Real or fake mosasaur jaw
ruminate posted a topic in Is It Real? How to Recognize Fossil Fabrications
-
I recently saw a 1.2cm long Oligocene mammal jaw from South Dakota, judging by the coloration of the specimen from the Brule Formation, up for sale. The jaw is referred to as Leptictis haydeni, but the description states it to be from a primitive weasel. Moreover, I have never seen any Leptictis material for sale and the dentition looks as much like that of the relatively similarly named but much more common Leptomeryx than any leptictid. Thanks in advance for any guidance Othniel

Hi, what species of mosasaur is this? From the phosphates of Morocco. I will tag you @Praefectus @pachy-pleuro-whatnot-odon. I am thinking Eremiasaurus left dentary with some stuff?

The fossil in the images below is being sold as that of a Merycoidodon, but it looks rather small for such an animal, so I wondered if it could be from a smaller Merycoidodontid or perhaps another small ungulate like Leptomeryx. Thanks in advance for any guidance Othniel

12.6" Mosasaur Prognathodon Fossil, 2 lbs 6 ounces, 4.7 inches wide, 1.5 inches thick Location- Qued Zem, Morocco Seller doesn’t mention anything about repair or restoration so I’m not sure about that I’m wondering if it’s restored. Are the teeth original to the jaw? And are those bite marks

Greetings, Two days ago I found this jawbone while I was walking through the countryside, and I've doubts if it belongs to a Wolf, a Coyote or a dog, although I think it's belongs to a Coyote. Thanks you for help!

Hunting 10 days ago, I found a fossils at different spot and now have the time to show these: I believe it to be a Tapir right side mandible with no teeth. As time permits , I may try to ID which tapir. Upper right is an antler stub, then a barnacle cluster and a number of shells that I have not IDed. I think the coral on the right is Solenastrea hyades, which did exist in the Pliocene_Pleistocene of Florida But the fossil I want to identify is this: What is it ?... echinoid ? I have a sand dollar that is something like that... maybe gastropod worn down to an inner slice ? In this case, your guess is definitely as good as mine, because mine is not very good.

I am once again asking for your expertise! This is one of the nicest fossils I’ve found, considering fish jaws and teeth are not that rare - but finding a jaw with teeth inside doesn’t happen that often at this beach. It was found at the Zandmotor beach in the Netherlands. This beach is known for Pleistocene mammal fossils. Fish vertebrae and teeth are also common, which may be way older than Pleistocene. I posted this fossil on Reddit some time ago too, but wasn’t able to get a conclusive answer. Someone suggested it might be amiid, but I don’t think amiid are found here. Could it be esox lucius (pike)? The total length is just short of 4cm. Unfortunately I had to apply paraloid before desalination, because the fossil was already starting to fall apart.

Hello, A family friend passed away and left me his rock, mineral, and fossil collection. Much of it was labeled, but there were several boxes of odds and ends that I’ve been working to identify. I believe this is fossilized bone as it’s heavy for its size. Forgive me if this is just bone. I don’t know where this is from, but my friend collected in CA primarily in the 70s through 80s. Most of his stuff was from local shows around that time. Any ideas of what this might be?

From the album: Middle eocene fossils from Qatar
Now with teeth Midra shale formation Qatar, Middle eocene age around 5mm in length -
This is being sold as a Spinosaurus premaxillary jaw from the Kem Kem, but I'm suspicious. Any opinions? And if not Spinosaurus, what could it be? Size 23 cm / 9.06 inch

Hi all, This jaw was just listed on a particular auction site and caught my eye. Locality according to the seller is Hell Creek formation, Montana. The fossil is 15mm long. Their ID is just "dinosaur" of unknown species. To my amateur eyes, the size and "shelf" on the inside of the bone makes me think lizard, but the teeth really look like those of dromaeosaurs. Any thoughts on ID? Lizard, juvenile dromaeosaur, or bird even?

From the album: Middle eocene fossils from Qatar
Some kind of crusher fish jaw, presumably Pycnodont, collected from midra shale formation in Qatar, Middle eocene aged. Around 6mm in size. One tooth can be seen still embedded into the jaw. Might be the first specimen of this kind ever found here-

Hello, saw this for sale and was wondering whether it was croc or spinosaurid, it’s from Morocco, Africa. I’m leaning towards spinosaurid, but I’m not an expert. Please also let me know if there is any repairs/restro. Thanks a lot!

Hi Guys, On our hunt today for shark teeth my daughter found this jaw bone. It feels fossilized. Found in eastern NC in a stream that cuts through a lot of different ages including Pleistocene deposits. What do you guys think? Thanks, John

Hi I recently bought a pallet of white river fm fossils and this can with it. The box said mammal fossils and at first I thought maybe hell creek but I don’t have any information on where it’s from. Much appreciated! -Daniel.B

Unidentified Early Creataceous (Wealden) archosaur jaw bone with tooth
pachy-pleuro-whatnot-odon posted a topic in Fossil ID
I recently purchased an odd little archosaur jaw from the Wealden at Bexhill-on-Sea in East Sussex, UK. It's 14.88mm in length and 4.03mm tall, with a single remaining tooth of approximately 1mm in height. The seller told me he thought it would be Aigialosaurus, something I thought odd due to that genus only being known from Hvar in Croatia, and being much younger (Cenomanian) than this specimen (Valanginian). However, it turns out that a jaw was found at this locality at some point that has since been moved to the Bexhill Museum and was identified as Aigialosaurus (though, based on what, I don't know): While I'm working on figuring out whether the jaw in the other thread can indeed by attributed to an early mosasauroid (Aigialosaurus?), I wanted to ask people in this thread what they make of my particular section of jaw. Ventral Terminus (end of jaw) 1 Terminus (end of jaw) 2 Observe the tooth attachment with raised sockets, not unlike in mosasauroids. Details of tooth attachment. Here are the photograph of the jaw from Bexhill that was identified as Aigialosaurus again, for ease of reference (source): So, what do you guys think? Reptile or fish? Crocodile, lizard? Do you think my jaw compares well to the one identified as British Aigialosaurus? @caterpillar @Praefectus @ThePhysicist- 4 replies

Hi all, I was recently told about supposed Aigialosaurus/aigialosaurid (mosasaurus) material from the Wealden at Bexhill-on-Sea in East Sussex, and was wondering whether anybody knows anything more about this. Because, as far as I'm aware (Wikipedia), Aigialosaurus is described from Hvar in Croatia and, moreover, temporarily restricted to the Cenomanian, whereas these remains, stemming from the Wealden, would be Early Cretaceous in age (Berriasian through Aptian) - most likely Valanginian, as they were recovered from Bexhill-on-Sea. (Image source) I must say these remains do look rather mosasauroid, although I've been unsuccessful in finding further information on the specimen, which is supposed to be housed in the Bexhill Museum. The person who first told me about them remembers having seen a newspaper article, believes the British Natural History Museum was involved with the specimen back then, and had heard about a paper being written about it. That's about all I have to go on for now. So my questions right now are: does anyone have more information on this specimen; know of the publication; and what do people here generally make of this piece: is it mosasauroid, or could it be something else? @paulgdls @DE&i @Praefectus @caterpillar @The Amateur Paleontologist @Kosmoceras @ThePhysicist @Welsh Wizard @DanJeavs
