The Panama Formation (Tp)[1] is a geologic formation in Panama. The formation consists of tuffaceous[2] sandstones, conglomerates, tuffaceous shales and algal and foraminifera-rich limestones,[1] and preserves bivalve fossils of Leopecten gatunensis and Nodipecten sp. and dates back to the Late Oligocene period.[3]
