Research team finds Arctic was dinosaur nursery

Long-standing images of dinosaurs as cold-blooded creatures needing tropical temperatures could be a relic of the past. University of Alaska Fairbanks and Florida State University paleontologists have found that nearly all types of dinosaurs — from small bird-like forms to the giant tyrannosaurus — not only reproduced in the region, but also remained there year-round. Their findings are detailed in a new paper published in the journal Current Biology.
