New cuticular morphotypes of Cordaites principalis from the Canadian Carboniferous Maritimes Basin
Fossil cuticles were extracted from leaves attributed to Cordaites principalis (Germar) Geinitz (Cordaitales) that were collected from Upper Carboniferous strata in Nova Scotia (Sydney and Stellarton sub-basins) and in Newfoundland (Bay St. George sub-basin). The quality of the cuticular preservatio...
