Questions

["Ivan Kwan" <t_rexkwan@hotmail.com>]

I've got a few questions:

1) Does anybody know the names of the other crocodile species recently 
described with Sarcosuchus (mean-looking!). I've been searching like mad, 
but all I can find is Sarcosuchus, Sarcosuchus... and more Sarcosuchus. I'm 
asking this because I really like the painting of Luis Rey of the Suchomimus 
being grabbed by a huge croc, and since the jaw morphology of Sarcosuchus 
does not match that of the croc in the painting (looks a bit more like 
Crocodylus), I'm trying to find another species by which to call it.

2) About the pachycephalosaur referred to as "Sandy", what is its exact 
taxonomic status? Is it Stygimoloch, or is it Pachycephalosaurus? I 
originally thought it was Stygimoloch, (and Luis Rey's painting & 
Pachycephalosauria Home Page seem to state so) However, refers to it as 
Pachycephalosaurus!

3) Anybody got any idea what species the new giant caenagnathid is? Luis Rey 
refers to it as Chirostenotes. (Mike Triebold's page has some really great 
photos!!)

4) I remember that Jack Horner excavated 3 species of Centrosaurine in the 
Two Medicine Formation many years back. One was Einiosaurus, one was 
Achelousaurus, but what is the third species?? It's got a nasal horn like 
Styracosaurus but it has a frill more like Einiosaurus. I tentatively refer 
to it as 'Monoclonius sp.' Any news on its description? It's been a vrey 
long wait because it was discovered some years back and furthermore, an 
entire bonebed of it was found. If Achelousaurus and (one of my fave 
Ceratopsids :) Einiosaurus can be named so quickly, what about this other 
one? (For more info look up Digging Dinosaurs by Jack Horner)

5) Similarly, in Jack Horner's book there is some mention of a tyrannosaur 
somewhat intermediate between Daspletosaurus & Tyrannosaurus. What is it? Or 
what about the supposed 2nd species of Daspletosaurus?

6) Still on Tyrannosaurs, are Shanshanosaurus & Stygivenator still valid 
taxa or are they generally considered juvenile Tyrannosaurus?

7) Is Megaraptor's phylogenetic position settled yet? And what about that 
giant carnosaur that was larger than Giganotosaurus?
