Abstract
Palynological studies of the mainly terrestrial Edmonton Group in Alberta, Canada have been undertaken for the last 64 years. The Edmonton Group is of Late Cretaceous (Campanian–Maastrichtian) age and was deposited on the northwestern fringes of the regressing North American inland sea. Satish K. Srivastava initiated the detailed palynological study of the Edmonton Group, publishing many papers on the taxonomy and biostratigraphy of this unit. Subsequent palynological studies have produced significant additional information about the biostratigraphy of these strata. The accumulated data on lithostratigraphy, magnetostratigraphy and radiometric dating have allowed for a better understanding of the group. Satish K. Srivastava formalized many species from the Edmonton Group and a list of type specimens is provided together with new curation information. All of the microscope slides have been transferred to the collections of the Royal Tyrrell Museum. Neotypes and lectotypes are herein designated and illustrated for 21 missing original type specimens. Wodehouseia edmontonicola is emended and new combinations are proposed for Expressipollis catterallii, Siberiapollis major and Corrugatisporites verrucosus. The ranges of selected species provide an updated biostratigraphy for the Edmonton Group.

Satish K. Srivastava sadly passed away during the stage of addressing reviewer's comments and these revisions were subsequently handled by Dennis R. Braman. Professor C.R. Stelck supervised Satish K. Srivastava's M.Sc. and Ph.D. theses. Satish K. Srivastava acknowledges the help and supervision received from Charles R. Stelck in collecting samples and in field guidance on the stratigraphy, without which the M.Sc. and Ph.D. projects would have been impossible for a newly arrived student from India in 1964. Stelck also introduced Satish to the slippery Canadian bentonite by letting him slip on a slope after a drizzle, instructed him how to roll underneath barbed wire fences after wrapping a flak jacket around, and demonstrated goose and pheasant hunting although Satish never took up shooting except by still cameras. The late Don Taylor accompanied Satish in most of the field trips and assisted in collection of the samples. His acumen in the field was something to marvel at. Rosalind Srivastava arranged and cataloged all the slides produced during the last 40 years, and read the manuscript for errors and omissions. The slide collection traveled well from Edmonton to Vancouver to California and back to Royal Tyrrell Museum, Drumheller, Alberta. David Eberth provided input into the stratigraphic relationships of the Horseshoe Canyon Formation. Discussions with Art Sweet over the last three decades have contributed greatly to our understanding of the biostratigraphy and taxonomy of the Late Cretaceous and Paleocene palynology of the Western Interior Basin. The Royal Tyrrell Museum of Palaeontology has supported the collection and study of samples from the Edmonton Group by Dennis R. Braman. The authors thank the efforts of Len Hills and Art Sweet, whose comments greatly improved the content of this paper.
