Annotated Catalogue of Grand Canyon Type Fossils Supplement
This supplement to the Annotated Catalogue of Grand Canyon Type Fossils contains six species new to the catalogue, and one entry which was listed as being in Volume 1 but which was inadvertently omitted. The species list of Grand Canyon Type Fossils is also updated herein and is cross-indexed to all three volumes.
The opportunity is taken herein to also update entries for Chuaria circularis Walcott and for Melanocyrillium Bloeser, spp. The updated entry for C. circularis complements Part III of this volume, the annotated bibliography of the world literature on Chuaria. To maintain continuity with Volumes 1 and 2, these entries are retained in the Miscellanea, with reference to the Acritarcha. More discussions on Chuaria will be found in Part III of this volume.
The format followed in Volume 3 is the same as that followed in the first two volumes. The reader is referred to introductory remarks in the earlier volumes for addi onal information.
