I see your point for most of this, and I certainly don't claim to have stumbled 
on "THE TRUTH".  

Let me clarify, that when I say "dawn theropod" I am talking about critters 
like Eoraptor and it's ancestors.  If I understand the theory correctly, BCF 
applies to theropods that lived considerably after Eoraptor died out (Protoavis 
being a benchmark).  Or, does BCF apply even to the most "primitive" of 
theropods?

Then, is bipedalism simply a feature of an arboreal lifestyle?
