Morphologic variation and stratigraphic significance of Triangulatisporites rootsii Chaloner
The morphologic variation in Triangulatisporites rootsii is described and illustrated, and five new varieties (rootsii, irregularis, reticulatus, regulatus, and var. A) are erected. Stratigraphic evidence presented indicates that this species is indicative of Frasnian Age in the Canadian Arctic.
