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.
W. hypnoides: from the schists of Lodeve; also copper slates of the Zechstein in Mansfeld.
At the same time period of 290 mya, another species was making fossil trackways, now preserved in New Mexico; Walchia leaflets are found in the same fossil layers. The Monuran trackways were made by Permian, wingless insects called monurans, (meaning "one-tail"); the insects' means of locomotion was hopping, then walking.
These 290 mya layers contain footprints of the large Dimetrodon, large/small raindrop impact marks, and also these fossil trackways of insects.
