My apologies.  I should have clarified that I was curious about
exactly what the most notable of those derived features are.  

What does H. have that makes it more "neotheropodish" than little E.? 
I haven't been able to find these specifics in my sources, and it will
be a few days before I can get my hands on the '93 Nature paper
(assuming, perhaps wrongly, it refers to H. at all...).
