Re: TRICERATOPS MAXIMUS SKULL PHOTO - GOT IT!

Reposting this since I apparently didn't get all the html's out the last 
time:    
       Yes, I'm quite sure this is the skull that Jim Jensen and Bruce 
Erickson collected in 1963 in Montana and is figured in the field with two 
photos in 
Bruce's _Dinosaurs of the Science Museum of Minnesota: A Curator's Notebook_. 
It appears to be a large horridus, the same as the specimen mounted in the 
Science Museum. Erickson noted in his 1966 paper "Mounted specimen of 
Triceratops prorsus in the Science Museum" (this was before prorsus was made a 
junior 
synonym of horridus) that his mounted specimen (still the world's largest 
mount, 
I believe) represented a sub-adult and suggested the type of prorsus was a 
"runt". He also mentioned a much larger fragmentary specimen from Saskatchewan. 
So this is all old business and suggesting this is a new taxon is a bit 
disingenuous. But that should come as no surprise. DV
