Bluesaurus ping.

They had their time. Screw ‘em.

It’s a little known fact that the polar Edmontosaurus went extinct after its primary source of food, the Gretzkidactyl, migrated south to the Los Angeles area.

I question the worth of this study. Like Global Warming, you can create a multitude of theories that isn't true.

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...

Velikovsky and a few others might have a different opinion about how long polar winters were, way back then.

[wildbill]

I’d guess that polar anythings endured cold dark winters.
