_megagracilis_ Paul 1988 (orignally placed in _Albertosaurus_) is the type
species of _Dinotyrannus_

...it's widely considered a junior subjective synonym of _Tyrannosaurus_ (and
_megagracilis_ a junior subjectice synonym of _rex_). IOW, the holotype of
_Dinotyrannus megagracilis_ (=_Albertosaurus megagracilis_) is widely
considered a subadult _T. rex_

Better:
_Dinotyrannus_ Olshevsky vide Olshevsky, Ford & Yamamoto, 1995
    _D. megagracilis_ (Paul 1988) Olshevsky vide Olshevsky, Ford & Yamamoto,
1995
    = _Albertosaurus megagracilis_ Paul 1988
