Walchia
''Walchia'' is a fossil conifer, cypress-like genus of Upper Pennsylvanian (Carboniferous) and lower Permian (about 310-290 Mya). It is found in Europe; also North America. A forest of in-situ Walchia tree-stumps is located on the Northumberland Strait coast at Brule, Nova Scotia. Besides the ''Walchia'' forest, fallen tree trunks, and leaflet impressions, the forest, fossil-rich layer contains numerous, 4-legged, tetrapod fossil trackways. ==Individual species== ''W. hypnoides'': from the schists of Lodeve; also copper slates of the Zechstein in Mansfeld.
