Re: Campbell's even crazier than a MANIAC? (archeopteryx
PS: What about the strong trend of cursorial small *crown* theropods
to lose their hallux entirely? It simply works far better with three
toes only. IIRC there is NO living bird, and at best very few extinct
ones, that engage in vigorous running for a living and have anything
but a vestigial elevated hallux. Archie's feet do not look like the
feet of an animal that was good at take-off runs.
Roadrunners are zygodactyl:
I don't see any particular reason to presume that Archaeopteryx could
not run effectively, but I wouldn't expect it to run to launch, anyway.
