A few years earlier, Rauhut thought that little _Iliosuchus_ (also from 
mid-Jurassic of GB) might also be a tyrannosauroid.  (I should add that 
subsequent studies have been somewhat cool on the idea - although _Iliosuchus_ 
appears to be coelurosaurian at least.)

The name "Maniraptora" is increasingly becoming a misnomer - even among the 
non-avian members of the group.  What's more, it's a real possibility that the 
hypercarnivorous habits inferred for dromaeosaurids like _Deinonychus_ and 
_Velociraptor_ are the exception rather than the rule for maniraptorans.
