First record of an Early Ordovician brachiopod and conodont fauna from Lapland, Sweden

An Early Ordovician fauna of linguliform brachiopods and euconodonts is described from the Alum Shale Formation in northernmost Västerbotten County, northern Sweden. The was recovered a single carbonate concretion collected at an exposure near shore Lake Storvindeln. Despite fragmentary tectonized preservation obtained fossils, least eight different taxa four species could be identified. Among brachiopods, ephippelasmatid Pomeraniotreta biernatae Bednarczyk, 1986 most common; it associated among others with acrotretids Eurytreta cf. sabrinae (Callaway, 1877) Ottenbyella sp., spinose specimen potentially representing zhanatellid Thysanotos. Two brachiopod appear to present new species, n. sp. Mytoella? but additional material would needed for formal description. Euconodont specimens are rare comprise coniform elements Drepanodus arcuatus Pander, 1856, Drepanoistodus aff. amoenus (Lindström, 1955) sensu Löfgren (1994), Paroistodus numarcuatus Rossodus manitouensis Repetski & Ethington, 1983. Evaluation stratigraphic distribution under consideration local geology, suggests that investigated sample represents level upper part Tremadocian (Tr2) Formation. occurrence age diagnostic (Tremadocian) fossils
