I need help identifying these sauropod teeth from Yixian Formation
-Andy- posted a topic in Fossil ID
Hi all, I have several sauropod teeth from the Yixian Formation of Liaoning that I need help identifying. This is Tooth 1 - White Length: 44 mm Formation: Jianshangou Beds of Yixian Formation Locality: Chaomidianzi, Sihetun, Beipiao, Liaoning Province I believe this is a Dongbeititan dongi tooth as this tooth has the morphology of titanosauriform teeth, and Dongbeititan is the only titanosauriform from that locality as far as I know. The formation is based off the locality of Chaomidianzi (my source was confident of that locality) --- This is Tooth 2 - Red Formation: Lujiatun Bed of Yixian Formation Locality: Yanzigou, Shangyuan, Beipiao, Liaoning I believe this is a cf. Euhelops sp. tooth as this tooth has the morphology of titanosauriform teeth, and cf. Euhelops sp. is the only titanosauriform from that locality as far as I know. The formation is based off the locality of Yanzigou and the red matrix. I've compared this matrix to multiple Yanzigou locality fossils of the Lujiatun Beds and they are identical My ID is based off this paper "Basal titanosauriform (Dinosauria, Sauropoda) teeth from the Lower Cretaceous Yixian Formation of Liaoning Province, China" --- This is Tooth 3 - Partial Formation: Lujiatun Bed of Yixian Formation Locality: Yanzigou, Shangyuan, Beipiao, Liaoning I believe this is a cf. Euhelops sp. tooth as this tooth has the morphology of titanosauriform teeth, and cf. Euhelops sp. is the only titanosauriform from that locality as far as I know. The formation and locality is based off the red matrix in the cross section. This tooth was resold from my source but he confirms it's definitely within Beipiao and either from Yanzigou or Sihetun. I've compared this matrix to multiple Yanzigou locality fossils of the Lujiatun Beds and they are identical --- This is Tooth 4 - Tiny Formation: Yixian Formation Locality: Sihetun, Beipiao, Liaoning This is the toughest tooth of all due to its size and incompleteness. It's the top half of a spoon-shaped crown. Again, the source admits being a reseller but he promises the locality is accurate. I believe this is a Titanosauriform indet. I showed this tooth to @hxmendoza and he agrees it's a tooth, not a claw. The closest match I can find to this tooth is MSNM V6214 from "Sauropod teeth from the Middle Jurassic of Madagascar, and the oldest record of Titanosauriformes" May I have your thoughts on these IDs please? Thank you.

Caudipteryx from Liaoning, China
Crazyhen posted a topic in Is It Real? How to Recognize Fossil Fabrications
The specimen below is said to be a Caudipteryx, not sure if it's a C. zoui or C. dongi. Is it a genuine one? Or a very good replica?

This is said to be Jeholosaurus limb from Liaoning of Early Cretaceous Formation. Is it genuine? It seems the limb is incomplete with missing claws?

Hi everyone, I am currently thinking about buying this Psittacosaurus femur, as it would be a nice and a bit of a rarer addition to my dinosaur collection. The piece is said to have been found in the Yixian Formation, Liaoning Province, China and it measures 14,5 cm And while it looks like a genuine and okay bone to me (with perhaps some composite elements like the little protruding part which is typical of Psittacosaurs) I am not really an expert on Chinese dinosaur fossils. The bone looks like the femur on the replica skeleton I own, but I am not 100 % sure whether this is actually the real deal or not. And if it is real, if it does belong to Psittacosaur or just another animal? @Troodon & @LordTrilobite what are your opinions on the bone?

Is this specimen an Ikechosaurus? It is from Liaoning, China. And there seems to be two skulls at the anterior part, possibly a dislocated lower jaw and skull?
-
Hi, this skull is from Liaoning, China in Yixian, early Cretaceous. Any idea what it is? Whether it is reptilian or mammalian species?
-
This tooth is from Beipiu, Liaoning. Any idea which dinosaur is it? And how about its condition?

I saw this Psittacosaurus fossil on the Internet fossil owner says this fossil buy from Liaoning Something seems really odd about it is this fossil real? I would truly appreciate any response to my question

This clutch is said to be found in Beipiu of Liaoning, China. It is said to be the primitive mammal of Triconodontidae. You can see the presence of individuals of different sizes. Any idea which species is that?

Turtles from China...again
sneakyelf posted a topic in Is It Real? How to Recognize Fossil Fabrications
Manchurochelys liaoxiensis from Liaoning province. These turtles have shown up in the forum before, some with the conclusion they are real, some not. Here is an incredible display of turtles with fish! However, I am highly skeptical despite coming from a reputable source. They seem to have a halo of color all the way around them. On extreme angles there are some parts where the shell is not attached to the matrix. Even the fish are "on" the matrix, not in it. It is not resin, as I have exposed many parts to a soldering iron. The crack on that back seems to run under, not through, the turtles but is visible on the front where the turtles are not. It even runs under, not through, a limb. To me, a best case scenario is that these "real" fossils were placed onto a stone slab, but that seems like a lot of unnecessary work. If the turtles are casts that are put onto the matrix, is there an easy way to tell? Would x-ray be useful as the turtle and the matrix are likely different densities if the turtles were added on? And can anyone recognize the fish? If they are millions of years apart, that might answer the question. but where are the heads of the fish? Llastly, for a fascinating read on fakes, check this out: https://www.researchgate.net/publication/265208436_Fossil_fakes_and_their_recognition This is not the site of a seller, so it should not break the rules of this forum...if I am not mistaken. Thanks for your thoughts!

This small specimen was said to be a naturally polished petrified wood found in a river at Liaoning, China. I cannot find any tree rings or wood features. The surface does however has some irregular patterns. Do you think this is simply a geological specimen or a fossil? It measures 6x4x3cm.

Please could you let me have your view on the authenticity of this small Psittacosaurus skull? It is from Liaoning of China.

The order of Acipenseriformes (Sturgeon-like fishes) both includes sturgeons (Acipenseridae) and paddlefish (Polyodontidae). At least three Sturgeon-like fishes (Acipenseriformes) can be found in the Jiufotang Formation (Jehol Group) and in the Yixian Formation in western Liaoning and northern Hebei Province China: Peipiaosteus pani Liu and Zhou, 1965, Protopsephurus liui Lu, 1994 and Yanosteus longidorsalis Jin, Tian, Yang & Deng, 1995. The Jiufotang Formation - where Peipiaosteus comes from - is dated to about 120.3+/-0.7 million years ago, which was during the Aptian age of the Cretaceous; the Yixian Formation - where Protopsephurus liui and this Y. longidorsalis can be found - is dated slightly older, around 125-121 million years ago (Barremian-early Aptian). Diagnosis from Hilton et al 2021, p. 2: "A †peipiaosteid (sensu Grande and Bemis, 1996) that differs from all other members of the family by possessing an extremely elongate dorsal fin. Other characters that, in combination, differentially diagnose †Yanosteus from other Acipenseriformes include short, stout pectoral fin spine, supraorbital sensory canal anterior to frontal surrounded by a series of small bony tubes, and the absence of epaxial caudal-fin rays."

Any view on the authenticity of this bird fossil? And the species? It is from Xixian Formation of Liaoning.
