Earlier, Graydon claimed that tyrannosaurs were smarter than chickens,
and used a lot of lion/wolf behavioral terminology to describe their
purported social interactions. Since no one really knows the truth to
those claims, I used the only hard evidence available (E.Q. comparisons)
to show that the claims are pure speculation.
I misspoke when I implied that "brain-challenged" creatures don't
interact with each other in complex ways. Indeed, when observed under a
microscope, even brainless bacteria can be seen interacting with each
other when they congregate around a food source. Their communications
are via various biochemical cues.
I think this thread serves a useful purpose in showing that "social
complexity" doesn't necessarily imply "social consciousness". While I
agree that tyrannosaurs were probably quite complex in their interactions
with each other (as are crocs), I also suspect that they were probably
not particularly good at playing "fetch the stick".
Regarding the concept of wolf-like or lion pride-like family units in
tyrannosaurs: We don't even know if tyrannosaur babies were altricial or
Why do chicken coops only have two doors?
Because if they had four doors, they would be chicken sedans.
