The aims of this paper are to provide a list and illustrations of fossils collected from the Mio-Pliocene fluvio-marine and palustral deposits at Wadi Natrun, Egypt, and to describe unpublished material. The focus is on the fossil mammals, but representative examples of other vertebrates are included in order to provide a holistic view of the entire fauna. The fossils are curated in several museums in Europe, the United States of America and Egypt. Because of the scattered nature of the collections it has been difficult to obtain a synoptic view of the fauna, and even though the compilation presented herein is comprehensive, it is surely incomplete, especially regarding the lower vertebrates and reptiles. The literature occasionally provides details of the institutions in which the fossils are curated but the whereabouts of many of the fossils were not divulged and, partly because of this, some of the fossils were thought to have been destroyed during the 2nd World War. However, over 90% of the described mammalian fossils have been relocated and are included in the catalogue. The collection housed in the Cairo Geological Museum is the main focus of the descriptive section of this paper on account of the fact that it contains many undescribed, but nevertheless important, fossils. As a result it is possible to refine the diagnoses of some taxa from the locality, which were hitherto poorly represented, including that of the hippopotamus Archaeopotamus andrewsi, the camelid, Paracamelus aguirrei and the bovids. The first diagnostic remains of the hare from the deposits (Leporidae) are described and the small suid Dasychoerus natrunensis is illustrated along with additional material of the large suid Sivachoerus syrticus. The proboscidean from Wadi Natrun, previously listed as Mastodon sp. by Stromer (1902, 1907a, 1907b) is represented by much of a third molar which indicates that the species concerned is Anancus osiris. The published fossils from Wadi Natrun are re-illustrated, often in stereo, for convenience of researchers interested in the Mio-Pliocene palaeontology of Africa, but because they have already been described, we do not enter into great detail about them.weiterlesen
