Fossil woods belonging to the Pinaceae (Pinoxylon albicauloides Greguss, 1954; Picea beaufortense sp. nov.; Laricioxylon occidentaloides sp. nov.; Abietoxylon koreanoides sp. nov.; A. traumatiductus sp. nov.) and a single representative of the Eleagnaceae (Eleagnaceoxylon shepherdioides gen. et sp. nov.) are described and illustrated. Two main conclusions are derived from this investigation. They are (1) the fossil woods of the Beaufort Formation are very similar to the woods of some extant arborescent species of northern North America and northeastern Asia and (2) the fossil flora indicates a temperate climate similar to that of the present-day boreal forest.
