Oura is an extinct genus of deuteropodan arthropod from the Cambrian Stage 3 of the Chengjiang Lagerstätte, located in the Yunnan Province, China. It contains a single species, O. megale. It is most notable for its large, triangular tailpiece. This tailpiece may have improved Oura's maneuverability.[1]
Oura was named based on a single specimen, YKLP 17237, found in Yunnan Province, China, in the Chengjiang lagerstätte. Some details of the anatomy of this specimen were lost during preparation. The genus name, Oura, comes from the Greek for tail, while the species name, megale, means large (also in Greek).[1]
Description
Oura is roughly 14 cm (approximately 5.5 in) long. The head is divided into six segments, the frontmost of which bears a pair of stalked eyes. The segment of the head immediately behind the frontmost bears a pair of raptorial frontal appendages with at least 3 podomeres (segments). The thorax is divided into 15 segments. Each of these segments bears a pair of appendages, probably biramous (two-branched). The last of these segments bears a very large and wide triangular tailpiece.[1]
