"Hello droogies -
A few weeks ago I asked if anyone had any comments on
Charles Deemings judgement of oviraptor eggs, with
their large pores, being habitually buriedm but no
answer."
People are on field work I have just come back from Catalonia....
I have received an email from one of the self-exile palaeooologists from our list saying that the Charles Deemings's publication had three claculations erros...However, he never outlined them...
Whereas, I have not been able to go through the whole publication. It would be interesting to know where they are (if they exist), and if they are really mistakes or different calcilational arrangements to suit their theories...
Obviously Charles Deeming opinions here would be greatful...I will try to pursue the self-exile palaeooologist...
"I think their
elongated shape may be
correlated with being buried near the surface, whereas
perhaps more "obovoid" shapes might mean deep burial
or no burial."

Why is that? how could you prove that? Where is the evidence?
"A glance at the layout of the Big Momma nest

seems to me to leave a fair possibility that the eggs
were shallowly buried, with some of the shell very
near or above the surface."

Indeed, but we do not know how they were cleaned etc...
"Sauropod eggs are always rounder aren't they?"

Approximately
" Maybe

have very dextrous egg manipulation capabilities, and

them than deep or no burial."

I do not know about the "very dextrous egg manipulation capabilities", that is difficult to demonstrate.
I know that sauropods could bent their back limbs, so my suggestion is that they laid their eggs and went away!
"If sauropod eggs were not buried deeply, and
presumably not incubated, does this mean they must
have developed in warm conditions?"

There is a bird that has developed an egg that can go without incubation for days!
I am pretty sure they laid their eggs in warm conditions by known the climatic conditions at that time...
"I wonder how many
sauropods have been found in colder climes. I suppose
it's possible they just piled a few leaves on top!"

Or maybe they did have a different mecanism like ostriches!!
