Re: Brooding rex? (was Feathers for T. rex)
That's interesting, Rob. Perhaps big theropods could lay eggs along
one side of a nest and nuzzle their body up next to the eggs (instead of ON
them). How many eggs were in that huge nest. The more eggs, the more
likely it would be a vegetarian like Therizinosaurus (while meat-eaters tend
to have comparatively fewer young).
I've forgotten what shape therizinosaur eggs are, but the shell
microstructure was not ornithoid (and not very elongate if I recall
correctly). I believe tyrannosaurids probably had eggs pretty similar to
therizinosaurs (segnosaurians), but that is based on my own views of
coelurosaur phylogeny. If they were ornithoid eggs, perhaps a big
caenagnathid laid them?
