 In 1989, Scandinavian palaeontologist Solweig Stuenes described "H. madagascariensis" and "H. lemerlei" from these bones.It has been classified as a species of pygmy hippopotamus (genus "Choeropsis" or "Hexaprotodon"), though similarities may simply be due to convergent evolution.Other Malagasy hippos are classified into the genus "Hippopotamus".
