  Samana Suk Limestone (Pakistan) | |
The Samana Suk Limestone is a Middle Jurassic[2] geological formation in Pakistan, cropping out across the Salt Range from the western side.[1] The formation is thought to have once been a coastal environment. Dinosaur footprints and ammonites found in close proximity support this reading,[4] and the sediments themselves were laid down across three distinct settings: open marine, lagoon and beach.[1]
