Palaeobotanical Evidence for The Age of Basal Devonian Strata At Ghost River, Alberta
D. C. McGregor
ABSTRACT
Plant megafossils and spores from near the base of the Ghost River Formation (sensu Greggs et al., 1962) are very similar to late Givetian or early Frasnian species from Spitsbergen, Germany, and the eastern United States. They have little or no similarity to species of the older Devonian "psilophyte floras" of Wyoming and Arizona.
