Early Cambrian brachiopods and other shelly fossils from the basal Kinzers Formation of Pennsylvania
An assemblage of seventeen species of Small Shelly Fossils, dominated by the brachiopod Eothele tubulus and species of the mollusk Yochelcionella , is described from the basal Kinzers Formation of Thomasville, Pennsylvania. The occurrence extends southwards the distribution of an Early Cambrian faun...
