Hello, I just joined this forum. Back in the early 2000s I bought a few dino eggs, they came from China. Since then, as I understand, China has cracked down on export of fossils/eggs, it's illegal to export them. Eggs are now more expensive and harder do get. Of course there are a lot of fakes on online so one needs to be careful. I read prior posts here about eggs with pics of fakes and genuine ones. Below are two Hadrosaur eggs I saw online, and wanted opinions if they are genuine or not. They look legit to me but I'm no expert. I assume it's not illegal to sell/buy these eggs within the USA, at least the ones already here.

It’s from Hubei, China and no age is given other than Ordovician. Apologies for the blurry images, it’s been shipped to somewhere else for a bit.

Real and bad preserved, or carved and paint Keichousaurus ?
Brevicolis posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, i saw this Keichousaurus from Gouizhou, China, on auction today and think theres something wrong about it. The bones look like If they're carved from one piece, the toes look paint. But im not sure If its a complete fake. Because many of the structures seem to be real, but badly preserved. Also, i dont know how common it was in the 1980/90's to fake Keichous. Thats when it was found. So what do you think about it, is it a real and bad preserved one, a 50/50, or a complete fake ? Thanks for any advise ! (The seller didnt made that many close up pictures from different angles, sadly)

Yangchuanosaurus Theropod Tooth From Shaximiao Formation, Zigong, Sichuan Province, China?
Pliosaur posted a topic in Fossil ID
Hello, I would like to know if this tooth may possibly be from Yangchuanosaurus species. It is from the Shaximiao Formation, Zigong, Sichuan Province, China Formation is Jurassic age and relatively very little material is known from this formation and particularly in China although seems like Yangchuanosaurus has been described from this location et al. (1978) named Yangchuanosaurus shangyouensis on the basis of CV 00215, a complete skull and skeleton which was collected from the Shangshaximiao Formation, near Yongchuan, Yongchuan District, Sichuan. Tooth measures less than 2 inches and the serrations appears too worn to make an ideal identification, although looking at teeth from skulls of Yangchuanosaurus, they do seem very similar , in shape and size Any help would be appreciated! Thanks!

Hi everyone! I saw these for sale listed as "Sabretooth cat upper molars from the gansu province of china", which is really cool since I've always wanted sabre cat material but I have no experience with these fossils (since they are unreasonably difficult to find/ get a hold of) so I'm hoping the forum can give a second opinion on the ID and point out any potential funny business (besides the obvious repaired break on one, which I'm okay with). Size isn't listed, but I have contacted the seller asking about that and am awaiting a response. Any insight is appreciated as always!

There's tons of images of all kind of Keichousaurus specimens online, but I couldn't find a single image/video of where do they find them or how are they extracted. Does anybody know where this kind of material can be found? Disclaimer: It is common knowledge that most (?) Keichousaurus are found in China, the question doesn't go in that direction.

Howdy! I read over the thread on dinosaur eggs and I'm still not sure if these are real. These two eggs supposedly come from the nanxiong formation of ganzhou China. They are being sold from South Korea.The texture of the egg shell looks like it could be Oviraptor. Is it suspicious that both eggs are listed as being the same size 18 x13 cm? Thanks.

Keicho - no shoulder blades, no pelvis...?
Ezio Bonsignore posted a topic in Is It Real? How to Recognize Fossil Fabrications
No shoulder blades or pelvis are visible. Just a matter of presentation/preparation, or someone sort of forgot such annoying details while carving/painting a fake?

I'm pretty certain that this is a cambrian Harpetid, but am not entirely sure. It's listed as a Palaeoharpes primigenius from the Sandu Formation.

I recently acquired three tooth fossils from southwestern China initially labeled as a "Plesiosaurus indet." tooth. The specific locality of the tooth fossils is the Lower Shaximiao Formation, Zigong, Sichuan, China. The age of the Lower Shaximiao formation ranges from Early to Middle Jurassic. The only known plesiosaur species from the Shaximiao formation is Bishanopliosaurus zigongensis, a rhomaleosaurus. If these three tooth are indeed identified as a plesiosaur tooth, they probably belong to Bishanopliosaurus sp. Can anyone help me to identify whether these teeth are plesiosaur teeth?

Hello! I asked this question in the Facebook group so I apologize if any of you are seeing it for a second time, but it was buried in a comment chain so I’m hoping to get a few more expert eyes on it. I received this beautifully prepared Keichousaurus today and it’s truly awesome to see it in person, but now that I’m able to inspect it more closely I’m thinking it may be a composite. There are a few things making me lean that direction: 1) There is an obvious mismatch in the patterns on the matrix, both front and back, when comparing the chunk that the body is on to the chunk that the skull is on. For example, the partial fish fossil on the righthand side just abruptly stops at the seam (last photo, blue arrow) … but it’s maybe possible that this is due to variable flaking/weathering and reattachment 2) The head is dorsal while the body is ventral … but I know it’s possible for this to happen naturally if the neck is twisted 3) The white “veins” that appear to run across both plates (skull and body) are, I think, true calcite veins in one plate and scratches intentionally placed to match on the other. For example, the red arrow in the last photo points to a junction where a true calcite vein from the body plate should cross the skull, but no vein is visible in the skull. A “vein” reappears above the skull but I believe this is just a surface scratch. On the other hand, the skull is perfectly sized and aligned to the “horns” (retroarticular processes) present on the body plate. This seems incredibly difficult to achieve in a fossil of this size. This specimen was prepared in the US and I have no reason to believe the skull is fake, but the uniform spacing and shape of the teeth also looks off to me. That may just be due to incomplete preparation of the area, I can’t tell even under 10x magnification. In any case it’s beautiful to look at, I was just a little disappointed to see that it may be a composite. What are your thoughts?

I bought this fossil about a year ago and have had it sitting in my display cabinet front and center. It was sold to me as Vetulicola, it came from the Chiungchussu formation in Chengjiang, China. I was wondering if this is actually a Vetulicola species or a similar animal from the formation. It is right at 1cm in length, and the details seem pretty good up close. If it is Vetulicola, is it possible to assign a species to this specimen? Any help would be appreciated!
