Thanks to all, but...

I still need the weights of these magnificent beasts.  Rough estimates 
are okay, but the closer the better.  I don't mean like "2 tons, 485 
lbs. and 6 oz." type stuff, just "2-3 tons" or the like will be okay. 
And by the way, I already did try looking for the information here at 
the library and on the net, but to no avail.  Glad for your help, and I 
would like some typical pack/herd size, types of prey/vegetation eaten, 
height from the ground, best guesses at skin coloring, etc.  Thanks 
again,

Derek

P.S.  If you all would be so kind, could I also have the time periods 
these dinosuars came from as well?  Peace.
