Windermeria aitkeni is a Precambrian organism from the Blueflower Formation of Sekwi Brook North, in the Northwest Territories of Canada. Only one specimen has been found. Windermeria is a small (16.4 × 7.9 mm) segmented elongated oval fossil, eight nearly equal-sized segments arranged transverse to medial furrow in opposite arrangement. Windermeria superficially resembles a diminutive Dickinsonia and as such is the only possible dickinsoniid proarticulatan known exclusively from outside of Australia and East Europe.
