what I understand in this video and topic that dinosaurs were all overgrown reptiles that lived

under tropical conditions. When we found polar dinosaurs, however, it was driven home to

everyone that dinosaurs could live under different...and thrive under very different climate

conditions.

the helpful climate that it help dinosaurs to born : dinosaur bones near the North Pole.

The animal was called Edmontosaurus, a 35-foot-long, four-ton, duck-billed

plant . The animal was called Edmontosaurus, a 35-foot-long, four-ton, duck-billed plant

eater, a member of the Hadrosaur family, found in 70-million-year-old rock, a mere 50 miles

from the Arctic Ocean, where temperatures can drop as low as minus-60 degrees . According to

conventional wisdom, it shouldn't be here, because this is how dinosaurs are typically pictured:

cold-blooded reptiles living in tropical climes, not in cold, arctic environments like this one. And

the Hadrosaur is not alone.
