Hallucigenia is a genus of lobopodian known from Cambrian aged fossils in Burgess Shale-type deposits in Canada and China, and from isolated spines around the world.[4] The generic name reflects the type species' unusual appearance and eccentric history of study; when it was erected as a genus, H. sparsa was reconstructed as an enigmatic animal upside down and back to front.[1] Lobopodians are a grade of Paleozoic panarthropods from which the velvet worms, water bears, and arthropods arose.[5][4]
