This Keichousaurus is interesting in that it got a lot of grainy deposits. Is it due to a decaying body of the Keichousaurus or they are fossilized deposits of organic matter over the body of the Keichousaurus?

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?

Are these two marine reptiles Xinpusaurus? It is from Guanling, Guizhou of the Triassic formation. By the way, there seems to be some vertebral bones inside the body of the bigger one, any idea what is that?

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?

Chinese Dinosaur Skeletons in Burrow Buried by Volcanic Eruption
DPS Ammonite posted a topic in Fossil News
Two skeletons of the newly described Early Cretaceous ornithopod dinosaur Changmiania liaoningensis were found in a burrow that was buried by a volcanic eruption about 150 million years ago in China. There is a great photo from the Peerj article of gastroliths found clustered inside the skeleton. We should show this photo to all members that show us purported gastroliths as an example of the level of proof need to prove that their stone is a gastrolith.

I am a fossil collector in Hong Kong and I keep seeing lycoptera for sale everywhere in local fossil shops. However,fossils like lycoptera are from China and it is difficult to prove its export date,if not impossible.Yet I know for a fact that it isnt illegal to keep them here and some fossil collectors even bring rarer Chinese fossils on TV shows and mall exhibitions locally(psittacosaurus and dino eggs).Thats why Im conflicted between shall I acquire one or not and want to hear your opinions on this

This fossil was from Yunnan, China. Of Triassic formation, same layer as Keichousaurus. It’s 55cm in length. Any idea what it is?

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. Some fossil amphibian skulls, can't remember where from or what species exact, some of them were still in a matrix, the bones were almost red and looked a bit similar to that of Eryops. He also sold small plastic containers of tooth fragments from China/Mongolia, labelled "Tarbosaurus". I bought one of these containers. The seller told me they were collected near the border between China and Mongolia. I was never truly sure if they were 100% Tarbosaurus, could literally be any other theropod. And considering there was no specific location or formation, it's really hard to tell what I've actually bought. I've had some people write to me, wanting to buy the fragments, and have each and every time told them, that I really can't know for sure what these fragments belonged to. Just recently I bumped into this tooth (as seen below here) online for sale: It is described as a Carcharodontosaurus indet. tooth from the Kem Kem beds of Morocco. And the coloration looked oddly similar to one of the fragments I bought at the fossil show. Now, before you say anything, I know that coloration varies a lot within every location, and some locations may yield fossils that look identical in coloration to other locations' fossils, but I just thought the reddish tone underneath the enamel seemed very familiar in regards to especially 1 of the fragments, which is a partial tooth, and also the most complete one from the little container I bought. (See the partial tooth below): The tooth on the above pictures has the following serration counts: Mesial carinae: ~18 serrations per cm, roughly 2 per mm. Distal carinae: ~20 serrations per cm, roughly 2 per mm. It measures: 2,5 cm at its longest dimension. 1,4 cm wide. About 0,9 cm thick at the thickest point. After seeing the picture of the Carcharodontosaurus indet. tooth for sale, I thought maybe this could be a Kem Kem tooth too. Anyone who's got a guess or a hunch?

Hello fellow enthusiasts. I just came across two items from a friend who’s parents came to Europe from China in the 80s. Apparently they gave away a bunch more as random gifts to friends and colleagues :). The first one seems to be dentures of some sort and the other one a vertebrae but I have no clue from which species. Do you have any ideas what these might be?

Keichousaurus - real, fake, altered?
Wrangellian posted a topic in Is It Real? How to Recognize Fossil Fabrications
Came across this one and wondered if it was fake or doctored. I have my suspicions - for one, the legs look disproportionate, but I wouldn't know. I wouldn't mind having one of these if it's real and the price is right. This is the only pic available... maybe not big enough to tell anything for sure? but I know some of you have a pretty good eye!- 10 replies

Hi everyone, I just received this tooth, it is clearly an upper carnassial of a carnivore, it should come from Gansu, China. Can anyone help me with the identification? Based on it's appearance and what the seller said to me I think it's from the huge mustelid Eomellivora

Concave convex Keichousaur
FF7_Yuffie posted a topic in Is It Real? How to Recognize Fossil Fabrications
I know these are often suspect, but this being both concave and convrx seems hopeful. Bit of a botch on neck and head, since that is on the other side. On most I see for sale, the bones are usyally darker. Is that down to a poor prep or are tge darker ones often colored/highlighted. Thanks. Getting a Keich never appealed to me, but if price stays low...- 6 replies

My Birthday is coming up in a few days and I am looking to knock something off of my bucket list. This insect has caught my eye. It is within my budget and from a reputable seller, but unfortunately, I know little about fossilized insects, and less about ones from China. I have done some research and it seems that Dragonflies (and many other insects) are common in the given formation. From what I can tell, there is nothing suspicious about this one, but I thought I would poll the audience just in case. Dragonfly Larvae (Roughly 2in or 5cm long) Yixian Formation (Cretaceous) Huangbangi Valley from Liaoning Province of China

Jinyupelta is the oldest confirmed ankylosaurid with a tail club, and I'm speculating that ankylosaurids evolved tail clubs to counter the emerging threat of giant theropods like carcharodontosaurs and tyrannosaurs. Since the Albian-Turonian of China boasts a number of giant carcharodontosaurs (Chilantaisaurus, Shaochilong), is it possible that Jinyunpelta could effectively take down a Chilantaisaurus/Shaochilong-type carcharodontosaur or Suskityrannus-type tyrannosaur with its tail club?
