Haifengella corona is the only known species of the extinct arthropod genus Haifengella, described in 2014 from the Early Cambrian Chengjiang Lagerstätte in Yunnan, China. It is a helmetiid arthropod closely related to trilobites, notable for its crown-like pygidium (tail shield) that inspired its species name. It belongs to the extinct order Helmetiida within the clade Conciliterga, a group of trilobite-like artiopods[1] Name origin: The genus name Haifengella comes from Haifeng village near the fossil site; the species epithet corona (Latin for “crown”) refers to the crown-shaped outline of its pygidium. Haifengella has six thoracic tergites and two pairs of tail spines.[2] Each of the thoracic tergites exhibits a pair of long spines projecting from the posterolateral corners.[2]
