OverviewExcerpt from The Correlation of Geological Faunas: A Contribution to Devonian Paleontology In the year 1881 I began a series of investigations for the purpose of discovering the laws which determine the association of fossils in faunal aggregates and their modifications in relation to geographical distribution and to vertical succession, in order to apply those laws as guides to the correlation and classification of geological formations. While these investigations have been in progress many other workers have joined in the search. Many statistics have been gathered, and observations have been extended over a wide field. A few important results have been attained, and the nature of the problem is now more clearly understood than at the outset. It seems, therefore, that this is a fitting time to review the progress already made, and to point out the more prominent results achieved and the paths along which future investigations may be guided with most promise of success.
