1) The evidence for pack-hunting in dromaeosaurids is, at present,\par
restricted to the species _Deinonychus antirrhopus_.  Extrapolation of this\par
behavior to all members of this clade, regardless of size, environment, etc.\par
is as inappropriate as extrapolating pack hunting to all canids because of\par
dholes, wolves, and Cape hunting dogs; to all hyaenids because of the\par
spotted hyena; or to all felids becaues of lions.\par

What evidence do we have that _D. antirrhopus_ had a pack-hunting behavior and what evidence ( or lack of evidence ) do we have that other dromaeosaurids didn't?\par
