Re: Feduccia on MANIAC

I havent seen any sort of actual phylogeny (I only had access to the text of
the Omni article, but I see there is supposed to be a diagram), but I remember
it suggesting something like,


-Aves was derived from the sorts of "avimorphs" Feduccia et al love,
Longisquama and Megalancosaurus as examples

-there was a monophyletic "herbivore" radiation, composed of ornithischians
and sauropods from that avian stock and

-theropod lineages represent independent flightless radiations from
increasingly derived birdies.

I can post his Omni phylogeny Sunday when I get back to campus (where I have a pdf), but it's basically the standard topology with a few odd aspects (eg. Phytodinosauria). Olshevsky's basal "birds" wouldn't be called birds by almost anyone else. They are just hypothetical small basal archosauromorphs that are arboreal/scansorial and quadrupedal. Archaeopteryx, enantiornithines and such are still theropods in his view. Olshevsky also has a broad/incorrect definition of flight if I recall, including gliding. He doesn't believe flapping flight came about until Maniraptora.


Are there other papers he's written on it that spell it out better?

I don't think so, not in the scientific literature at least. Maybe in some obscure Japanese magazines. But he's a member of Pickering's Yahoo! group http://groups.yahoo.com/group/paleo_bio_dinosaur_ontology/ and regularily tries to defend BCF against critiques by Marjanovic, Williams and others. So you can learn more there by asking him yourself.
