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 paleo- 

 geography for the discerning at what probable depth the Paleozoic sedi- 

 ments were deposited, the shorelines of such deposits, the temperature of 

 the water, the factors indicating faunal provinces, and the effect of cur- 

 rents on the life assemblages. To this end the President of the Society, 

 Prof. Charles Schuchert, secured the cooperation of a number of paleon- 

 tologists, 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.
