Abstract
Permineralized fossil remains of ?dinoflagellates, mosses, ferns, gymnosperms and angiosperms have been found in calcium carbonate concretions from the Eden Main fossil localities, British Columbia, Canada. Fossils come from the Upper Cretaceous Comox Formation of the Nanaimo Group and have been dated as Coniacian in age. A survey of the fossil floral assemblage has revealed morphotaxa of eleven seedless vascular plants from stipes and rhizomes. A new species of 'Paralygodium', a schizaeaceous fern, is described from fertile pinnules. Seven gymnosperm organs are known including a cycadophyte stem, cupressaceous leaves, twigs and cones, and pinaceous leaves and a pollen cone. Twenty-five angiosperm morphotaxa are also currently recognized based on flowers, inflorescences, fruits, and wood. The presence of several taxa with extant relatives that are currently found in the tropics, and abundant fusain indicates that western North America was warm during the Coniacian, probably experienced wet and dry seasons.
