@elDino:
Velociraptors also don't look like that. They have feathers. And they're like knee height...
True in packs they could be deadly, but they're not even sure if it was a pack hunter at all. From wikipedia:
"Remains of
Deinonychus, a closely related dromaeosaurid, have commonly been found in aggregations of several individuals.
Deinonychus has also been found in association with a large herbivore,
Tenontosaurus, which has been seen as evidence of cooperative hunting.
[27][28] The only solid evidence for social behavior among dromaeosaurids comes from a Chinese trackway of fossil footprints, which shows six individuals of a large species moving as a group, though no evidence of cooperative hunting was found.[29] Although many isolated fossils of
Velociraptor have been found in Mongolia,
none were closely associated with any other individuals.[23] Therefore, while
Velociraptor is commonly depicted as a
pack hunter, as in
Jurassic Park,
there is only limited fossil evidence to support this theory for dromaeosaurids in general, and none specific to Velociraptor itself."
The 2m super intellegent co-operating Jurassic Park Raptors are uber cool. Sadly reality can be disappointing...
Also they were all in the later cretaceus period, but T Rex and the veolociraptors are still separated by 3 or 4 million years.
