Yes, they are off-limits for all time (unless, of course, it is established
that the "junior synonym" really IS a distinct taxon; for example, if it
were established that _Apatosaurus ajax_ (type of _Apatosaurus_) and
_Apatosaurus excelsus_ (type of _Brontosaurus_) were truly distinct at the
generic level (however that might be established), then _Brontosaurus_ could
be used again.
