Bibliography and Index of Paleozoic Crinoids

The purpose of this volume is to list all systematically treated or illustrated Paleozoic Crinoidea for the years 1986 through 1990. Initially it was planned to include the Coronate Echinoderms; however none were illustrated or systematically treated during the 1986 through 1990 interval. This volume continues and updates GSA Memoir 137, Bibliography and Index of Paleozoic Crinoids 1942-1968 (Webster, 1973); GSA Microform Publication 8, Bibliography and Index of Paleozoic Crinoids 1969-1973 (Webster, 1977); GSA Microform Publication 16, Bibliography and Index of Paleozoic Crinoids 1974-1980 (Webster, 1986); and GSA Microform Publication 18, Bibliography and Index of Paleozoic Crinioids and Coronate Echinoderms 1981-1985 (Webster. 1988).
