Re: Microraptor also ate fish
But would the anaerobic versus aerobic flight muscle osteological
correlates derived from modern birds apply to basal fliers? And I don't know it
can pin down the upper % of microraptor body mass made up of flight muscles to
put a max limit of climb performance that would exclude them from being
able to get into tree canopies from flying from the ground -- assuming the
muscles were strongly geared to anaerobic output (your white breast meat).
looking into of course.

trees etc. even with all anaerobic muscle, then the idea is effectively
falsified, without knowing the actual life physiology. >>
