My wife found this jaw bone on a river sand bar in central Iowa last fall. I think it is a sloth jaw but not certain. The smallish size is what gives me a little bit of doubt. I have not found anything else other than a sloth that fits. Am I missing something? Thank you!

I recently bought a lot of 3 unidentified dinosaur "bones" from Isle Of Wight. But one of them have got me in a bit of a pickle. There's not really any cell structure present anywhere, except from one small spot that seems to have some. Which makes me suspect it's wood. But the overall structure of this piece is really puzzling, because it looks like there are sockets or roots from a jaw in it. I hope someone with more knowledge about IoW fossils can maybe explain what this is.

Likely Xericeps Pterosaur jaw fragment from the Kem Kem Beds
msantix posted a topic in Member Collections
Recently i asked an expert about a Pterosaur beak fragment i bought a couple of years ago (along with other Kem Kem bones) and i sort of assumed originally that it was a rare jaw fragment of Alanqa Saharica, but after asking i was told it most likely belong to Xericeps - the other described Azhdarchoid Pterosaur from the Kem Kem Beds. I wanted to show it because i think it is a cool piece that is worth showing and is basically a highlight of my collection. It isn't perfect and it isn't complete (it is 8.5cm long) but it is a nice fossil and one i am very happy to have! Who knows, maybe it might help anyone else in the identification of Kem Kem Pterosaur jaws. Here is the holotype jaw of Xericeps that i have been comparing the fossil to... -
Is there any way to identify this jaw found in a freshwater creek in Virginia?
-
I'm not sure what this is. I have my speculations but that's all they are curious to see what you all think. It was found in Venice Florida around a lot of shell, tons of whale bones, manatee, very little sharks teeth, did find a lateral megladon tooth though. It has some curious ridges on it that's got me guessing and maybe the biggest clue. Excuse the gnarly fingers, I do art and construction. Thanks

Mosasaur Jaw - Real or fake
Righteous posted a topic in Is It Real? How to Recognize Fossil Fabrications
I see these on auction sites and wonder if there even real? Size average is 7”x5”x2” would be a nice display if real. Says they are from Morocco. -
I’d would love some help identifying what this is - I believe it’s a modern fish jaw of some kind but wouldn’t mind being persuaded that it’s a fossil! (Tooth Tap Test was inconclusive- sometimes glass, sometimes plastic) Since it’s likely modern, does anyone know what kind? 4 inches long exactly, about 1/4 inch at the widest point. Smooth on one flat side, a deep groove on the other. Wickedly sharp curvy teeth are part of the bone. Found at Purse on Sunday. -Our Fossil Group has conflicting ideas on this piece; catfish spine, gar jaw, snake mandible, bird spine... -It seems modern but it isn’t definite; there are certain parts that sound very fossilized where some sound very modern when tapped against a tooth. Thanks, FA

Hi I’m wondering what the Antorbital fossa is for in dinosaurs. I heard it could be part of muscle attachments or nasal passages. If so if a dinosaur has a big Antorbital fossa does it mean they have better nose or stronger jaw muscles. Thank you!!

I aquired this some time ago. Perhaps you guys can assist. Clearly it is a little jaw section. the length is 14cm. No sign of plaster, teeth do not appear to be set in separately and clearly no heavy restoration.Very little information on location unfortunately. It appears to to be some sort of Mosasaur. My guess at the time was a Prognatodon of some description. I am ready to be corrected on everything though.

Hello everyone! I just bought this fossil and I was wondering if it is real or if it has some kind of reconstruction since I know about all the fakes and composite pieces that come from morocco. Thank you very much for your help I love how this forum is always so alive and full of content and people willing to share their knowledge with the community. Best regards Close look to one tooth:

Mososaur jaw section is it real?
shane545 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Is this mososaur jaw real -
From an estate sale that I acquired some rock boxes. Here are some teeth. The only tag that IDd them was .... wait for it.... teeth! Any ideas? Again, these don't go with my collection but would be nice to ID a little more.

Mosasaurus - lower jaw?
Berkeleybengal posted a topic in Is It Real? How to Recognize Fossil Fabrications
Could experts share the primary indicators to check for regarding authenticity of a Mosasaurus jaw specimen? - specifically root / tooth junctures. I’m aware of the sophistication of fakes in the market. Below is a recent purchase - I’d like feedback on details to look for in verifying authenticity. Thank you! -
I saw a fossil jaw bone segment and teeth when I was in The Calvert Cliff area recently. Another hunter found a very dark colored section of jawbone about 4 or so inches long. It had a good 6-8 teeth in it (same dark color). He was claiming he had found an alligator/crocodile jaw section but it had thorn-sharp teeth. Not what I would have expected to come from a gator or crocodile. I wish now that I took a picture of it but I did not. The only other thing I can remember is that the teeth seemed various sizes, from memory. And were likely all on the side of the mouth where our pre-molars and molars would be. The front of the jaw was missing. I was just wondering what else might leave a jaw section like that. Thanks! Andy

I finally convinced myself to head out to the North Sulphur River again. After 2 attempts of coming up empty handed I was having trouble convincing myself that it was worth the 4 hour round trip excursion. Knowing the date for damming up the river looms nearer and nearer I decided to brave the cold water. I'm glad I did. This time with some help and guidance from a friend my trip was much more eventful. Having NEVER found a Mosasaur vertebrae my trip was made just 10 minutes in when a beautiful Mosasaur vertebrae was just sitting right there on the surface. Already a massive success in my book. A little ways down the creek my friend begins to tell me how he has found 2 Mosasaur premaxes in this spot throughout the year. I replied, "Dude, I would lose my mind if I found a piece of Mosasaur jaw!" No joke, less than 1 minute later we turn a corner and I notice something barely sticking out of the shale and mud at the bottom of the creek. I pick it up, turn it over and staring back at me is a tooth socket! Needless to say, true to my word, I did indeed lose my mind! Apparently my excitement and loud noises I made scared off all the other fossils as I didn't find much else for the next several hours. Still this was by far my best and most exciting fossil hunt. Totally worth getting stuck and sucked up into knee deep mud for.

Hello everyone. Ive got a tough one for you guys. So I have a fossil jaw with a single canine tooth that I’ve had in my collection for a couple years. It was a gift from my boyfriend, so no locality. I tried to have it identified on the fossil forum Facebook group when I first got it, but no one knew what it was for sure. I had a paleontologist post a response and this is what he had to say: ”Hi Marielle Krenzelak, I'm a palaeontologist but I'm not entirely sure what you have there. I'm not concerned with the material that others don't think is bone. It looks to me like the canine tooth (the only tooth you have) is broken. I think the jaw is mammalian based on its overall morphology. I don't think that it is a horse, based on the shape of the symphysis (area where the left and right jaws would have connected) and its position relative to the canine. It is interesting that it has a long post-canine diastema (the smooth area after the canine and before the alveoli, or holes, where the next teeth would have gone). I also think the other suggestions (boar and goat) are also incorrect, again based on the length of the diastema and the shape of the symphysis. Finally, the age constraint someone gave you of less than 20,000 years is not supportable. I've worked on mammals back to ~ 55,000,000 years that have similar preservation. Barring that, I'm just not sure what it is you have there.” So I thought I’d try again on this forum to see if anyone has any idea what it might be? I know we have many experts and actual paleontologists on here. If anyone could help me out, it would be greatly appreciated. Here is a link to the post about it on Facebook in case anyone is in the fossil forum Facebook group and wants to take a look at it: https://www.facebook.com/groups/135008766530423/permalink/1768488489849101?sfns=mo Thank you for any thoughts or insights you have to share!

Hello! I see these edmontosaurus jaws. Edmontosaurus jaw are common? What do you think? Are they good ones or not? Thank you so much. jaw 1

Does this look like a spinosaurus jaw section? The tooth looks legit from what I can see, but the jaw bone looks strange for an apparent Kem Kem fossil. Is that trench along the tooth line, in the top view, a spino feature?

I finished prepping this Enchodus jaw section last year but was undecided about repairing/replacing the tip of the tooth. Comments/suggestions?

Hi Whats jaw is animal it? Location :Tyniec, Southern Poland

Hi just putting this in as a placeholder. Found today at Penarth, South Wales, UK. An ichthyosaur jaw with some other bones. It’s in a shelly limestone which is hard to prep but fingers crossed.

Another trip to the Catskill formation and more fish. This time it was new sites on Rt 6 in Pennsylvania and some of the sites visited before. During the Middle Devonian, the Acadian orogeny had uplifted the edge of the tectonic plate and created a very high mountain range to the east over New England and down the east coast (ref1). These mountains eroded rapidly and much of that sediment was carried west toward the inland sea that covered PA and NY. The Catskill delta shoreline raced westward across the northern part of Pennsylvania in the Middle to Late Devonian. Marine sediments were replaced by near shore fresh water and then flood plain deposits. The Catskill represents this deposition and in this environment the first tetrapods evolved in a very diverse and complex ecosystem. So it's interesting to examine the spatial and temporal relationship of the deposits. Most of the work so far has been done at Red Hill and along Rt 15. So I had read about a Tristichopterid jaw that was found in the road cut along Rt 6 at Wyalusing Rocks and wanted to take a look. That site was a little disappointing but another road cut east of there in Laceyville, PA produced this interesting and almost complete but poorly preserved jaw. And after some reconstruction. The plates above the jaw appear to be some kind of head plates but because of the poor preservation I have yet to see any ornament. There are teeth in there and I will attempt to expose them when I get to my new house in Connecticut. and the counter-part More to come

Hi all, First time using the forum. I got this from a local rock and mineral show years back, but they gave me no information other than that it was a “prehistoric deer.” Using this, I did some research, and highly suspect that it could be the jaw of a Leptomeryx species (which would put it somewhere in N. America?). It definitely resembles the pictures I’ve seen. Any and all help would be greatly appreciated.
