Le Niger est un pays sahélien situé au sud du Sahara en Afrique de l’ouest. Il couvre une superficie de 1267 000 km2 dont les 2 / 3 sont désertiques, il est limité au Nord par l’Algérie et la Libye, au Sud par le Nigeria et le Bénin, à l’Est par le Tchad et à l’Ouest par le Mali et le Burkina faso. Le climat est caractérisé par trois saisons : saison froide (novembre – février), saison chaude (mars – mai) et une saison pluvieuse (juin –septembre.) Les précipitations varient du Nord au Sud avec un isomètre évoluant respectivement de 5O mm à 800 mm sur une période de un à trois mois. Cette irrégularité des précipitations influe grandement sur la production agricole dans un pays essentiellement à vocation agro-pastorale. Sa population est estimée à 12 000 000 d’habitants environ selon le Recensement Administratif 2004 est composée de 9 ethnies réparties dans les huit régions du pays.

Scale [ca. 1:12,250,000]. Covers North Africa and parts of Europe. Map in Latin.The image inside the map neatline is georeferenced to the surface of the earth and fit to the Africa Lambert Conformal Conic projected coordinate system. All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This map shows features such as drainage, cities and other human settlements, roads and routes, territorial boundaries, shoreline features, and more. Relief shown pictorially.

The Early Miocene Napak XV locality (ca 20.5 Ma), Uganda, has yielded an interesting assemblage of fossils, including the very well represented amphicyonid Hecubides euryodon. The remarkable find of a nearly complete mandible, unfortunately with poorly preserved dentition, together with new dental remains allow us to obtain a better idea about the morphology and variability of this species. Additionally, we describe a newly discovered mandible of Hecubides euryodon from the Grillental-VI locality (Sperrgebiet, Namibia), which is the most complete and diagnostic Amphicyonidae material found in this area. Comparisons with Cynelos lemanensis from Saint Gérand le Pouy (France), the type locality, and with an updated sample of the species of amphicyonids described in Africa leads us to validate the genus Hecubides. Hecubides would be phylogenetically related to the medium and large size species of Amphicyonidae from Africa, most of them now grouped into the genera Afrocyon and Myacyon, both endemic to this continent.
