A well-preserved and diverse macrofloral assemblage was recovered from the coal-bearing Carboniferous Barachois Group in Bay St. George Basin, Newfoundland. This assemblage is late Bolsovian in age and is dominated by cordaitean and marattialean tree fern foliage, although medullosan pteridosperms, lycopsids and sphenopsids are also present. The locality constitutes part of the Maritimes Basin, which developed on the southern margin of Laurentia. The strata represents a meandering stream system characterized by sandstones and conglomerates overlain by fining-upwards successions that end in swamp deposits of carbonaceous mudstones and laterally discontinuous coal seams. The distribution and relative abundances of plants within each lithofacies, including miospores, have been integrated with previous interpretations. The paleoenvironmental model shows considerable habitat partitioning between members of different plant groups. Well-preserved cuticles show that the strata have had very little deformation or burial, and are thermally immature.
