Walchia

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.W. hypnoides: from the schists of Lodeve; also copper slates of the Zechstein in Mansfeld.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.
