Conference of the faunal criteria in Paleozoic Paleogeography
INTRODUCTION The Council of the Paleontological Society voted that at the Second Annual Meeting, held at Pittsburgh, that the greater part of one day should be given to a conference on the faunal criteria of use in paleogeography for the discerning at what probable depth the Paleozoic sediments were deposited, the shorelines of such deposits, the temperature of the water, the factors indicating faunal provinces, and the effect of currents on the life assemblages. To this end the President of the Society, Prof. Charles Schuchert, secured the cooperation of a number of paleontologists, each one being well versed in the topic selected, and December 29, 1910, was selected for the presentation of papers. As the time limit set for each paper was short, the participants could not always give the desired detail on which their conclusions were based.
