Re: Even more concerning the Triceratops/Torosaurus deal

At least one Torosaurus frill is known from Canada. So it is not possible 
for just T. prorsus to be north of the border while T. horridus was only in 
the U. S. growing up to be Torosaurus. 

I have to wrap up the Princeton U Press dinofield guide right now, so must 
try to figure out how to go on this without misleading the readers late next 
year when the book comes out.

species each had a Toro adult stage? >>
