Fossilied musculature of an early Cambrian cycloneuralian animal
Oxytropidoceras posted a topic in Fossil News
Early Cambrian microfossils preserve introvert musculature of cycloneuralians The open access paper is: Zhang, H., Xiao, S., Eriksson, M.E., Duan, B. and Maas, A., 2023. Musculature of an Early Cambrian cycloneuralian animal. Proceedings of the Royal Society B, 290(2008), p.20231803. Yours, Paul H. -
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?

Shown below are 3 different types of dinosaur eggshell, all said to be from the Gaugou Formation in China. The bottom left eggshell is labelled as coming from Dendroolithus, and I am confident in this identification. The other two types are supposed to come from Tarbosaurus bataar (top left) and Oviraptor philoceratops (right) however, and neither of these species are known from the Gaugou Formation, so the question is what they are actually from. Thanks in advance for any suggestions Othniel

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?

A newly described archosauromorph specimen from the lower Middle Triassic from Luoping, Yunnan in southwestern China was found and described as a new species Austronaga minuta. https://en.wikipedia.org/wiki/Austronaga The type specimen is like this: Another look-alike skull is found at the same locality, is it also an Austronaga minuta?

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!

Chinese Dinosaur Partial Leg and Claws --Jiufotang Formation, Chaoyang
FF7_Yuffie posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, what are thoughts on this. A partial leg and claws from Jiufotang Formation. Anyone spot any repairs or reso? Each limb section is approximately 30cm. Seller doesn't know species--a type of Oviraptor? thanks for the help.

The seller said it is a complete unhatched egg from China. 5.5 inches long. It looks weird to me. A fake or something else? Thanks

Hello, A pair of curious eggs from China. 3 inches long, oval shaped. I thought they may be Segnosaur or Therizinosaur, but their eggs are rounder. A small species of hadrosaur, or maybe crocodile? The shell is very thin. The holes in them were caused by chisels during excavation, so they are damaged. But on the plus side, the damage does show how thin the shell is. Would any thoughts.

I have seen on multiple occasions "peccary" teeth for sale originating from the Miocene of the Gansu Province in China. I have never heard of any fossil representative of Tayassuidae being seen outside of the New World, so what might they be? This is a picture of one such "peccary tooth". I'd put this in fossil ID put I thought it was quite a general question.

Real or fake keichousaurus

Hello, I found a seller on online auction site with a lot of cool looking things from northeast China but no IDs for their fossils. The herbivore looks a lot like a sus scrofa piece I have from Florida, I have no thoughts on the carnivore. I'd like to ID before buying if possible. Thanks for any help!

A rangeomorph holdfast trace fossil from the Ediacara formation, Rawnsley quartzite of the Flinders Range, South Australia. This specimen is Medusina mawsoni, so called because it was until recently thought to be a jellyfish, but is now believed to be the attachment point of a fractal rangeomorph as Charniodiscus is the point of anchorage for Charnia sp. This one may have been the holdfast point for some species of Rangea. The diameter of the outer circle is 1.5 cm and the fossil is estimated to be 555 million years old.

Crystalized Oviraptor Egg
Crazyhen posted a topic in Is It Real? How to Recognize Fossil Fabrications
This oviraptor egg is said to be crystalized. The parts with no shell do seem to be agatized (?). Do you think it's a genuine egg? It is from Ganzhou of Jiangxi Province, China.

Is this a notosaur's lower jaw? It is from Yunnan of China. And is it a cervical vertebra at the lower left end of the jaw?

This is a clutch of dinosaur eggs from Gangzhou, Jiangxi Province of China. Note the small egg among the dinosaur eggs. Any idea if the small egg is a turtle egg or what? Sorry the images are not very clear as they were captured from a video.
