LOL. They can out run any human if they want.
I don't think elephants can really climb which explains why they are only found in the flat lands...
Here's what I do know... Many Dinosaurs were BIG. They simply meant they can tolerate temperature extremes very well. (see Ice Age mammals).
2nd of all, Dinosaurs were the most successful land animals ever... they reigned for 100 million years. I don't think I'd be too worried about Dinosaur migrating habits... (how much did this study cost the taxpayers?)
and third of all, you have no frame of reference because gravity had to be much less than what it is today. The most an land animal can weight today is what a mature African elephant weights. Any heavier and the Earth's gravity will be so much that you cannot even lift yourself off the ground. And many Dinosaurs were much heavier and bigger than the elephant. The elephants are so heavy... they don't gallop or run... they just do a fast shuffle. I don't think elephants can really climb which explains why they are only found in the flat lands...
My feeling is the the age of giantanism was only allowed by less gravity. And don't even get me started on Pangaea...
Canadian taxpayers. No idea of the cost.
That sounds like something Ted Holden would write.
If you don't know who Ted Holden is, you better do some research before presenting his ideas as anything within a light year of reality.
Or, is this another of his aliases? He has been known to post here under close to a dozen different names, not all of which have yet been found by the moderators and banned.
Oh, please? This sounds interesting....
While Paleontology began as an offshoot of Geology useful for tracking possible petroleum, it has long since turn into a pure science, that is one with no practical economic value at all. It's justification is the same as any other pure research. There are those who don't believe that the government should fund pure research, which is true for Paleontology to the same extent as it is for any other field.
Earth has not gained significant mass since the age of the dinosaur.
What could POSSIBLY account for your idea that there was less gravity 60 million years ago?
