In this title, the morphology, evolution, and paleoecology of the highly successful Silurian atrypide spire-bearers is described in detail, including the documentation of several new species. Numerous detailed illustrations and plates accompany the text. This report details the morphology, evolution, and paleoecology of the rich & well-preserved Silurian atrypoid brachiopods found on the island of Gotland in the Baltic Basin and in the Anglo-Welsh Basin, United Kingdom. It includes information about the field & laboratory methods used in investigating these fossil species, historical background on research into atrypid species since the mid-1700s, an outline of the stratigraphy of the study areas & the distribution of atrypid species within the various strata, and clarification of the internal structure of over 45 species. The largest section of the report is devoted to a systematic paleontology of the species studied, including documentation of several new species.
