Crazyhen Posted November 30, 2017 Share Posted November 30, 2017 My friend found a clutch of fossil eggs from Qujing, Yunnan. The eggs are about 4cm in size and it is a large clutch. Any idea what species does the eggs belong to? Link to comment Share on other sites More sharing options...
Aurelius Posted November 30, 2017 Share Posted November 30, 2017 I'm not at all convinced they are eggs, they look like concretions. Can't see any shell or anything like that. Link to comment Share on other sites More sharing options...
izak_ Posted November 30, 2017 Share Posted November 30, 2017 I agree with Aurelius. @Troodon Thats a lot of eggs for one clutch Link to comment Share on other sites More sharing options...
oilshale Posted November 30, 2017 Share Posted November 30, 2017 Looks more like concretions not eggs. I don't have a geologic map of China at hand, but I think Qujing, Yunnan is more Silurian to Devonian and not Jurassic or Cretaceous. Too old for dinosaurs and also too old for vertebrate eggs that size. You could only find fish eggs.

Crazyhen Posted November 30, 2017 Author Share Posted November 30, 2017 Could concretion resulted in so many tightly packed egg shaped rocks? Link to comment Share on other sites More sharing options...
westcoast Posted November 30, 2017 Share Posted November 30, 2017 Very interesting piece. Caliche nodules or pisoliths come to mind. These are nodules associated with fossil soil horizons. They can be very abundant. More details about the location would help. Link to comment Share on other sites More sharing options...
Troodon Posted November 30, 2017 Share Posted November 30, 2017 Cannot see any eggshell material which would say geologic especially if its Devonian in age. However if you can examine the nodules closely and determine if any eggshell is present need to reassess our thinking. Link to comment Share on other sites More sharing options...

Rockwood Posted November 30, 2017 Share Posted November 30, 2017 There is a definite structure in the lighter colored material. We may be zoomed in enough for it to be crystalline though. Sponge ? Link to comment Share on other sites More sharing options...

steelhead9 Posted November 30, 2017 Share Posted November 30, 2017 Here is a small egg I am just finishing prepping of similar size. I would suggest that POSSIBLY I am seeing a similar texture on the closeups in the darker material. The lighter colored areas could be calcite that would need to be prepped off. Not at all sure about this, but worth a look. On the other hand, the irregular shapes would seem to indicate that these are in fact concretions. 1 Still Life Fossils Link to comment Share on other sites More sharing options...

No, it doesn't feel sticky when I touched them with wet finger. A few more photos of the "egg" after I made it wet. Link to comment Share on other sites More sharing options...

Sagebrush Steve Posted December 1, 2017 Share Posted December 1, 2017 Are the black areas just on the surface of the rock or embedded within it? Can you scratch them off? Reminds me of manganese dendrites but the pattern is not consistent with classical dendrites. Link to comment Share on other sites More sharing options...

It's also rather soft that I can use my fingernail to scratch it. Link to comment Share on other sites More sharing options...

abyssunder Posted December 1, 2017 Share Posted December 1, 2017 (edited) You can take one of those eggs and cut it half. It might be interesting to see how it looks inside. Also, are the "eggs" of the same dimension? If they are, that might exclude further hypotheses.
