I like this idea, although I'd imagine the fore claws being used
for climbing and the "swivel" foot claws being used as anchors
in a manner similar to the hind feet of cats. This would require
strong neck muscles for the beast to hold the carcass in its
mouth, a la leopard, depending on the size of the carcass. This
may be tenable with smaller dromaeosaur species, but how
many deinonychus would it take to drag a tenontosaur up a tree?
(No, that's not the first line of a joke). If young dromaeosaurs
were independant then perhaps they adopted this behaviour until
they reached adulthood and (presumedly) formed packs capable of
taking down large prey.
        Have any "family" groups of dromaeosaur been found, with
animals at various stages of growth, or are all of the associated
skeletons of adult size?
