RE: Campbell's even crazier than a MANIAC? (archeopteryx climbing)

Perhaps it's about time to settle this experimentally; BUILD an
Archaeopteryx or Microraptor, and see what it can do. Robotic, surgical,
developmental or genetic modification, or detailed simulation in silico; all
worth a try, and there ought to be some Hollywood money to throw at the

 I'm confused, is this debate about whether or no dromaeosaurs could climb
trees, or perch on branches? These are two different things. An animal can
be well adapted for climbing and not be able to perch as birds do. So the
issue of whether or not dromaeosaurs could perch is rather irrelevant to
whether or not they could climb trees. Yes, they didn't have a reversed
hallux, but they did have a giant hook designed to dig into things.
Dromaeosaurs also had hands, something birds completely lack. Many smaller
dromaeosaurs, such as archeopteryx, may have simply run up trees. There has
been some interesting work done on this topic.
