Marine connections in North America during the late Maastrichtian: Palaeogeographic and palaeobiogeographic significance of Jeletzkytes nebrascensis Zone cephalopod fauna from the Elk Butte Member of the Pierre Shale, SE South Dakota and NE Nebraska

Abstract:

The Elk Butte Member of the Pierre Shale of southeast South Dakota and northeast Nebraska yields a late Maastrichtian cephalopod fauna of nautiloids, belemnites and ammonites of the Jeletzkytes nebrascensis Zone, best known from the near-shore facies of the Fox Hills Formation.
