Personally, I like the idea of aboreal dromaeosaurs. Yet, I have one concern.
Imagine an animal the size of _Dienonychus_ hanging from the trunk of a tree.
The majority of the weight of the animal would have to be borne by the two
sickle-clawed toes. Were the toes strong enough to bear all that weight?
Wild speculation: Is it possible that the hand claws could have helped at all;
or would the other toes have been of any help?
