If I'd bothered to read all my new mail first, I would have seen that all 
my points had already been made, sorry about that...
        That fantastic fossil of Velociraptor and a Protoceratops locked 
in combat has the Velociraptor gripping the head of the Protoceratops and 
slashing it's neck. And those arms were pretty well-developed, as well, 
so they would have seen use in gripping the prey. 
One possible problem with a leaping midair attack is that you'd lose a 
lot of force- the force of the kick would push you backwards, while
 standing on the ground prevents this. So does grabbing onto the prey
 And as for those Tyrannosaur forelimbs- those things could pull
hundreds of pounds per arm, they seem to have been used as grappling 
hooks to secure the prey while the tyrannosaur takes a bite out. So they 
certainly weren't vestigial. They do display surprisingly little 
curvature, or at least, I thought so after looking at eagle claws, which 
curve through over ninety degrees.
