RE: Guanlong wucaii (was RE: Early Version of T. Rex Is Discovered)

You took my comment waaaaaaaay to serious. I was making fun of the
resonanting chamber hypothesis of lamberosaurs (since when do animals
make bellowing noises through their nose????) AND Jack Horner's
scavenging hypothesis.

Seemingly illogical given that that would only mean less food for the
'calling' individual. Vultures & bald eagles, for example, don't summon
each other AND they often squabble and/or fight . HOWEVER, it would make
sense if that when groups were assembled they would cooperate in defense
of themselves & the carcass from the [at that time larger
representatives of] other predaceous theropods of the time. This would
also be a good starting point for the socialization that certain
assemblages of tyrannosaurid fossils represent. Besides the obvious
social implications of a head-borne crest that works directly against
predation. . .
