During which epochs did *Arsinoitherium* thrive, according to fossil dating?

Answer

Late Eocene and early Oligocene epochs

*Arsinoitherium* existed during a specific window of time characterized by warmer, wetter global climates before significant cooling. The fossil record places its active period spanning the late Eocene and extending into the early Oligocene epochs. Quantitatively, this timeframe correlates roughly to the span between 36 and 27 million years ago. This placement is crucial as its eventual disappearance aligns with the climate shifts that concluded the Oligocene.
