Definitely.  For many genera and species, it comes down to the eye of the 
beholder.  Some , like _Kakuru_ or _Xiaosaurus_ or _Titanosaurus_ or 
_Megalosaurus_ are on the bubble: their validity is a matter of differing 
opinion.  Others are no-brainers: _Antrodemus_, _Agathaumas_, _Pteropelyx_ 
and _Paleoscincus_ (and so many others) fall into the category of undisputed 
_nomina dubia_.

Which might well be true.
