Panlongia was a small-sized (up to 2 cm) marine arthropod, with an oval-shaped non-calcified exoskeleton. Both the head shield (or cephalon) and the tail shield (or pygidium) are semi-circular. In between the cephalon and pygidium are four thoracic body segments (somites). The cephalon occupies approximately ⅓ of the body length, the thorax ¼ and pygidium about 45%. Panlongia lived during the late Lower Cambrian (Botomian) in what is today South China. In Panlongia spinosa the edge of the exoskeleton carries several small sawtooth-like spines, that are absent in P. tetranodusa.[1]
