Devonian Plants from the Type Section of the Ghost River Formation of Western Alberta

Abstract

Plant fossils, including branched axes, foliar structures, fructifications, and dispersed spores have recently been discovered from the type section of the Ghost River formation. The megafossils, although commonly fragmentary, suggest a late Middle or early Upper Devonian age for the beds. This discovery suggests that equivalent strata in other regions may also contain plant remains, the discovery of which would add significantly to our knowledge of Devonian floras in western North America.
