Summary:

Early Permian arthropods from the Sterlitamak Shikhans are represented by trilobites and crustaceans. The relatively diverse assemblage of trilobites was established that includes the following species and forms: Brachymetopus (Conimetopus) alekseevi Mychko, 2019, Paraphillipsia bashkirica (Konstantinenko, 1979), Paraphillipsia sp., Paladin jurezanensis (Weber, 1937), Paladin sp., Kaskia roemeri (Möller, 1867), Kaskia cf. roemeri (Möller, 1867), Kaskia gruenewaldti (Möller, 1867) and Paladin cf. moelleri Frederiks, 1932). Of these, members of the genus Paraphillipsia Tumanskaya, 1930 and form close to Paladin moelleri (Frederiks, 1932) were first identified in the Lower Permian of the Shikhans. Crustaceans include ostracods and cyclidans. The latter are represented by several findingss of carapaces Skuinocyclus juliae Mychko et Alekseev, 2018.
