|Restoration of various Megaloceros and Praemegaceros species|
Megaloceros (from Greek: μεγαλος, megalos + κερας, keras, literally "Great Horn"; see also Lister ) is an extinct genus of deer whose members lived throughout Eurasia from the late Pliocene to the Late Pleistocene and were important herbivores during the Ice Ages. The largest species, Megaloceros giganteus, vernacularly known as the "Irish Elk" or "Giant elk", is also the best known.
Most members of the genus were extremely large animals that favoured meadows or open woodlands, with most species averaging slightly below 2 metres at the withers. The various species of the Cretan genus Candiacervus – the smallest of which, C. rhopalophorus was just 65 cm high at the shoulder – are sometimes included in Megaloceros as a subgenus.
Despite its name, the Irish Elk was not related to the elk or wapiti but instead is closely related to the fallow deer genus Dama, and the genus was part of a Late Neogene Eurasian radiation of fallow deer relatives of which today only 2 taxa remain.(Lister et al. 2005, Hughes et al. 2006).
Species in chronological sequence
- M. stavropolensis
- Early Pleistocene species from Southwestern Russia.
- M. luochuanensis
- Early to Mid-Pleistocene species in the Shaanxi Loess of China.
- M. antecedens
- Very similar to M. giganteus, to the point where it is often regarded as a paleosubspecies of the latter. The antlers were more compact, and the tines near the base large and palmate. Lived in Mid-Pleistocene Germany.
- M. pachyosteus
- Mid-Pleistocene China and Japan. Had long, curved antlers.
- M. savini
- Mid-Pleistocene species, slightly larger than a caribou, first fossils found near Sainte Savine, France. Its antlers were straight, with thorn-like prongs. The lowermost prongs near the base were palmate.
- M. giganteus
- Largest, best known, and among the last species of the genus, about 2 m (6.6 ft) at the shoulders. Lived throughout Eurasia, from Ireland to China during the last Ice Age.
