Judith/Two Med/Horseshoe fauna

[Jeffrey Martz <martz@holly.ColoState.EDU>]

Correct me about the following:

ALBERTOSAURUS:  The once accepted species have been reassigned as follows:

Albertosaurus libratus: THE TYPE (AMNH, 5458 Judiith River Formation) IS NOW 
BACK TO GORGOSAURUS LIBRATUS, A LARGE TOOTHED ALBERTOSAURID LIKE 
DASPLETOSAURUS.  
ALL OTHER specimens attributed to A.libratus ARE ALSO LARGE TOOTHED 
ALBERTOSAURS NOW FLOATING OUT IN TAXONIOMIC SPACE SOMEWHERE (Pharrinj 
suggests assigning them to Dinotyrannus)
     
Albertosaurus sternbergi: (AMNH 5664, FMNH PR308) Considered a juvinile of 
"A.libratus" be Paul (1988): NOW GORGOSAURUS STEERNBERGI.

Albertosaurus arctungunguis: (Horseshoe Canyon) ALSO DUMPED FROM 
ALBERTOSAURUS AND NOT REASSIGNED? Pharrinj suggests assigning these to 
Dinotyrannus as well.  Arte these now under Gorgosaurus arctunguensis 
(TMP 81.10.1?

Albertosaurus megagracilis: (Hell Creek Formation) Now assigned its own 
genus, DINOTYRANNUS

"Gorgosaurus libratus". Alias: "Albertogorgon lambei" (al a Pharrinj), "Big 
toothed gorgo" (al la Bakker).  Includes "gorgosaurus" sternbergi 
(according to Pharrinj).  Dinogeorge suggests affinities to Gorgosaurus 
libratus:  A NEW GENUS OF TYRANNOSAUR?  A NEW 
SPECIES OF ALBERTOSAURUS?  HOW MANY SPECIMENS?  WHERE DOES IT COME FROM?
WAS THIS THING UNDER A. LIBRATUS? WHAT THE HELL IS THIS THING?

Albertosaurus sarcophagus:  STILL VALID 
(Judith River Group &
 Horseshoe Canyon Formation)

DASPLETOSAURUS TOROSUSS: STILL HUNKY-DORY?

BAKKER'S "STRETCH SNOUTED DASPLETOSAUR": What is  THIS?

This is a big mess that I would like soemone to clear up for me, please.
Has anyone published anything on this yet?  Could someone give me the 
reference?  
    I'm getting all this from the "Albertosaur Systematics" thing on Jeff 
Polings Home Page.
