A late triassic flora from east-central Axel Heiberg Island, Nunavut, Canada
A new floral assemblage is described from the Fosheim Member of the Heiberg Formation on southern Axel Heiberg Island. The flora is relatively diverse, consisting of at least 10 different collected species and three field-identified species from a single small locality. The flora has some similariti...

A new floral assemblage is described from the Fosheim Member of the Heiberg Formation on southern Axel Heiberg Island. The flora is relatively diverse, consisting of at least 10 different collected species and three field-identified species from a single small locality.

The largest difference from previously described floras is the dominance of the bennettitalean Pterophyllum astartense, suggesting a drier climate in contrast to the more humid one previously proposed.
