Giant deer — Megaloceros giganteus

Geologic period: Quaternary — Late Pleistocene

Age: The Smithsonian Deep Time specimen from Ireland lived approximately 15,200 to 11,100 years ago.

Taxonomic note: Despite the nickname 'Irish elk,' Megaloceros was a deer and ranged far beyond Ireland.

Feeding: Herbivorous.

Evidence: The skeleton and antlers are direct fossil evidence. The exact balance of display, competition and other selective pressures on antler evolution remains interpreted.

Why it matters: Megaloceros provides a powerful example of Ice Age megafauna and of how spectacular structures evolve under ecological and reproductive pressures.

Plain Language Identity: A giant Pleistocene deer of Eurasia, often misleadingly called the Irish elk.

What You Are Looking At: A complete mounted skeleton bearing the enormous antlers of Megaloceros giganteus.

Ecosystem: Late Pleistocene Eurasian grassland and open woodland ecosystems.
