Bailongia is an extinct genus of arthropod known from a single species Bailongia longicaudata (longicaudata from Latin: "long-tailed") found in the Cambrian Stage 4 aged Guanshan Biota of Yunnan, China. It was around 5mm long and had a large head shield, nine overlapping tapering tergites and a relatively elongate tailspine. It has been recovered in a relatively basal position within Artiopoda, more derived than Squamacula or Protosutura, but outside Trilobitomorpha or Vicissicaudata.[1]
