Habelia is a genus of extinct arthropod from the Middle Cambrian. Its fossils have been found in the Burgess Shale in British Columbia, Canada. Fifty-four specimens of Habelia are known from the Greater Phyllopod bed, where they comprise 0.1% of the community.[1] While previously enigmatic, a 2017 restudy found that it formed a clade (Habeliida) with Sanctacaris, Utahcaris, Wisangocaris and Messorocaris as a stem-group to Chelicerata.[2]
