What was the evolutionary need for dinosaurs to be so large?
They probably grew very large because they did not have any real predators. Besides an environmental adaption necessary for survival (some needed long necks to reach plant life, etc.).
The herbivores had predators. Brontosaurus was an herbivore, and it was one of the largest dinosaurs.
Brontosaurus wasn't a real dinosaur. It was the result of two 19th century paleontologists competing with each other. One of them took the skull of one dinosaur and placed it on the bones of another dinosaur (diliphisaurus (sp?))
Brontosaurus is a dinosaur again. http://www.wired.com/2015/04/scientists … ntosaurus/
I figured that somebody would eventually name a new species that name. And why not? Bronte is one of those name people always associate with dinosaurs.
There are number reasons being put forth. The oxygen level was different, the earth was probably greener, and the trees and plants were big, meaning that the herbivores adapted over the years to feed off these trees. Also, there was plenty of food for both herbivores and predators alike. There's a lot of factors that may be at play.
