An unpublished manuscript, entitled The Richmond Group of the Cincinnati Province, compiled by the late William H. Shideler, has been made available by the Division of Geological Survey as Open-File Report 95-1. Dr. Shideler was a professor of geology at Miami University from 1910 to 1957. He died in 1958.

The information in the manuscript was compiled by Shideler over a period of 17 years; he spent five summers during the 1920's in the employ of the Ohio Geological Survey. For 10 years, Shideler annually visited a series of classic exposures of highly fossiliferous Upper Ordovician rocks in southwestern Ohio and made extensive collections of fossils at these sections. From these data he was able to establish extensive faunal lists for each section and compile range charts for various species.

Shideler's typewritten manuscript was edited by Joe H. Marak, curator of the Carl E. Limper Geology Museum at Miami University. Marak notes that the manuscript is outdated, particularly in regard to the names of many fossil species, but will still be very useful to geologists and fossil collectors.

The 96-page report describes 26 exposures of Richmondian rocks in the Cincinnati area and includes an extensive index. Open-File Report 95-1 is available from the Division of Geological Surveys. Credit-card orders may be placed by calling 614-265-6576.
