Regarding the issue of head crests and feeding behavior:

The presence of a head crest would also preclude the tyrannosauroid
_Guanlong_ from scavenging.  If a crest/no-crest is a criterion, then I
don't buy it.  _Guanlong_ probably enjoyed sticking its snout deep inside
carcasses.  _Guanlong_, _Dilophosaurus_, _Ornitholestes_, and other
crested meat eaters probably did just fine at scavenging.  They just had
to improvise a bit.  Step #1:  Turn head to the side. Step #2: Stick head
in cavity of torso.  Step #3: Start eating.  Step #4: When removing your
head from cavity, make sure your head is turned to the side.
