/ˌmɛɡəˈfɔːnə/

very large animals

Etymology
Etymology Information

'megafauna' originates from Greek and Latin, specifically the Greek word 'megas' and the Latin word 'fauna', where 'megas' meant 'great' and 'fauna' referred to animal life (the Latin term is associated with the Roman goddess 'Fauna').

Historical Evolution

'megas' (Greek) and 'fauna' (Latin) were combined in modern scientific coinage in the 19th–20th centuries to produce the compound 'megafauna' used in ecology and paleontology.

Meaning Changes

Initially it meant 'great or very large animal life'; over time the term came to be used more specifically in ecology and paleontology to denote very large-bodied species (including extinct Pleistocene giants) or animals above a given size threshold.
