Abstract:
Dinosaur skeletons have recently been found well within the contemporary Arctic and Antarctic Circles. These discoveries have surprised palaeontologists who regarded the dinosaurs as warm-adapted animals. New geological evidence suggests that these polar areas were also rather colder than had been thought and this raises further problems in interpreting dinosaurian palaeobiology: were the dinosaurs fully endothermic and able to survive the darkness and cold of the polar regions, or could they undertake vast annual migrations of 3000-4000 km?
