The Austin Glen Member of the Normanskill Formation is an upper Middle Ordovician unit of interbedded greywackes and shales that outcrops in eastern New York State.[1] It was deposited in a deep marine setting in a foreland basin during the Taconic orogeny.[2] Its sediment source was mainly the erosion of preexisting sedimentary rocks.[2] Graptolite fossils place it in the stratigraphic zones of Nematograptus gracilis and Climacograptus bicornis, but its age could be Llandeilo or Trentonian (earliest to latest Darriwilian, Шаблон:Ma).[2]
