Crazyhen Posted February 26, 2018 Share Posted February 26, 2018 Any idea if these are dinosaur eggs or concretion. The inside is completely crystallized like quartz. It is from Ganzhou, Jiangxi of China. 1 Link to comment Share on other sites More sharing options...
Fruitbat Posted February 26, 2018 Share Posted February 26, 2018 They look more like some type of geode to me. -Joe Illigitimati non carborundum Fruitbat's PDF Library Link to comment Share on other sites More sharing options...
Troodon Posted February 26, 2018 Share Posted February 26, 2018 This picture was taken in the Heyuang dinosaur museum at Guangdong China. So guess a geode like crystallized structure is possible in dinosaur eggs. 8 Link to comment Share on other sites More sharing options...
jpc Posted February 26, 2018 Share Posted February 26, 2018 To be able to say yes to dinosaur eggs we need clear pix of the texture of the surface and the cross section where it is broken. 3 Link to comment Share on other sites More sharing options...

Auspex Posted February 26, 2018 Share Posted February 26, 2018 Certainly geodized, but whether there is an organic origin cannot be told from the pictures. 1 "There has been an alarming increase in the number of things I know nothing about." - Ashleigh Ellwood Brilliant “Try to learn something about everything and everything about something.” - Thomas Henry Huxley >Paleontology is an evolving science. >May your wonders never cease!

HamptonsDoc Posted February 26, 2018 Share Posted February 26, 2018 Eggs can have crystallization like you posted above. In Terry Manning's Egg and Embryo Project many of his Therizinosaur eggs had crystallization like what you posted. The size of the eggs look similar to the ones you posted. Most likely these are authentic but do need some better pictures of the shell to confirm. You can see some of the crystal structure in the image below. 7 Link to comment Share on other sites More sharing options...
Troodon Posted February 26, 2018 Share Posted February 26, 2018 Looks very much like shell material and appears to be of consistent thickness all around which is typical of eggshell. Not sure you would see that with geodes. The outer shell structure is also very similar to the museum clutch I posted, not quite you normal preservation where you can clearly see the ornamentation on the shell. They are pretty rough and may be a result of the environment that caused the crystals to grow. 5 1 Link to comment Share on other sites More sharing options...
Auspex Posted February 26, 2018 Share Posted February 26, 2018 I am bothered by the 'matryoshka doll' aspect, where the 'shell' edge diverges, and seems to make an egg-within-an-egg. This would be pretty unusual for an egg, no? 4 "There has been an alarming increase in the number of things I know nothing about." - Ashleigh Ellwood Brilliant “Try to learn something about everything and everything about something.” - Thomas Henry Huxley >Paleontology is an evolving science. >May your wonders never cease!

Troodon Posted February 26, 2018 Share Posted February 26, 2018 Definitely not normal but it could a side piece pushed in since it's not a clean break. Something to look at if we get further pictures. I don't see it in the other two specimens they still gives me a shell appearance. 2 Link to comment Share on other sites More sharing options...
HamptonsDoc Posted February 26, 2018 Share Posted February 26, 2018 Agree with Troodon- likely that is a piece of shell the got pushed down into the egg sometime after the egg was laid. 1 Link to comment Share on other sites More sharing options...
Nimravis Posted February 27, 2018 Share Posted February 27, 2018 Here is a dinosaur egg portion that I have in my collection and it also has crystals- not positive on the place of origin. TOP PORTION: BOTTOM PORTION: 6 Link to comment Share on other sites More sharing options...
RyanDye Posted February 27, 2018 Share Posted February 27, 2018 Well, looking at all of this so far, you might of actually found a dinosaur egg! I highly suggest to take some better pictures of surface, but if you have the surface it would be highly likely a dinosaur egg is what you found. Congrats!

steelhead9 Posted February 27, 2018 Share Posted February 27, 2018 I recently prepped several very similar eggs that were totally crystallized inside. In the photo of your first egg I see potential embryonic material in the upper right portion of the egg. Still Life Fossils Link to comment Share on other sites More sharing options...

It would be hard to find one of those pieces of shell for that much. I'm beginning to think skipping Tucson and going straight for your MAPPS show is in order. Sounds like you are pulling incredible bargains from there. Link to comment Share on other sites More sharing options...

Auspex Posted February 28, 2018 Share Posted February 28, 2018 I do not think the thickness is as consistent as it should be for egg shell... 1 "There has been an alarming increase in the number of things I know nothing about." - Ashleigh Ellwood Brilliant “Try to learn something about everything and everything about something.” - Thomas Henry Huxley >Paleontology is an evolving science. >May your wonders never cease!

Troodon Posted March 1, 2018 Share Posted March 1, 2018 I think Auspex has raised so good points with that specific egg that additional closeup photos may help resolve. Any chance of seeing them? Link to comment Share on other sites More sharing options...

Any chance of seeing them? Unfortunately this one was sold and I don’t have any more photos. But would that thicker part be a result of matrix not removed completely? 1 Link to comment Share on other sites More sharing options...
