12. Irish Elk (Megaloceros giganteus)
The majestic Irish elk, famous for its immense antlers spanning up to 12 feet, roamed Eurasia during the last Ice Age. Despite its name, it wasn’t limited to Ireland nor closely related to modern elk. This giant deer disappeared around 7,700 years ago, likely due to a mix of climate shifts and human hunting pressure. Its spectacular antlers remain an enduring symbol of prehistoric grandeur and evolutionary extremes.
