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?
