What structural characteristic contributed to Arsinoitherium looking bulkier than its height suggested?
A very deep chest and broad back supported by sturdy legs
Although its height was comparable to a large modern rhino, the visual impression of Arsinoitherium was one of overwhelming density and volume, largely due to its structural configuration. It possessed a build characterized by a remarkably deep chest cavity and a broad back structure. This robust torso was essential for housing the internal organs necessary to sustain its 2,600 kg mass and process substantial amounts of vegetation. Furthermore, its legs were not built for sustained running; instead, they were configured as sturdy columns, specialized precisely for supporting massive vertical loads. This combination resulted in a creature that appeared low, powerfully built, and immensely dense relative to its measured vertical height.
