A recovery trilobite association after the end-Ordovician mass extinction, the 'Encrinuroides' Association, is documented from the lower Niuchang Formation (upper Rhuddanian, lower Llandovery, Silurian) of Gaojiang, Meitan, northern Guizhou, South China paleoplate, including 10 genera of eight families. Three subassociations of this association could be differentiated, i.e., ascendingly the 'Encrinuroides'-Eoleonaspis Subassociation, the 'Encrinuroides'-Aulacopleura (Paraaulacopleura) Subassociation, and the 'Encrinuroides'-Meitanillaenus Subassociation. The succession of these subassociations in the section indicates a shallowing upward trend of the environment as a result of regional tectonic activities (i.e., the Qianzhong Uplift) against the background of the Rhuddanian global transgression. A relatively complete trilobite succession in South China across the Ordovician Silurian transition has been summarized and its implications for the trilobite macroevolution of this particular time interval are discussed in detail.
