I like to point out that the last refuge for dinosaurs in the world was Alaska. Their age lasted from 252 million to just a mere 66 million years ago.

But this suggests that other Arctic locations might have also been warm enough to support such reptiles.

There were also dinos in the Antarctic, and the climate there was temperate no longer ago than three million years.
