摘要：
Two ammonoids, Guanlingoceras guanlingensis n. gen. n. sp. and Neoprotrachyceras sp. are described from the late early Carnian (Julian 2) Xiaowa Formation of Guizhou province, China. Guanlingoceras guanlingensis n. gen. n. sp. is characterised by ventral spirals which are duplicated with small nodes and robust spines arranged in an alternating pattern. These discoveries further not only enrich the ammonite biodiversity in South China but also indicate the age of Xiaowa Formation should be assigned to Julian 2
