di-NO-tyrannus

["Tommy Bradley" <htomsirveaux@mybluelight.com>]

Okay,
     I don't wanna start anything (the last thing in the world I'd want is to 
agrivate anybody :-D), but what's the deel with Dinotyrannus?
Is it the senior synonym of Albertosaurus megagracilis?
IS it a junior subjective synonym of A. megagracilis?
Is it valid?
Is it INvalid?
Or has it become include it with T-rex?
Or is it's validity (as so often is the case) strictly a matter of opinion?
And is it classified under Tyrannosauridae Incerte Sedis, or Tyrannosaurini?
     Any help would be greatfully apperciated.
     Oh and one more thing:

Dinotyrannus [Olshevsky vide Olshevsky, Ford & Yamamoto, 1995]
     D. megagracilis [Paul, 1988 vide Olshevsky, 1995]

Is that right?  I just wanna make sure I got who named what and when right.
     Thanks again,
     Tommy
