Except for those north American populations that specialise in hunting
bison, which tend to be quite large. I suspect that a 10 foot
Deinonychus (half of which, or more, would have been tail) would
have been lighter than the average adult wolf. Wolves don't have
the hollow-boned, avian-like body form that dromaeosaurs seem to have
had. Which begs the question: is that because dromaeosaurs are
decended from flying (or at least arborial) anscestors, where
weight reduction was a necessity? Or was the development of flight
facilitated by the light-weight small theropod design? A chicken
and egg problem, you might say. :)
