocene (few/no mammal fossils), I decided to spend 3 hours there. It's primary attraction are small pretty shark teeth. On the right are morning finds and on the left, one of my favorite hunting locations. On the left are dugong rib fossils, very dense, and not the typical Peace River black color. So , Let walk thru some of the many finds. I love the tiny upper Hemi teeth.. and especially when they are yellow !!!.. a relatively rare color, especially in the river. Next up are a Crocodile tooth (?) and something that looks like a claw, but is more likely a broken lower hemi. Here is a better photo of the croc tooth sitting on a piece of dugong rib. . and a better photo of the broken lower Hemi.... I have found fragments of megs here and one whole Meg, ray teeth, pufferfish mouthplate, sea urchin spines, Hemis, a few Makos, Galeocerdo cuvier tigers, but not aduncus or contortus. This spot has a very narrow range of fauna fossils. Always interesting , always relaxing.

Good afternoon, I found this item while fossil hunting at Onslow Beach located in Jacksonville, North Carolina. It seems to have 3 tooth sockets, two relatively close together and the single socket located more forward on the specimen. Is this part of a jaw bone or has my imagination run wild? The mat is showing inches so appx 4.5 inches by 3 inches. Thank you very much for any assistance in ID the item.

Hi everyone! I’m having trouble to identify these shells. Is there an expert that could help me? Thanks in advance Pliocene, South of France (Ruler is in centimeters)

I do not recognize this one.... Where is @Harry Pristis when I need him? I heard that canids ALSO have tarsals and carpals.. What else besides Bison, horse, camels ??

Hi, Can someone please guide me in the ID of these shells? Zanclean from south of France The one on the right is what I commonly find. Left one is huge versus what I usually find. Middle one has a different form factor, very pyramidal. I assume one of them is Astraea rugosa but not sure which one and what are the other ones. Thanks! Etienne

hi all, I purchased a handful of Pliocene shark teeth from Indonesia recently, and the seller included the attached tooth. I'm assuming that it is mammal incisor?. The fauna includes both marine and terrestrial mammal teeth. The enamel preservation is consistent with stegodont and hippo teeth that I have purchased from him. The scale is in cm. Any ideas?

Hey guys new to the forums and thought I’d make a post to have you guys help identify some possible fossils that i found in a local creek after heavy rains.There are lots of mission era ranches so there is a possibility of them being old but not fossilized cow bones. Let me know what you guys think

Weather was cold and windy yesterday, but sunny and calmer down in southeast Texas. Sandy gravel matrix. I always hate to get my hopes up too early in the game, but I think I may have found my first 3 toed horse tooth. I looked at Hulbert's Fossil Vertebrates of Florida book. Photograph D on pg. 292 is a right m1 or m2 from nannippus aztecus. It appears pretty similar, but I'm not sure about size. Nannippus Aztecus would have been in Texas from late Miocene to Pliocene, so region would fit. And I think @garyc has found a nannippus on the Brazos before in this general region. My husband and I weren't able to take very good pictures of measurements of the occlusal surface without sacrificing accuracy. Gave up on trying to photograph it with the ruler and got better results. MSCH, from root to parastyle: 36mm APL, length of crown enamel: 18 mm TRW, width of crown from mesostyle to posterior protocone: 16mm. @Shellseeker @Harry Pristis @garyc

I received some matrix from @sixgill pete a while back in a TFF auction and picked most of it a while back and ID'd the bulk of the teeth and other material. Lately I have been going back through some of my sharks teeth and looking more closely at items I was unsure of These three teeth are one such group out of this matrix. I have read Purdy et, al (2001) a bunch of times, looked at elasmo.com for hours on end, read dozens of threads on here and am still a bit confused/uncertain. So, I figured why no just ask and get several more opinions, I always appreciate what folks here have to offer. The teeth are shown in the pictures below and it is mostly the big (relatively speaking) one (#1) I am most interested in. The two smaller ones (#2 and #3) are fairly similar looking although #3 is much more worn, and are likely small symphysial teeth from ???. Tooth #1 is 7.4mm tall and about the same width. My first guess (wish?) was a Megachasma even though I know these are extremely rare out of the Lee Creek material. It sits very flat on it's broad base and the crown is slightly curved lingually, but not as much as many depictions of this genus. There are no serrations on the crown, but it is somewhat worn and the tip is missing, so that could factor in. I have looked at all the various posts on here of possible Megachasma's, most of which are probably not (more likely symphsials of any number of sharks) and looked at Don's Megachasma that Dr. Shimada confirmed and still was not 100% convinced one way of the other. This tooth does not look dissimilar to what is in Purdy or the description written there. Some of those crowns are not very "bent" either, nor is the specimen that Don posted very curved as far as I can tell. But then I see many posts by @MarcoSr and @Al Dente and others that show symphesial teeth from Hexanchus, Carcharhinus, Hemipristis and Galeocerdo that all bear similarities. So, I ask what you think and appreciate any and all insights that can be offered. And here are some close ups of the crowns on each of the teeth just in case that adds anything useful.

I found this in the Aurora Fossil Museum dig pits, so it’s likely Pungo River formation (Miocene), although there’s a chance it could be Yorktown formation (Pliocene). Any idea what it is? My best guess is some sort of jaw bone, maybe from a fish.
-
While not as big as my 2.03 inch one I found in 2019 it did come from the same site. So maybe there is another 2 incher there. This one measures 1.65 inches long along the slant and 1.43 inches wide.

Unknown bone(?) from Pliocene Pico Formation of Southern California
Crusty_Crab posted a topic in Fossil ID
This was found in the Pliocene marine Pico Formation of Southern California. I'm leaning towards a marine mammal but I'm not even sure if this is bone or part of an echinoid test.

Hello, I bought these fossils as Rotuloidea fimbriata, from the Pliocene of Morocco; yesterday I saw some photos of Heliophora orbicularis, and now I have doubts about what species they are. Any ideas? 1.- 2.- Thanks!

I am really sore today but it is always a great day when I find a GW because of their rarity in my hunting area. This is a small one at 33 mm. This was jet black on 1st sight, and seems to lighten as time passes. The "shape" of this tooth seems different to me. Does that allow some further insights on tooth position? There used to be some people trying to do tooth position based on shape for Megs, Makos, GWs.... The one on the right below seems to match:

With a little time, I am sorting November fossils. I found this jaw segment back in November. Seems like 3 of 4 teeth are snapped off at the root line. When I found it, I thought it might be alligator (short , round alveoli) but now I lean to dolphin. I am interested in whether any members who have seen broken dolphin teeth and jaw fossils in the Mid_atlantic coast recognize similarities. Thanks for looking. A while back, found another small jaw at this site, turned out to be dolphin. http://www.thefossilforum.com/index.php?/topic/115727-new-for-me/ Also just sharing another shell ?? with Botryoidal crystals out of the Peace River. I am finding quite a few of these. Guess it is my choice of locations. It does seem to be forming in an empty space in a shell.

I usually don't post the trip to POC anymore but this time there were some oddities i wanted to confirm and or see if anyone knows what they are. I found the usual few ptychodus teeth as well as tons of broken shark teeth but also some more rare items. There is one small shark vertebrae, a piece of a fish vert, two broken ends of sawfish rostral teeth, a weird piece that looks like coral to me but also looks like it has teeth poking out of it, a large piece of mammoth enamel, and what I believe is a small mosasaur tooth. Pictures 2, 3, and 4 are the mosasaur tooth. I have it in my hand for scale and it is small but it looks exactly like ones i have seen posted from the North Sulphur River just smaller than most. Pictures 5 and 6 are of the coral looking thing. I could have sworn i saw something like this on the forum before but i have looked and can't find the post. Any ideas of what this is? 1 2 3 4 5 6 7 8

Decided to head to a stream with my kayak on my day off recently. I frequently go to this site because it is not too far of a drive. This site gets collected a lot but it looked like no one had been there in a while. Without people walking over the site, small fossils start to be exposed. I crawled around for a couple hours and found many small fish bones and otoliths. Here are some photos. Lots of inarticulate brachiopods. Only two species found here. The round Discinisca and the lingulid Glottidia which is always broken. There is a Lepophidium (Cusk Eel) otolith above the Discinisca
