Which two regions define the known longitudinal extent of the Coelodonta antiquitatis distribution?

Western Europe and the Bering Strait region

The Woolly Rhinoceros was geographically extensive across the northern parts of the Old World during its time of dominance. Fossil evidence and paleontological records confirm a vast range spanning across the massive expanse of the mammoth steppe. Specifically, documented fossil beds indicate that the distribution stretched substantially from the western edges of the continent, encompassing areas like Britain, all the way eastward across Siberia to the far reaches near the Bering Strait region, which connected to East Asia. This widespread presence underscores their success in inhabiting the broad, open grassland ecosystems stretching across northern Eurasia. While presence varied in density and duration—for instance, being longer in Siberia than Western Europe—these two points define the major longitudinal boundaries of their historical territory.
