I always wondered how something so HUGE could move on land in our Gravity. When a whale is washed ashore it dies....it can't even breath it's own weight is too much for it. An Elephant can't run...it's bones won't stand the impact stress..the best it can do is a fast walk.
So how about them dinosaurs? What was different?
Different was their long legs :p
like this?
this is like an elephant :D
exactly right...
