Exceptionally preserved fuxianhuiids from the Cambrian （Stage 3） Hongjingshao Formation in Kunming,southern China

Recently,Nature published a paper （Nature 2013, 494： 468--471. ） entitled ＂Specialized appendages in fuxianhuiids and the head organization of early euarthropods＂, by Prof. Zhang Xiguang and coworkers from Yunnan University. The newly discovered Xiaoshiba Lagerstatte from the early Cambrian （Stage 3） Hongjingshao Formation of Kunming is associated with many articulated trilobites, which are representa- tives of either later Qiongzhusian or early Canglangpuian.
