Large Dino Eating Habits

[Amado Narvaez <anarvaez@umd5.umd.edu>]

The thread on large dino growth leads me to ask about how much food a 
full grown Apatosaurus needed each day. I've seen estimates ranging from 
a quarter to a half a ton of leaves, and if I remember correctly, the 
discrepancy is dependent on whether the animal is cold-blooded or 
warm-blooded. What is the current thought on daily food requirements for 
the three familiar sauropods: Apatosaurus, Diplodocus, and Brachiosaurus 
respectively?
