Yes - I should have said "smaller". In other words, smaller than
_Austroraptor_. This is based on a spinosaurid analogy, because spinosaurids
are know to have preyed on small ornithopods, pterosaurs, and
fish. I had this in mind for _Austroraptor_ too. Other dromaeosaurids (the
longer-armed ones) appear to have targeted larger prey, with _Deinonychus_ and
_Velociraptor_ the prime examples of this ecology.

Jeez, that's an interesting idea.

I think so. I'll have to dust off my copy of "Dinosauria II" and check for
