Hongshiyanaspis yiliangensis *The Xiaoshiba Biota is the second oldest of the four biotas that feature exceptional preservation in the Malong/Kunming area. Many fascinating arthropods have been found in this Lagerstätte, such as Zhiwenia, Alacaris, Chengjiangocaris and Fuxianhuia xiaoshibaensis. It overlies the Chengjiang Biota, and is (in Malong) overlain by the Malong Biota, which yields the widest diversity of trilobite genera (Paramalungia, Yinites etc) of any of the four biot...as.The youngest of the four, the Guanshan Biota, is poorly studied but promises a faunal diversity on par with the Chengjiang Biota. -------------------- Item Details: Location: Near Kunming, China Age: Lower Cambrian, c. 517 mya Formation: Hongjingshao Formation -------------------- Shipping: Will be shipped in 2019!
