Abstract

Two Permian ammonoid specimens belonging to the genus Kufengoceras are described from the topmost bed of the Laibin Limestone, Guangxi, South China. The ammonoid horizon is just above the Global Stratotype Section and Point for the Guadalupian/Lopingian Boundary. Kufengoceras is a typical Middle Permian ammonoid, and its occurrence above the GSSP supports the previous opinion that the ammonoid faunal changeover took place slightly after the beginning of the Lopingian.
