Abstract: The first two known occurrences of limestone in Johore State are reported from the Sungei Sedili and Sungei Lenggor areas. The calcitic, locally carbonaceous limestone in the Sungei Sedili area covers about ¼ square mile, while the Sungei Lenggor occurrence is smaller. Both occurrences are fossiliferous, and fossils from the Sungei Sedili indicate a Permian age.
