RE: Rapetosaurus stuff

[rbi <rbi@dana.ucc.nau.edu>]

With Nemegtosaurus now looking firmly entrenched in the Titanosauria, does 
this open up the possibility that Alamosaurus is of Asian origin instead of 
one from South America?  In the Rapetosaurus paper's phylogenetic analysis, 
Alamosaurus is more derived than Nemegtosaurus, but less derived than several 
of the South American titanosaurs.  Also, we have much better evidence of 
faunal interchange between Asia and N. America than we do with S. America in 
the Cretaceous.  Any thoughts?
