Good points. It's indeed striking how small the ilium is in comparison to the 
femur or the vertebral column -- most other theropods, extant and extinct, have 
a considerably larger pelvis. Archie must not have done a lot of running.

> Microraptor also has very large pectoral crest

You mean the deltopectoral crest, right?

I ask just to be sure, because the plesiomorphic condition for tetrapods sensu 
lato is indeed to have separate deltoid and pectoral crests. This is found in 
the better-ossified temnospondyls for instance.

In particular, the femora are crazily long. It looks almost unreal.
