Late Silurian and Early Devonian brachiopod species are listed from two new sections in the Royal Creek area, Yukon. The data from these sections fill in knowledge of the biostratigraphy of brachiopods of Late Silurian (Ludlovian and Pridolian) and, more importantly, of early Zlichovian (late Early Devonian) ages, of the northern Cordillera.Thirteen species of brachiopods are described in this study, five (none new) from the Late Silurian, and eight from the early Zlichovian (late Early Devonian), of which species of Phragmostrophia, Linguopugnoides, Vagrania, ?Salairina, and Metaplasia are probably new, but have not been given formal species names.
