Taxonomy
editArcanotherium was originally described by Court (1995) as a new species of Numidotherium, N. savagei, based on a mandible found in the late 1960s in late Eocene deposits at Dor el Talha, Libya.[1] However, after the Barytherium material from Libya became accessible to paleontologists, undescribed material from the collection prompted Delmer (2009) to erect Arcanotherium for N. savagei.[2]
