Rusingoryx is known for its strange pointed nose with a large nasal dome. This structure represents an instance of convergent evolution with the crests of hadrosaurid dinosaurs, which were used for display and vocalization.^[1][2][3] Studies have shown that the Rusingoryx is a specialized grazing animal, with a preference for arid grasslands.^[4][2] Rusingoryx was migratory.^[5]

The first specimens, which were poorly preserved, were described in 1983, having been taken from a site called Bovid Hill on Rusinga Island in Lake Victoria.^[3][6] Butchered bones found in 2011 with stone tools suggested that they had been killed by humans.^[4][2] In 2016, remains of an additional 26 better preserved individuals were discovered.
