The Irish Elk, scientifically known as Megaloceros giganteus, was a massive deer species that lived during the Pleistocene epoch. Its most remarkable feature was its colossal antlers, which could span up to 3.6 meters (12 feet) from tip to tip. Despite its name, the Irish Elk was not exclusive to Ireland but had a wide-ranging habitat across Eurasia.
