Menteth Limestone Member of Moscow Formation consists of about 30 to 40 cm of thoroughly bioturbated, hard, silty, calcareous mudrock or very silty limestone. Unit separates the Deep Run and Kashong Members. Fossils in the Menteth are dominated by brachiopods and relatively large trilobites. Upper surface includes rugose corals, tabulate corals, and crinoids. The Deep Run-Menteth sequence represents two shallowing-upward cycles. Contact between the two is sharp at eastern and western margins of the central Finger Lakes basin. Age is Middle Devonian (Givetian).
