Description
The giant deer, also called the Irish elk, was one of the largest deer ever, with antlers up to 3.6 metres across. Despite its name it was not an elk: its closest living relative is the fallow deer. Many skeletons come from Irish bogs, but the species lived from Ireland to Siberia and only died out after the last ice age.
Habitat
Open grasslands and light woodland from Ireland to Siberia.
