Crazyhen Posted December 3, 2017 Share Posted December 3, 2017 Are these dinosaur eggs? They are from Guizhou, China. About 18cm long. Possibly eggs of Sauropods? Link to comment Share on other sites More sharing options...
ynot Posted December 3, 2017 Share Posted December 3, 2017 Yes they are eggs. Lets see what @-Andy- and @Troodon have to say about them. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough." My Fossil collection - My Mineral collection My favorite thread on TFF. Link to comment Share on other sites More sharing options...
Troodon Posted December 3, 2017 Share Posted December 3, 2017 @HamptonsDoc Look like real dinosaur eggs and very poorly prepped. They are not Sauropod and may belong to a Theropod, it's unknown. They are similar to protoceratopsid eggs but longer and wider. Eggs are described by their eggshell and classified into Oogenera not by dinosaur family. Forgot classification: my guess is Macrooolithus Group E1 1 Link to comment Share on other sites More sharing options...
-Andy- Posted December 3, 2017 Share Posted December 3, 2017 Fascinating. I have never seen this kind of egg from China. Their surface texture and size reminds me of theropod, but I am quite sure they are not the typical Oviraptorid eggs as their shapes are much closer to Prismatoolithus (Troodontinae). I do not see the typical cracking of other Chinese theropod eggs. I have no idea what they are. Thomas Kapitany of Crystal World can give you a better answer. 1 Looking forward to meeting my fellow Singaporean collectors!

-Andy- Posted December 3, 2017 Share Posted December 3, 2017 The eggs look wet. Maybe someone splashed them to highlight their features? And yes, we need to know their size.

The oval eggs are also from Guizhou. Link to comment Share on other sites More sharing options...
-Andy- Posted December 3, 2017 Share Posted December 3, 2017 I don't think there's a way we can accurately ID these eggs without seeing them in person, or contacting an expert in China. The common Chinese dinosaur eggs are either from Henan Province, or Guangdong. Secondly, your eggs are smaller than the average hadrosaur egg, and bigger than the average segnosaur egg.

indominus rex Posted December 3, 2017 Share Posted December 3, 2017 I think that the first oval shaped eggs are theropod eggs and the second image of the cluster of eggs are possibly that of a hadrosaur. I am not sure though. Life started in the ocean. And so did my interest in fossils. Link to comment Share on other sites More sharing options...
Troodon Posted December 3, 2017 Share Posted December 3, 2017 The eggs in last clutch are much too small to be standard hadrosaur type that we see sold but fit dendroolithus or spheroolithus morphology slightly oval and 12 cm. To try to speculate beyond that is a reach since we do not know the specific age or formation they were collected in. I can say it's a very nice clutch that I would love to have them in my collection. Edit: Found this in a paper. Is Ganzhou same as Ginzhou? Nanxiong Fm.: The redbeds of the Nanxiong Basin, Guangdong, may be divided into an upper and lower formations, for the lower section of the Nanxiong Fm. produces such forms as dinosaurs, turtles, and fossil eggs. The upper section's Luofozhai member produces Middle to Late Paleocene Amblypoda. The lower unit contains such elements as Nanhshiungochelys wachingensis, Microhadrosaurus nanshiungensis, Nanshingosaurus brevispinus, Tyrannosauridae indet., Coelurosauria indet., Oolithes elongatus, O. spheroidas, O. rugustus, and O. nanshingensis. Fossil preservation in the Nanxiong Fm. is fragmentary, but undoubtedly the Fm. belongs to the Upper Cretaceous based upon the presence of hadrosaurs and tyrannosaurs. C.C. Young conducted detailed research upon the fossil eggs and believed the egg-producing lithologies at Nanxiong and Ganzhou belonged to the upper Upper Cretaceous.

Troodon Posted December 3, 2017 Share Posted December 3, 2017 Did some research on that formation and a couple of candidates appear and Spheroolthus is a possible candidate for that clutch. Let me point out that the fossil record is not very extensive. 10.1.1.511.9640.pdf 2 Link to comment Share on other sites More sharing options...

HamptonsDoc Posted December 3, 2017 Share Posted December 3, 2017 Wow, where did you find this first pair!?! Andy and Troodon are spot on with their assessments. The first pair looks similar to Protoceratopsid but are a little too big. The largest of the protoceratopsid eggs are about 13-15cm in length (P2 group); these are from the Djadokhta Formation. Can you get more pictures that are close ups of the shell structure and ornamentation? The second group looks Dendroolithius to me. I’m going to vote against spheroolithidae because of the red matrix. I hate the gloss that they covered the nest in. Do you have more close ups of the shell of this nest too? A nest of this size is hard to come by these days! Link to comment Share on other sites More sharing options...

Just changed to spheroolthid since that's what was reported from that formation if that's the proper locality. Both group of eggs are from the same area.

Page 95 in Dino eggs and babies says spheroolithius eggs are found in white and dark grey sands, not red, which is why I voted against it but that may be referring to Mongolian localities, not Chinese.

HamptonsDoc Posted December 3, 2017 Share Posted December 3, 2017 these are some nice eggs. Just be careful if your seller is in China- it is illegal to export fossils from China and you may loose your money and never see the eggs if you chance it.
