Phratochronis is an extinct genus of chroniosuchid reptiliomorph from upper Permian (upper Roadian age) mudstone deposits of Dashankou locality, Xidagou Formation of China.[1] It was first named by Jin-Ling Li and Zheng-Wu Cheng in 1999, from a maxilla and premaxilla with almost complete dentition (IGCAGS V 364). The type species is Phratochronis qilianensis. The generic name means “brothers of a clan” (Phrat in Greek) + “late” (chroni) in reference to its taxonomic position, and the specific name referring to the chain of mountains where the type specimen was found.[1]
