Abstract: 

The detailed palynostratigraphy established for basins of the Newark Supergroup south of the Canadian border has proven inapplicable to the oxidized, palynologically barren outcrops typical of the Fundy basin of the Maritime Provinces. Dating of the Fundy stratigraphic section has thus been based on lithostratigraphic correlations, radiometric dates, and rare palynomorphs. Palynofloral assemblages recently recovered from an outcrop of the uppermost Blomidon Formation in the Nova Scotia arm of the Fundy basin permit the first correlations with Triassic/Jurassic boundary palynofloras throughout the Newark Supergroup.The well-preserved palyaofloras are all dominated by the genus Corollina, but examination of the less common elements indicates that only those assemblages at the top of the Blomidon Formation, immediately below the North Mountain Basalt, are of Early Jurassic age. These palynofloras contain species that are also present in earliest Jurassic assemblages from the Hartford basin. Palynomorph assemblages 30 cm downsection from the basalt contain rare specimens of the Late Triassic index species Patinasporites densus and an array of monosulcate grains correlative with late Rhaetian assemblages from the Newark basin. Three new monosulcate species (Cycadopites ginker, C. tattoo, and C. schlischii) are described herein.
