Haven't had time to post here lately, but I carved out a slot so here we go. In April of last year (2019), I had a chance to visit China. When I was in Beijing, one of my goals was to see the feathered dinos. I visited two museums that had them. One was the Geological Museum of China. The other (The Beijing Museum of Natural History) will be the subject of another post. I took hundreds of pictures there, but I can't post them all here. I have selected some of the better ones, focusing on the feathered critters. You'll have to excuse the lighting and quality of some of them. The light was low in parts of the museum and I had to shoot through glass most of the time. An Iphone was my camera and I've had to shrink them to fit on here. It was a great museum and they had so much to see besides the fossils. This greets you when you walk in along with some other fossils and minerals. The verts are from a Shantungosaurus giganteus Hu, (a hadrosaurid) found in Shandong Province in 1973.The other guy is a Lufengosaurus magnus (Young). Don't know the rest of the details other than 1957 year. Representing The Fossil Forum with my t-shirt. First up is Caudipteryx zoui Ji et al, Early Cretaceous, Beipiao, Liaoning Province. Next is Enantionithes gen et sp indet, Early Cretaceous, Lingyuan, Liaoning. Liaoxiornis delicatus Hou et Chen, Early Cretaceous, Lingyuan, Liaoning. Next are several specimens of Confusiosornis sanctus Hou et al, Early Cretaceous, Beipiao, Liaoning. The darker shaded area is the shadow of my phone, sorry. continued....

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?

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."

Hello all I received this insect in a trade with another forum member a couple of months ago. All other insects I could ID, but I can't find this one. It is from the Yixian Fm. of Liaoning, China. This formation is early Cretaceous. I finally got a new camera. The pictures are not perfect but I hope they do the job. Insect is a little over 1 cm. Greetings
