Aaveqaspis is a genus of small (about 2.5 centimetres or 1.0 inch long) marine arthropods of unclear affiliation, that lived during the early Cambrian period.

[1] Fossil remains of Aaveqaspis were collected from the Lower Cambrian Sirius Passet fossil-Lagerstätte of North Greenland.

The upper non-calcified (or dorsal) side of the body consists of a cephalon, 5 thorax segments, and a pygidium.

The back margin of the cephalon from the spine to the midline has in the pleural region a forward angle and is first concave, then convex, then concave again, attaining a backward angle when reaching the axis, and finally convex, with a small node or median spine reaching the back margin.

The frontal border of the tail shield is convex and curves laterally into the large spines which extend postero-laterally, constituting half the total body length.

[1] Its likeness to Buenaspis and Liwia may suggest Aaveqaspis could be assigned to the order Nectaspida and family Liwiidae.
