Yunnanocephalus yunnanensis (Mansuy, 1912) Trilobite fossil with soft Tissue About 2.5 cm Preserved legs and gills. Lower Cambrian Chengjiang Biota, Qiongzhusi Formation, Maotianshan Shales, Yunnan Province, China I looked at this closer once the specimen arrived last week and I found a whole bunch of gills shown along some other exposed exopods. The item coming out of cephalon top was actually another endopod.
Here is another specimen (whole) just to show you the whole Yunnanocephalus:
