Wutubus
Wutubus annularis is a large tubular fossil from the Late Ediacaran of China and USA, between 551 - 541 Ma. It is the only species in the genus Wutubus.
Discovery and name
The first described specimens of Wutubus annularis were found in the Shibantan Member of the Dengying Formation in the Yangtze Gorges area of South China, which dates to 551-541 Mya during the late Ediacaran. Specimens have since been reported in late Ediacaran rocks of the Deep [Spring Formation] at Mount Dunfee, Nevada.The genus name Wutubus is derived from the name of the fossil locality near the village of Wuhe and from the Latin word tubus, to mean tube. The species epithet annularis is derived directly from the Latin word, annularis, with reference to the transverse annulae on the tube.
