100 million years ago, dinos ruled Arctic

Dinosaurs may have roamed among pine trees in the Arctic covered with weird monkey puzzle forests some 100 million years ago, a new study has claimed.
Drawing up the first realistic picture of the fauna in the age of the dinosaurs, researchers from the Royal Holloway University of London claimed that about 100 million years ago, the polar-regions had a climate similar to Britain today.

Just before the extinction of dinosaurs the picture changed again, with magnolia-type trees springing into life brining blossom and scent to the world for the first time, the researchers reported in the journal Geology.

The findings have implications for understanding the long-term effects of global warming, they added.   Research shows that weird monkey puzzle forests covered most of the planet, especially in the steamy tropics.

"Just before the dinosaurs became extinct, all that changed.  Flowering trees similar to magnolias took off, bringing color and scent to the world for the first time."

Studying fossilized tree rings, the team discovered that trees were growing twice as fast as their modern ancestors, with the greatest effect closest to the poles.
