Hi,

Thank you very for your question that is very interesting.

I will pass it to the Palaeoological list, you can join us and receive the 
answers.


Unfortunately, this area has not been properly explored unlike other more 
fashionable area of palaeooobiology.

Though, like turtles, the adaptation of incubation to climate chages ( for 
example from aquatic to land ones) would explain a lot theevolutionary 
advantages and disadvantages of calcareous vs. parchment eggs.

In the meantime you welcome to read some of the articles from the book 
below, and my answer to your question.

Deeming D. C. and D. M. Unwind (2004) evolution and the fossil record, in 
reptilian incubation, environment, evolution and behaviour (ed. C. Deeming), 
4-13.



Respectfully,

Perhaps you could explain the evolutionary advantages and disadvantages of 
calcareous vs. parchment eggs.
