Crocodylians are capable of great bursts of speed, sprawling though they
are. Many of their thecodont relatives are considered to have been
capable of bipedal running, probably giving them even greater bursts of
And all this assumes that thecodonts were semi-sprawling; the last time
I checked, they were considered to carry themselves with an upright
gait. Perhaps we can get a list clarification of the latest on this.

All of the current dinosaur books refer to EQ as a *very* rough but
still valuable tool in estimating dinosaur intelligence, so if it's good
enough for Farlow, Bakker himself, et al, it's still worthy of

Many of the extant animals in their phylogenetic bracket (birds,
crocodylians) are certainly social to a greater or lesser extent but do
not exhibit the sophisticated cooperative behavior alleged by the
dancing dinosaur advocates.
