The Avion locality is a carboniferous lagerstätte in France. This lagerstätte is located in a coal slag-heap outside the town of Avion in the region of Pas-de-Calais. Unfortunately, as this slag heap is closed and no new fossils are able to be obtained outside of the paleobiota previously identified. In addition, the coal where the scraps are obtained has not been assigned to any formation.
