Velociraptor? Looks Kem Kem to me - plus one with unusual preservation
FF7_Yuffie posted a topic in Fossil ID
Two teeth from Djadochta. First one screams Kem Kem to me. 1st tooth is 1.5cm. I can't figure out how to get in touch with the seller on the website it is sold from to get more specifics. I'm sure there is a way, but I am missing it. Second tooth is 2.cm - Unfortunately, the only picture I have of it at the moment, although supplier is trying to get more from the person selling it. It will likely sell before he does get one, so I figured I'd post what I have now. This one, the preservation is unusual--I thought Djadochta teeth were a very light shade? Has anyone encount -
Hi picked this up at a mineral show over weekend here in Taiwan. It was sold as tooth from Djadochta, if anyone can take a look? Hope photos are ok. It is small, 4mm. So its tricky to get a pic, also hindered by my essential tremor.

I purchased these as Ingenia yanshini which I think became Ajancingenia, which then became and is currently Heyuannia. The formation provided is the Djadochta Formation, but that doesn't seem right since Ingenia/Heyuannia is not found there as far as I've checked. Unfortunately, there isn't provenance other than Mongolia attached to them to say whether they come from the Barun Goyot Formation where Heyuannia yanshini is found. While I'm not necessarily doubting the original ID, I just don't really know. I'm not expecting a positive or diagnostic ID to the genus level, but I wanted

Mongolian carnivore tooth with jaw fragment. Is this a croc or theorpod?
-Andy- posted a topic in Fossil ID
Hi all, I had posted about this tooth years ago and the conclusion back then was that its preservation was too poor for any proper ID. I am hoping that with new information we can at least determine if this is a crocodile or theropod. I discovered today that this tooth preserved some serrations First up, this tooth was acquired from a source with many Mongolian material. He called this an Alioramus tooth but I am not comfortable calling it that yet Secondly, a museum curator (who has handled Mongolian material) examined this tooth in person. He concluded this tooth was- 11 replies

A new small dromaeosaurid dinosaur, Shri devi, from the Late Cretaceous deposit of the Barun Goyot Formation at Khulsan, Mongolia, is described here. Pretty cool unfortunately no skull but teeth should be small and very similar to Velociraptor Paper provides a good reference source to ID dromaeosaurid bones from other regions http://digitallibrary.amnh.org/handle/2246/7251 Check out that Digit II killing claw

Is it possible that these are Psittacosaurus vertebrae? The seller gives poor locality with only saying it’s from Mongolia and they are around 1.5 cm for the largest one. Thank you! @Troodon @LordTrilobite

Mongolian Placoderm Fossil Might Change Our Ideas About Shark Evolution
Scylla posted a topic in Fossil News
We thought sharks' cartilaginous skeletons existed because endochondral bone evolved after sharks branched off the family tree, but this Placoderm common ancestor of sharks and bony fishes has bone. This indicates that sharks may have lost the ability to make endochondral bone. https://phys.org/news/2020-09-ancient-bony-fish-rethink-sharks.html-

So I bought these tooth-fragments at a fossil show back in December in Hamburg, Germany. The seller had a lot of different fossils, including a huge ilium bone of a sauropod from the Kem Kem beds, as well as a tibia from a large indet. theropod (Which according to the seller was Spinosaurus). Other than that, he sold large tooth fragments from the Montana, Hell Creek formation, probably Rex, but no complete Rex teeth. Some dromaeosaurid teeth from the Hell Creek formation, and various herbivorous dinosaur teeth from the same formation too. A lot of ichthyosaur bones from Dotternhausen, Germany

Neenan DOI: 10.1111/joa.13253 " In life, the endosseous cochlear duct of V. mongoliensis wouldhave housed the basilar papilla—the auditory organ of tetrapods(Gleich et al., 2005; Walsh et al., 2009). As the length of the cochlear duct has been interpreted as a rough measurement of the basilar papilla, the length of the duct can be used as an estimator of hearing frequencies in non-avian dinosaurs (Witmer and Rid

I acquired this dinosaur bone several years ago. It is said to come from Mongolia. Unfortunately, the seller didn't know what dinosaur and what type of bone it was. I definitely know for sure that it's real. The bone was checked by an expert. The bone is 38 cm long, between 15 and 20 cm wide and between 5 and 15 cm high. Maybe someone has an idea. Thank you in advance!

Hi everyone, I'm a complete novice here, I purchased this strange rock as a souvenir when travelling through Mongolia and Russia if was bought from Nomads who forage the area close to lake Baikal on the Mongolia side of the border. It strangely drew me to it as it was sort of hidden under some other prettier looking rocks. The internet doesn't seem to say it's likely to be a mushroom, although as I'm sure you will agree from the photos it's easy to believe it is. I'd appreciate anyone expertise and thoughts anyone might have on Mushrooms or anything similar they have s
