Known as the Irish Elk
Megaloceros was a genus of deer found throughout Eurasia from the late Pliocene through the Late Pleistocene [3 million to 8,000 years ago]. They were important herbivores during the Ice Ages. [ Wikipedia ]
The [so-called] Irish Elk was a species of Megaloceros and one of the largest deer that ever lived. Its range extended across Eurasia, from Ireland to east of Lake Baikal, during the Late Pleistocene. The latest known remains of the species have been carbon dated to about 7,700 years ago in Siberia.
Although most skeletons have been found in Irish bogs, the animal was not exclusively Irish.
It was also not closely related to either of the living species currently called elk (the European elk, known in North America as the moose, and the North American elk, or wapiti); for this reason, the name “Giant Deer” is used in some publications. [Wikipedia]
