I know that quote.
I've never compared the AvP Queen to a Dinosaur too much, all they got in common is, virtually, them being bipedal and the posture; elsewhere they aren't really comparable if you ask me, even in characterization.
AvP Queen is just bulkier and made to be more of a warrior-kind of
femme. And being bulky and big, bigger thighs help to support that structure (which would fall apart with the original legs).
