Walchia is a primitive fossil conifer found in upper Pennsylvanian (Carboniferous) and lower Permian (about 310-290 Mya) rocks of Europe and 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.
