25. They Had To Eat A lot
Some of the most famous dinosaurs that ever existed were giant herbivores and supporting that large frame was a full-time job. Their long necks allowed them to reach up into tall trees where no other animal could reach, giving them a leg up on the competition–kind of like a modern day giraffe! With the extra food source, animals like this could grow to be enormous but in order to do so, they had to consume as much as a ton of food a day, which is equivalent to a bus load of greenery.
