Abstract | The present paper focuses on “Faunal Assemblages of the Middle Jurassic Samana Suk Formation, Chichali Gorge Section, Surghar Range, Sub-Himalayas-Pakistan”. The Samana Suk Formation is a carbonate sequence of the Middle Jurassic age and is widely distributed in the Upper Indus Basin, northern Pakistan. This formation belongs to the Baroch Group and is mainly comprised of limestones, which were thought to be a prospective fossils archive. The Samana Suk Formation with a primary thickness of 43.27m is exposed at the Chichali Gorge Section. A total of 108 limestone rock samples were collected from 51 beds. The formation was investigated by a detailed petrographic analysis to ascertain its faunal assemblages in the Chichali Gorge Section. These investigations revealed that the limestones of this formation are a good repository of faunal fossils. The fossil contents found in the Samana Suk Formation display a wide range of faunal species. The documented species are comprised of: foraminifers, gastropods, pelecypods, bryozoans, echinoids, sponges, brachiopods, and corals.
