Where are the fossils of *Arsinoitherium* primarily recovered, indicating its primary habitat?
Answer
The Fayum Depression in Egypt
The geological evidence overwhelmingly points to a specific region for the discovery of *Arsinoitherium* remains. The majority of fossils recovered that document this species come from the Fayum Depression located in Egypt. This location strongly supports the interpretation of its habitat as being characterized by extensive swamps, marshes, and lush floodplains, as the region was significantly wetter during the time the animal lived compared to its modern arid state. This moist ecosystem was fundamental to its survival.
