M. Pickford et al., THE DISCOVERY OF LOWER AND MIDDLE MIOCENE VERTEBRATES AT AUCHAS, SOUTHERN NAMIBIA, Comptes rendus de l'Academie des sciences. Serie II. Sciences de la terre et des planetes, 322(10), 1996, pp. 901-906
During diamond mining operations at Auchas Mine, 50 km upstream from O
ranjemund in the Orange River Valley, fossil tree trunks, and vertebra
te bones and teeth have been unearthed. Preliminary investigations ind
