Buenaspis is a genus of small ( 1 to 3 centimetres (0.39 to 1.18 in) long) nektaspid arthropod, that lived during the early Cambrian period.^[1] Fossil remains of Buenaspis were collected from the Lower Cambrian Sirius Passet Lagerstätte of North Greenland. Buenaspis looks like a soft eyeless trilobite. It has a headshield (or cephalon) slightly larger than the tailshield (pygidium), and in between them six thoracic body segments (somites). The genus is monotypic, its sole species being Buenaspis forteyi.
