How far posterior are you talking about. It looks like the 3rd maxilary 
might be recurved, and the 4th is for sure. Maybe it's just my eyes, but if 
I was to call any of the teeth leaf-shaped, 12 and further back would be my 
choice.
Also, on _Eoraptor_, there appears to be a significant overhang over the 
antorbital fenestrae, more prominant on the left side, but visible on the 
right. Is this due to (possible?)compression of the rest of the skull, or 
did this really stand out as a shelf in life?
Also, does anyone have the ref. for the description of _Eoraptor_?
