Kohol on the southern edge of the Atlas Mountains in Algeria. They come from the third layer of the El-Kohol Formation and date to the Middle Eocene. The rather extensive finds include a skull, a lower jaw and remains of the musculoskeletal system. A much older find from the Lower Eocene is known with a lower jaw fragment from a phosphate mine near Tamaguèlelt in northern Mali. However, this belongs to a much smaller representative and may have to be assigned to a different taxon. Further dental finds were found in connection with a rich fish fauna from Ad-Dakhla in Western Sahara and can be assigned to the transition from the Middle to the Upper Eocene. Paleobiology The construction of the nasal bone with the elongated outer nasal cavities suggests the presence of a short proboscis in Numidotherium. <ref name="Shoshanietal1996"/ The early proboscideans are commonly associated with a semi-aquatic way of life, as proven in the closely related Barytherium and in Moeritherium. The fused bones of the forearm support this view, but the plantigrade structure of the forefoot shows adaptations to terrestrial locomotion, just as the low position of the eyes speaks against a water-dwelling way of life. The low-crowned molars with their typical, clearly formed lophodontic chewing surfaces indicate specialization in relatively soft vegetation, which should have predominantly included leaves, fruits and twigs. The fibrous food was probably looked for on bushes at head height or just above it, characteristic grinding marks on the anterior premolars suggest that the animals wedged them in the mouth and tore them off with lateral movements of the head. Isotope analysis of the teeth confirm this assumed terrestrial way of life. In the case of Numidotherium compared to Barytherium or Moeritherium, these resulted in more fluctuating ratios of the oxygen isotope O18, which in the latter two are significantly more balanced due to their semi-aquatic way of life. It is possible that an adaptation to life in a semiaquatic environment occurred several times within the Proboscidea, whereby the question remains unanswered as to whether the proboscis, including today's elephants, actually descended from some water-dwelling ancestors.<ref name="mahdoubietal2014"/ The traditional postcranial skeleton of Numidotherium allows conclusions to be drawn its concerning locomotion. Due to the arrangement of individual joint surfaces in the shoulder and pelvic area and the fused bones of the forearm, slightly bowed limbs can be assumed. The bones of the front and
