Dinosaurs could survive cold conditions

Palaeontologists have unearthed a rich variety of dinosaur fossils in an area that would have been one of the most northerly regions of the world in the period just before the giant reptiles died out, between 65 and 68 million years ago.

At the time, the world was far warmer and the continents were still to move to their current positions. Northeastern Russia, where the remains have been found, would have been just 1,000 miles from the North Pole, inside what is now called the Arctic Circle. Average temperatures would have been around 50F (10C).

Fossil hunters found remains of duck billed dinosaurs, fossilised teeth belonging to relatives of the heavily armoured Triceratops and even teeth belonging to relatives of the giant meat eater Tyrannosaurus rex.

The palaeontologists, based at the Royal Belgian Institute of Natural Sciences, also found fragments of dinosaur egg shells alongside the Arctic dinosaur remains, providing the first proof the animals were able to reproduce in these relatively cold, northern climates.
