== Description == Unlike most astrapotheres, Astraponotus was equipped with an unusually high, short, narrow skull. The nasal bones were quite withdrawn, which suggests the presence of a short proboscis. Other unusual features of Astraponotus includes the extreme reduction of the premaxillary and nasal bones, the absence of an antorbital circle, and the reduction of the frontal region. The canines were long and strong, as in all astrapotheres.
