Irish elk, (Megaloceros giganteus), also called Irish deer or giant deer, extinct species of deer, characterized by immense body size and wide antlers, commonly found as fossils in Pleistocene deposits in Europe and Asia ...the species was most abundant in Ireland. It was about the size of the modern moose (Alces alces) and had the largest antlers of any form of deer known—in some specimens, 4 metres (about 13 feet) across. Many scientists contend that the Irish elk succumbed to starvation and went extinct during the most recent ice age; however, fossils of M. giganteus uncovered in Siberia have been dated to approximately 7,000–8,000 years ago, a period characterized by warm temperatures. *Britannica.com
