They can be read about at http://www.dinosauria.com/jdp/trex/hunting.htm, an
article written by Holtz himself. The information probably appeared in a
more scholarly publication as well, but I don't know where. Doubtless HP
Holtz will know the answer.

True. I just realized, upon re-reading the article, that the categories
were meant to apply to LARGE terrestrial hypercarnivores, so that rules out
most of those dinosaurs.
However, _Coelurus_ and troodontids were a fair size. Also, modern volant
predatory birds are included in the "grapple-and-bite" category, so perhaps
_Archaeopteryx_ and _Rahonavis_ cannot be ruled out, being volant themselves
and not too different in size from modern birds of prey.
Anyone know? Tom?
