根据中国南方黄芝山剖面二叠纪/三叠纪界线层的新材料，建立了一个新的蛇属——黄之蛇属。通过对其伴生双壳类的区系对比和与邻近梅山剖面混合动物群的地层对比，确定该属的年代为最早的Griesbachian。埋藏学和古生态学证据表明，蛇蛇群的崩溃与一次灾难性事件有关，黄枝沙尼亚被迅速掩埋在生命位置。
A new genus of ophiuroid, Huangzhishania, is created based on new material from the Permian/Triassic boundary beds at the Huangzhishan section, South China. The age of the new genus is constrained as earliest Griesbachian by means of faunal correlation of the associated bivalves and stratigraphical correlation with the Mixed Fauna Beds of the neighbouring Meishan section. Taphonomic and palaeoecological evidence suggest that the collapse of the ophiuroid association was related to a catastrophic event, and Huangzhishania was rapidly buried in life position.
