Fw: Feather Flap
Hadn't heard of herbivory being linked to flight evolution before, so the quote
was puzzling; I guess those seeds/gastroliths are the source... I thought maybe
there was a link to a new (to me) theoretical scenario. Thanks.

If people like Scott are right and taxa like Archaeopteryx and Microraptor
with unreversed halluces were still terrestrial, the most basal arboreal
maniraptorans would be jeholornithids and omnivoropterygids. The latter
clades preserve seeds and gastroliths in their body cavities, indicating at
least partially herbivorous habits.
