https://phys.org/news/2018-11-oldest-known-ancestor-modern-primates-north.html Tiny jaw fossil with big implications for our evolutionary history
-
Found this jaw and I am wondering if it is modern or ice age. I did the match test and there is no smell what so ever. Found in the Arkansas river in kansas.

These pics aren't the best. I forgot to put a scale object in the photo. I hurriedly decided to shoot these because the setting sun was providing some good lighting. This piece is small, about 1.5 inches in overall length. There is an alligator scute in the background for rough approx. size comparison. I am not sure if this is fossilized, but the teeth look familiar to me. Is this a juvenile of something larger? Thanks! (Peace River, Florida, Bone Valley formation, Polk county, Hawthorn group)

My husband and I found some really great fossils in Onion Creek just east of Austin, TX today. Many of the usual gastropods but also some mammalian bones including a jaw with teeth intact. Welcoming any help with IDs here. Let me know what angle or side would be helpful if I failed to get the shots necessary to narrow it down. Many thanks!

Different Mosasaur Jaws / Skull
Abstraktum posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello everybody So, these are some jaws / skull all from Mosasaur / Kem Kem that run on actions right now. It's out of my price range, but I post this here for educational purposes. I want to point out: The first Jaw is a composit. The seller admits it in the description. Real teeth, real jaw fragments, but put together. I have to be honest: I would be fooled by the first one. Can you point out why you see that the first Jaw is a composit? For me it looks like there are just some crack repairing. According to the seeler, the skull has been reinforced with a metal frame and camouflaged afterwards, some minor traces of preparation might still be visible. The rest is untouched acording to the seller. I can't provide more or better pictures. Thank you very much for your help! Jaw #1(composit) Jaw #2 Jaw #3 Skull -
Edmontosaurus jaw section
kirkjeremiah23 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Thoughts on this jaw section of a Edmontosaurus. Has there been any restoration? Authentic? These are the only pictures sent to me. He is asking a pretty penny debating on if it would be a good addition for my collection. Any information is greatly appreciated. Thanks again guys -
Yet another mosasaur help thread
Captcrunch227 posted a topic in Is It Real? How to Recognize Fossil Fabrications
I picked this up before even knowing that people could or would fake mosasaur jaws. I've done the best I could could but this rookie could still use the help. This mosasaur piece is from Morocco and that's all I've got. Thanks everyone -
Just got back from the Orlando Fossil Fair 2018, I bought some nice fossils but many were not identified and I want to confirm ID's for ones that were. There's a lot of fossils so I'll label each one with information and my own opinon on them. All the fossils shown are allegedly carnivores and found in the Suwannee River in Florida (excluding two of them). The furthest on the left will be #1, and the furthest on the right will be #4. I'm not convinced that 1 is a carnivore but besides that I don't have any hypothesis on what the others could be. The left one in this picture is 5, the one on the right is 6. Five reminds me of a bear, and I don't have any idea what 6 is or if it's even a carnivore. The tooth will be 7 the jaw will be 8, both are allegedly dire wolves (they're not associated) from 'Northern Florida', I don't have an exact locality unfortunately. I suspect these both belong to dire wolves. The furthest left will be 9, and the furthest right is 11. I suspect 9 and 10 to be racoon teeth, but I'm not sure if racoons are found in the Suwannee river. At first I thought 11 was a canid, but after looking at it for awhile it looks more like a feline. This last specimen will be 12, right now I'm stuck between a primitive canid (possibly leptocyon) a feline, or some sort of fox. This specimen was also found in the Suwannee, like the rest except the dire wolves. If you need more pictures I can take some and post them within the hour. Thanks in advance!

Hello all would this be a spino jaw section or a croc jaw section ? And the tooth has been put on the jaw.

I obtained this mammal jaw at the Colorado School of Mines Geology Garage Sale a couple of years ago in a box of rocks that had been detached from their labels and so lost much of their scientific value. That made the box of rocks cheap, but it means that I am on my own to figure out what all of it is and have no location information at all. I am hoping that someone on here will maybe recognize it enough to steer me in the right direction for even a higher taxonomic level identification. I am more than happy to provide photographs from any additional angles that would be helpful so please just ask! Any thoughts are greatly appreciated!

Recently I posted this fossil in the fossil preparations forum in order to get some assistance in cleaning the fossil. The bone comes from the Kem Kem Beds, so the sandy matrix was fairly easy to pick off with a pin vice and a DRY toothbrush I believe this is Carcharodontosaur because of the amount of space between tooth sockets and the presence of labial foramina (both of these features outlined in photographs) but I'm not 100% sure. The size of the fossil is 6x3x1 inches. I've been driving myself nuts trying to figure out what this thing is, so I've decided to post it here because I'm all out of ideas

Hi, wanted to ask for opinions about the identification of this partial jaw, offered to me as a Spinosaurus jaw (or Spinosaurid), but unsure on how to tell the difference between a spinosaurid jaw and a crocodilian jaw. Thanks.

I bought this at a garage sale in Tucson the other day. They told me they think they bought it at a museum gift shop.

Mosasaur fabrication?
bcfossilcollector posted a topic in Is It Real? How to Recognize Fossil Fabrications
Looks like a complete fabrication, barring the crowns? @Tidgy's Dad @-Andy- @Troodon -
Could this be a plesiosaur(elasmosaurus) jaw? I tried comparing but it's hard to see the picture of jaws in ideal positions and angles and such. Also, with so many extreme teeth it can be hard to see perfectly in a lot of pictures. (Location-wise and all, it could be, this is just about the physical jaw itself)

From the album Sharks and fish
The shark relative is genus of eugenodontia holocephalid from the Carboniferous-Pennsylvanian age Anna shale formation, Carbondale group, found in different Illinois coal mines. I dont know(yet)which mine these were found in. This unidentified species is of the "vorax-serratus- crenulatus-heinrichi" or "E. heinrichi group", with the teeth being more of a standard triangular shape, as opposed to being thinner and pointed at a forward angle as in the "E. minor" group http://www.thefossilforum.com/applications/core/interface/file/attachment.php?id=501751 -
From the album Marine reptiles and mammals
2 unidentified mosasaur species' anterior end of premaxillary bones. One with teeth broken off just beyond the skull, and the other has 2 remaining teeth, with the rest broken off at the level of the skull. the larger fossil was found in the phosphate mines of Khouribga, Morocco. ive since lost the information for the smaller fossil, sadly. -
From the album Sharks and fish
Front side of armor which I believe could be the edge of the jaws! It comes to what would have been the razor sharp shearing edge, greatly worn down now, though. I also believe it could be the jaw because of the clear vertical wear lines on the surface, from being sheared against the inner surface of the other jaw, which is how they kept the edges razor sharp like scissors. I have seen similar wear lines on placoderm shearing jaws, so what I believe to be reasonable observations point to the possibility(maybe even likely?)of being from the cutting edge of the jaws. -
Hello, A recent find of ours. I've been told by someone knowledgeable in this area that it's a Disarticulated lower Ichthyosaur jaw ( the long bones on the back) It's been scavenged after death so everything is scattered. On the otherside are other bones, shells and what look to be 5 teeth. Other Side with Teeth Close up of what look to be teeth, I've circled them in red.

Please help me identify this fossil found yesterday on a hike Door County. It was found among very common fossils like corals.
