Unusual, small, round eggs -- from China.

[FF7_Yuffie]

Hi,

 

Does anyone know what these eggs are from? I haven't seen any like these. They are very small--2 inches. From XiXia, Nanyang City,Henan Province. Unfortunately, the condition is poor--with shell missing from one side. But they are quite unique and unusual. They are the first ones like this I have seen for sale. They seem too small to be Dendroolithus. They also appear to be too big for turtle.

 

Edit: Also smaller than Spheroolithus eggs.

 

An offshoot of Dendroolithus/spheroolithus, perhaps--a smaller species that which usually lays those types of eggs. I have seen a similar egg, but slightly bigger, also sold as Segnosaur--but I assume that may be a case of just slapping a probably species name rather than actual scientific basis.

 

Any help would be great.

In the second photo, if that is the actual thickness of the shell, then it is MUCH too thick to be an egg. The first photo looks ok, but the rest look questionable. I am not an expert, so please wait for someone who knows these better than I do to respond.

Thanks very much. The size and shape looks to fall into Paraspheroolithus. Gotta get better pictures of the shell and try and get the shell thickness, though. But it's looking like the best candidate.

 

Cheers.
