Résumé
For the last four years, five missions have been led in Bugti territory by the Franco-Baloch team. Thirty fossiliferous localities have been discovered on twelve different levels. The "Bugti Bone Beds", traditionally related to the lower Miocene, are extended in fact from the middle Eocene until to Pleistocene. Numerous new fossils have been discovered including some aquatic vertebrates (sirenians, archeocetes and sharks) and continental (rodents, perissodactyles, artiodactyles, carnivores and primates). Biostratigraphy permitted to establish interrelationships between the different parts of the Bugti basin and to infer the position of the localities into the Indus basin stratigraphy.
