Sauropods even less likely to sit on their eggs. The eggs I have
been working on, although I haven't been able to do any work on them
in the last year, were laid in an alluvial setting and covered by
sediment. This I assume would protect the eggs against the direct
heat of the sun and keep them at a ?little varying temperature. I
undertand that there is some evidence elsewhere that nests were
covered by vegetation to allow the warmth of the decomposing plants
to keep the eggs warm. As for dinosaurs sitting on eggs, I guess it
depends on how much the body was covered in feathers. I can imagine
a _Tyrannosaurus_ squating down on some eggs like an ostrich if it
had the feathers to protect them..... unlikely though?
