craigory Posted September 11, 2021 Share Posted September 11, 2021 Hi Everyone, First post here... does the dino egg nest in the photos look real? If so, any idea on the type of dinosaur they belong to? Thank you! Link to comment Share on other sites More sharing options...

RJB Posted September 12, 2021 Share Posted September 12, 2021 To me it looks real, but in purty bad shape. RB 1 Link to comment Share on other sites More sharing options...
Troodon Posted September 12, 2021 Share Posted September 12, 2021 I would like to see closeup of different areas of the nest to see if its all associated. A photo of the back would be advisable. Agree with RB condition is not the best. Eggs are typically not identified to a dinosaur but to a Oogenus (Dendroolithus like your tag indicates) based on many characteristics including size, shape and ornamentation of the eggshell. So what size are these eggs and do you have a provenance on them? 2 Link to comment Share on other sites More sharing options...
craigory Posted September 12, 2021 Author Share Posted September 12, 2021 Thanks! Yes, agree it doesn't look like it's in the best shape but this is all the information I have: Provenance: Nanxiong formation Ganzhou province, China Age: Late cretaceous (100~80 million years ago) Nest size: 20.07 x 16.14 x 5.11inch (51 x 41 x 13cm) Egg size: 4.13~4.33inch (10.5~11cm) Weight: 31kilogram (68.3LB) Link to comment Share on other sites More sharing options...
Troodon Posted September 12, 2021 Share Posted September 12, 2021 I believe the province is Guangdong which is associated with the Nanxiong Fm. Not sure Ganzhou is even one. Without additional photos I cannot make a definitive assessment on this nest. @-Andy- can you tell if Spheroolithius or Dendroolithus ? Link to comment Share on other sites More sharing options...

Troodon Posted September 12, 2021 Share Posted September 12, 2021 Just reacting to you comment "Provenance: Nanxiong formation Ganzhou province, China" Link to comment Share on other sites More sharing options...
FF7_Yuffie Posted September 13, 2021 Share Posted September 13, 2021 With location -- Ganzhou is a city, province would Jiangxi. There is a place in Ganzhou which is part of the Nanxiong Formatiom. 1 Link to comment Share on other sites More sharing options...
-Andy- Posted September 13, 2021 Share Posted September 13, 2021 The locality should be Ganzhou City of Jiangxi province > https://abc7chicago.com/dinosaur-fossil-discovery-oviraptorosaur/10417251/ Unfortunately, neither Dendroolithus nor Spheroolithus are formally described at the Nanxiong Formation. I label mine as Dendroolithus/Spheroolithus because I haven't found any way of identifying either species. Truth be told - they could very well be another oogenus entirely, perhaps even Oolithes indet. 2 Looking forward to meeting my fellow Singaporean collectors!

Truth be told - they could very well be another oogenus entirely, perhaps even Oolithes indet. Thank you - to clarify, are you saying they look real but not Dendroolithus? Or do they look like dendroolithus and the provenance may be inaccurate (not Nanxiong fm)? Are there any books or papers you'd recommend on IDing these? I went ahead and bought them so I'll post more photos when/if I receive them if that'll help with IDing Link to comment Share on other sites More sharing options...

The provenance of Nanxiong Formation looks accurate I don't own the book but 'Eggs, Nests, and Baby Dinosaurs : A Look at Dinosaur Reproduction' was written by Dr Kenneth Carpenter who has experience with dinosaur eggs. From what little sample pages I could read, the book looks to be great at identifying eggs 1 Looking forward to meeting my fellow Singaporean collectors!

Troodon Posted September 13, 2021 Share Posted September 13, 2021 I agree the eggs are real but the photos are not adequate to determine if the clutch is composited. Great book however identification is not going to be easy since like Andy mentioned they have not been described from that formation. It also requires a microstructure analysis of the morphology of the eggshell Link to comment Share on other sites More sharing options...

I got the book more to learn about dino eggs and oogenera in general! I will take some more photos when I recieve the specimen... the seller said that you can see parts of some eggs from the underside as well Link to comment Share on other sites More sharing options...
