ABSTRACT: Jurassic and Cretaceous charophytes of Western Canada (Saskatchewan and Alberta) are known from two narrow stratigraphic intervals and parts of the Bathonian (Middle Jurassic) and Aptian (Early Cretaceous) sequences of the prairie sequences. Thirteen species are accounted for with, twelve from the Bathonian and three from the Aptian. The Bathonian assemblage is one of the richest worldwide, and it provides valuable insight on the earliest phase of the Jurassic-Early Cretaceous radiation of the group.
