I don't think that multi-ton animals should brood their eggs. The eggs
smashed. (Can you believe there was actually some discussion about this
years ago on our list)?! An ostrich egg is remarkably strong, but it
support about 128 kilograms (285 pounds) before it breaks. And please
mind that the large theropod eggs such as _Tyrannosaurus rex_ deposited
been elongate ellipsoid eggs, which would have been considerably weaker
geometric standpoint) than ostrich eggs (which are much rounder).
Perhaps your tyrannosaurs should warm their eggs in some other way.
