Pure musings on my part...
Let's say for a moment that dromaeosaur claws weren't the killer-katanas as was
first thought. What evolutionary pressures would select for longer claws? One
answer could be linked to their origin: aboreal theropods. What if the claws
are simply innovations that allow the group to more easily maneuver in the
treetops? A while back, someone (Mickey?) suggested that dromaosaur claws
could have acted like lumberjack boot-spikes, allowing the animal to climb up
the trunks of trees. Admittedly, the idea of an animal the size of
_Utahraptor_ up a tree seems rather unstable; yet if a gorilla can maneuver
safely in a tree, then I guess it isn't totally impossible for _Utahraptor_.
If this is true, the dromaeosaur-superpredator model goes bust (kinda takes
some of the fun out of life, huh). ;^)
