Re: Re[2]: T.rex arms and Cry...

<<Except that the large sauropods were extinct by the time of T. rex.  It
appears that the only prey rex had to deal with were ceratopians and
hadrosaurs.>>

But there were in North America, at least the one titanosaur _Alamosaurus_
(and I doubt that it was the ONLY one, though finding another species is a
different story); and in Asia, where there were many other species of
Tyrannosaurs (_Maleevosaurus_, _Jinghiskhan_, _Tarbosaurus_, Alectrosaurus_,
and _Alioramus_) AND many species of large sauropods (_Opisthicoelocaudia_,
_Quesitosaurus_, _Nemegtosaurus_, Mongolosaurus_ and lots more).  Maybe,
Tyrannosaurs are native to Asia, and they evolved their short, _strong_ arms
just for the purpose of shoving their heads out of carcasses that they got
stuck in.
