The woolly rhinoceros used its horns for defensive purposes and to attract mates. During Greenland Stadial 2 (the Last Glacial Maximum[8]) the North Sea retreated northward, as sea levels were up to 125 metres (410 ft) lower than today. The woolly rhinoceros roamed the exposed Doggerland and much of Northern Europe and was common in the cold, arid desert that is southern England[9] and the North Sea today
