Dinosaur’s Skull--Found Above Arctic Circle--Goes on Display

From Associated Press

A dinosaur’s skull found above the Arctic Circle, a region where the lumbering beast was not previously thought to have roamed, goes on display this weekend at the University of California.

Scientists say the fossil, the fourth species of dinosaur found in the remote, icy area, deepens the mystery of how the great reptiles lived through temperature extremes and months of darkness near the North Pole.

The skull belonged to a pachyrhinosaurus, a name that means thick-nosed dinosaur. It is a smaller relative of the massive three-horned triceratops.
