Hallucigenia sparsa
(Maura McCarthy)
Hallucigenia sparsa was originally described by Walcott as a polychaete annelid. Today, Hallucigenia is identified as an armored lobopod — related to today's land-based velvet worms. Hallucigenia gained fame as Stephen Jay Gould’s classic “weird wonder” in his 1989 book, Wonderful Life.
