MCSDINO built an animatronic Megaloceros Giganteus model. This Megaloceros will be perfectly exhibit in prehistoric park. The bighorn deer lived in Eurasia in the late Pleistocene and early Holocene, from Ireland to the east of Lake Baikal. The bighorn deer went extinct about 7,700 years ago. Megaloceros Giganteus fossils are now on display at the Irish Museum of Natural History in Dublin, Ireland. The Megaloceros is the largest deer. The horns of this ancient deer are surprisingly large. The width of the horn is usually 2.5 meters, so it is called the megaloceros Giganteus.
