Upper Cretaceous Trace Fossils, Book Cliffs of Utah: A Field Guide

Abstract About 25 types of trace fossils occur in major marine facies of the Star Point and Blackhawk Formations in the Book Cliffs of Utah. Ichnogenera include Ancorichnus, Arenicolites, Aulichnites, Chondrites, Conichnus, Cylindrichnus, Medousichnus, Muensteria, Ophiomorpha, Palaeophycus, Planolites, Rosselia, Schaubcylindrichnus, Scolicia, Skolithos, Teichichnus, Teredolites, Thalassinoides, and Uchirites. Phoebichnus also may be present. Most trace fossils occur in characteristic suites of lithofacies and ichnofacies, which makes them useful in environmental interpretations. The ichnospecies are described herein.
