Jinbeisaurus (meaning "northernShanxi Province lizard" after Shanxi Province in China) is an extinct genus oftyrannosauroid dinosaurs from theUpper CretaceousHuiquanpu Formation ofShanxi Province in China. Thetype and only species isJinbeisaurus wangi. It is the first non-avian theropod named from Shanxi.[1]
It is known from holotype specimen SMG V0003, including both maxillae, a partial right dentary, two cervical centra, five dorsal centra, and a partial right pubis. It can be distinguished from other tyrannosaurs by several features of the maxilla, teeth, and pubis.[1]
In their 2020 description ofJinbeisaurus, Wu et al. identified the holotype as likely belonging to an adult individual. Theirphylogenetic analysis supported a position more derived than related tyrannosauroids such asXiongguanlong andSuskityrannus but more basal than the Tyrannosauridae.[1] In their 2025 description of the early-divergingtyrannosauroidKhankhuuluu, Voris and colleagues reinterpreted theJinbeisaurus holotype as belonging to a juvenile or immature individual. Their analyses suggested it is an immature form of a late-divergingtyrannosaurine.[2] In their 2025 paper regarding the validity ofNanotyrannus, Zanno and Napoli consistently recoveredJinbeisaurus along withBistahieversor as basalalbertosaurines.[3]
