The Tenjong Dendang Formation is a geologic formation in Malaysia. The band of graptolite- and trilobite-bearing shales interbedded in limestones preserves graptolite, brachiopod and trilobite fossils dating back to the Hirnantian stage of the Late Ordovician period.[1] The sediments were deposited during the Late Ordovician glaciation.
