Full Title: Biostratigraphic Classification of the Marine Triassic in North America
Authors: N.J. Silberling and E.T. Tozer
From the original catalog copy: Ammonoid faunas representative of every major part of Triassic time occur at one place or another in the marine Triassic strata of western and arctic North America. Various local sections, where parts of the faunal sequence are preserved, have been pieced together in overlapping fashion into a unified sequential framework of biostratigraphic units presented in an annotated zonal chart. This zonation for the first time provides an objective and reasonably detailed standard of reference for expressing the age and correlation of the marine Triassic rocks of Canada and the United States.
