A new species of Lepidostrobus from the Early Westphalian of South Joggins, Nova Scotia, Canada

A new species Lepidostrobus dawsonii sp.nov., from Langsettian-Duckmantian strata at Joggins section, Nova Scotia, Canada is proposed based on palaeobotanical and palynological study.The new species represents gently tapering, narrow and nearly cylindrical cone fragments the base and apical parts of which are missing.In situ spores are trilete, cingulizonate and of the Lycospora uber-type.This is the first description of a lycopsid fructifications and its in situ spores from the Canadian Carboniferous.Morphology of the cones and spores resembles those of the Czech species Lepidostrobus thomasii Bek & Opluštil from the Intra-Sudetic Basin, which is of the same age but represents a less robust and more cylindrical cone.
