Re: Extinction - specific info

[Peter Sheehan <sheehan@csd4.csd.uwm.edu>]

Great list of latest Maastrichtian dinosaurs.  This will be helpful (now 
Norm needs some ranges in esp. Hell Creek).

I would be very interested in your opinion of the following (especially 
the genera) which are listed by Weishampel 1992(in Weishampel a.o. The 
Dinosauria) as being of late Maastrichtian of North America but not in 
your list.  (Page of citation given.)

cf. Chirosenotes sp.  p. 115
?Caenagnathus sp.  p. 115
Sauornitholestes sp.  p115
Montanoceratops cerorhynchus  p. 117
Avisaurus archibaldi  p. 117
?Dryptosaurus sp. p 119
?Lambeosaurus sp.  p. 119
cf. Struthiomimus sp. p 121
?Gryposaurus sp.  p. 123

I realize many of these are probably = to some of the genera you 
recognize, but I would be interested if any of these 9 genera might 
increase the number of genera recognized.
