Fighting a sinus infection but made it out to the river today for a brief look. Southeast Texas gravel bar. Mostly Pleistocene, but older fossils are theoretically possible from exposures up river. Didn't find much since the river is up, but my most interesting find was this jaw fragment with some teeth intact. Since the biting surfaces are so worn, I'm having trouble with an ID. Is it possible to ID this based on tooth size/shape/location in the jaw? Or to at least narrow it down more so I can refine what type of teeth I should be comparing it to? Thanks. --Brandy

Hey all This has popped up on a local auction site, I have a couple of Enchodus fangs and a caudal fin in my collection and this jaw section would be a nice addition - if it passes the scrutiny of the experts! Is it Enchodus? Can you spot any repairs? I would assume based on the very fragile nature of the jawbone this is in the original matrix? The ad doesn't have much detail - I've added the only 2 pics supplied --------------------- Enchodus partial jaw fossil from Khourigba, Morocco, North Africa. Upper Cretaceous Period - 90 Million Years Old. Jaw itself is 5cm in length. --------------------

Some more Moroccan unknowns
Earendil posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi again! If you saw my thread from yesterday, you'll know I bought some Moroccan fossils for dirt cheap that turned out to be pretty nice. I went to the same dealer today and bought three more for the same price. I suppose I will start with the worst (most suspicious) first: I saw this vertebra and liked how it looked, so I bought it. I'm totally fine with spending $20 for a vert recreation, too, so no big deal if it's fake. What makes me suspicious is the place where it's chipped, it looked like there was paint flaking off. I guess I'm asking, how much of it is real and what is it supposed to be an imitation of? Okay, next is a Globidens tooth and root in matrix. A little beat up, but still cool: Lastly, a weird jaw that I have no clue about. Like I said, I'm not a vertebrate guy. One of the teeth is banged up and looks repaired, but I thought it was cool anyway: Well guys, thanks for looking, I hope you'll find them as interesting as I did! And I said I'd tag @pachy-pleuro-whatnot-odon, maybe you can help. -

I just returned from a dig near Baker, Montana. I found this part of an Edmontosaurus jaw with the teeth replaced by siderite. I thought it was a rare replacement. If important, the KT boundary was very visible on this ranch. The section is about 3 inches by 3 inches.

This fossil is listed as a Baryonyx tooth with possible jaw underneath. What do members here make of it? Is it possible to tell whether it's a jaw or not alongside the tooth? Formation: Wealden formation, Hastings.

Another Mosasaur jaw real or fake!? Or somewhere in-between?
PhishermanPhil posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi there! I'm new to the forum. I recently picked up a mosasaur jaw, my first fossil. Question is it real or fake, I started doing the research after making the purchase.. Comparing it to other examples, it's somewhere in the middle. It doesn't look totally manufactured, but it also kind of looks to good to be true. Opinions? -
I have never found a jaw like this. The only thing I can find that is similar is tapir which would be pretty rare for this area. Found in south central South Dakota. Miocene

Real triceratops bones? Or not?
Josesaurus rex posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello everyone, I would like to know if someone can help me identify if precisely these remains correspond to triceratops, or to some indeterminate ceratopsian at least. They all say they are from the Lance Formation, with no county, state, or anything. They are different types of bone, which I will detail below. 1. Sect of the jaw 2. Section of the upper jaw 3. Mandibular sect 4. Ungual, foot claw I await your comments, and thank you very much in advance.- 5 replies

This past Monday, during an outing to a quarry with Dave Broussard, our very own Tim (Fossildude19) and Paul (Paul1719) in PA. I found a partial ischnacanthid fish jaw. As it was only the second known from that location I donated it to Dave for study. A few moments later Paul found one too! He also donated his. It was interesting and enlightening watching a professional photograph and preserve it before removing the part of the slab it was in. Dave is a professor at Lycoming College in PA. and a vertebrate paleontologist. Ischnacanthids had a primitive arrangement when it came to teeth (though some argue it was more advanced than we give it credit for.) The teeth were a part of the jaw, though still made from the dentin bone material in the jaw. They did not appear to be able to regrow them as far as we know. This specimen has two partial teeth and one complete one. Im hoping to read Dave's research on the subject when he publishes it. The photo is courtesy of and copyrighted Dave Broussard. *I accidentally put Acanthodians had a primitive arrangement..I meant ischnacanthids ( a type of acanthodian.)

Found this in Travis County Texas Creekbed area. Looks like three teeth set in a jaw (left side upper area, one slanted one broken off, one full). From Cretaceous area. Lots of Arietina (small curly snail) fossils uphill from area. Any ideas?

Sorting through material from 4 weeks back. I have never found any Meg fragments at this location. I have found Isurus oxyrinchus, along with other Makos and Great Whites. This one is 11 mm And then ... this 29 mm fish jaw. I find alveoli placement rather odd. Does anyone know of any similar fish jaw? Thanks Jack

Hi All, About 3", this was found by a friend this weekend by the Cape Fear River. We're guessing a jaw of some herbivore, but no clue beyond that! Anyone know? Thanks!

I found this front bit of carnivore jaw while out on my latest fossil collecting trip in the White River Formation of Colorado. Only one tooth is complete, the canine tooth has broken off. It’s too large to be Hesperocyon and the cross section of the canine tooth does not match that of Daphoenus, which I have previously collected material, including a canine tooth, from. That leaves Hyaenodon and the Nimravids. After doing some comparative research with pictures of skulls, I am tentatively leaning towards this being from a Nimravid, as the contours of the jaw line near the socket where the canine tooth sits are fairly distinctive and match those in the pictures of Nimravid skulls almost perfectly, less so than the contours seen in the skull of Hyaenodon horridus. Plus, the canine tooth is triangular in cross section, and though I couldn’t find any specific references on this bit of anatomy that makes more sense to me for the stabbing canines of a Nimravid rather than the flatter canines of Hyaenodon. But alas, here I am to get other opinions. Hyaenodon or Nimravid? Or something else entirely? (I am fairly confident this isn’t just a piece of oreodont jaw, haha). Thanks in advance.

Found this fossil while surface collecting in the Alberta Badlands (Canada) North Of Drumheller in the Red Deer river valley. Looking for some help to ID this unusual looking fossil. If I had to guess I'd say it looks like a possible jaw fragment? Any help to ID would be greatly appreciated. Thank you in advance.

Prepping some White River Fossils - Guidance and advice needed!
Opabinia Blues posted a topic in Fossil Preparation
I have a few really nice fossils from the White River Formation of northeastern Colorado that I need to prep, and given I am a beginner at fossil prep I would really like to gain some advice and guidance from people with experience do I don’t accidentally damage the fossils. The first fossil is an Oreodont skull. The skull is mostly intact, and I was able to extract it from the field without using any glue or stabilizer or consolidant or anything like that, so this fossil is in its “natural state.” The zygomatic arch and upper tooth row are crumbling, but otherwise everything else that I can see is there appears to be stable. The other side of the skull appears to be still mostly encased in matrix, and is likely to be better preserved. What’s everyone’s opinion on whether or not I should apply penetrant stabilizer directly to the bone before prepping to help keep it intact? The second fossil is a jaw bone, tentatively identified by me as Subhyracodon but I will need to reveal the teeth to know for sure. There are several large cracks throughout the bone (as can be seen) but the entire bone is still in one piece due to application of PaleoBond penetrant stabilizer in the field. There is matrix in between the larger cracks, I imagine I will have to pull it apart one piece at a time, clean the pieces, and then glue them back together. I don’t have any specific questions at this point other than about the overall process. It would be great if those with experience could briefly go over how they would go about prepping these fossils would be great. Is there anything I should avoid, be careful of, or watch out for? Equipment I have includes an air scribe with compressor, dental picks/tools, and the full suite of PaleoBond glues and stabilizers, including the debonding solvent. Thanks in advance! *These fossils were collected legally on privately held land in Weld County, Colorado, with full landowner knowledge and permission.- 4 replies

I have some Gansu fossils from the Linxia Basin, but I wasn't 100% sure on ID. The teeth were sold as Entelodont molars, and my current assumption is that they belong to Paraentelodon macrognathus from the Oligocene deposits in the Linxia Basin. From what I've read, they are similar to Daeodon, at least size wise. I think the formation would be the Jiaozigou Formation? But I'm not entirely sure. The Chleuastochoerus jaw, i have no idea. I think there are 2 species present in the Linxia Basin, and I don't know if it's possible to ID them down to species level without more specific provenance. That said, I honestly don't know anything about this animal, aside from it being a prehistoric pig. I know the fang had some glue on it when I put some acetone on it during prep, so it's probably repaired. The back side had big globs of glue that turned pretty nasty in acetone, but fortunately, there was nothing on the jaw itself, and I easily dug the teeth hidden inside the matrix. Not really sure if I did a great job though since I don't prep that often.
