cervical vertebrae in Archosauromorphs

["Ken Kinman" <kinman@hotmail.com>]

Thomas,
     I was just looking at Benton and Allen's 1997 paper on Boreopricea.  
And if I am reading their character table correctly, they show 
Rhynchosaurus, Trilophosaurus and Megalancosaurus as having 7 or fewer 
cervical vertebrae.  I do not know off hand how many cervical vertebrae 
there are in choristoderes.
     However, if I am reading Benton and Allen correctly, Longisquama might 
fit in rather nicely as a basal Archosauromorph in the vicinity of 
rhynchosaurs.
