A large amount of palynological research has been undertaken on the Late Cretaceous–Paleocene strata of the plains area of southern Alberta. The present study is a summary of the palynoflora encountered in individual rock units across the region. Previous palynological research has been summarized and a brief summary of the geology of the region provided. A large number of taxa have been identified with many not as yet described. Important palynomorph taxa are illustrated along with a tabulation of all the species identified to date for each stratigraphic unit. A biostratigraphic scheme is proposed with 19 biozones described. Not all of these biozones are present in Alberta and information has been taken from materials in Saskatchewan, Canada, and Montana, United States.
