DNA from wolf pup’s last meal reveals new facts about woolly rhino’s extinction |
The woolly rhino, Coelodonta antiquitatis, would have been an impressive sight to the ancient people who painted images of them on cave walls and carved figurines of them out of bone, antler, ivory and wood.
The sadly now extinct rhino lived on the steppes and tundra of Europe and Asia, living alongside people for thousands of years. And a new study of woolly rhino DNA, extracted from the stomach of a wolf challenges a long held belief about species at risk of extinction.
The species, which evolved in the middle of the Pleistocene era, approximately half a million years ago, weighed up to three tonnes. It was similar in size to the two largest rhino species alive today, the white rhino of southern and eastern Africa and the one-horned rhino of India.
The woolly rhino was well adapted to live in ice age conditions. It had a thick layer of fat below the skin, a warm, woolly fleece and small ears and tail to minimise heat loss. It also had a shoulder hump to store fat, to help it survive through periods of food scarcity, and a horn that, in exceptional cases, could grow to 1.6 metres in length.
Abrasions on horns have led biologists to suspect that the rhino used its front horn (the species had two horns, like most species........
