Research help

[lmeeks1977@comcast.net]

Hello All,
I was wondering if any of you could direct me to any information for the 
following animals:
Deinochyus - including espeically anatomy, muscle structure, 'pack behavior', 
paleobotanical environment
Eionosaurus (spelling I know, shame) - a ceratopsian which I find fascinating. 
Same kind of information, anatomical structure, habitat, diet if possible, herd 
potential.  
I am doing research for a painting and want to be as up to date and accurate as 
posssible, such as, the big question, would these two animals even co-exist?  
Thanks for your help,
Lisa M.
