An exceptionally preserved fauna within dolomites of the Friars Point Limestone Formation includes the most diverse brachiopod assemblage yet described from the Tournaisian of the British Isles, and the first from Wales. Each of the 16 brachiopod genera includes a single species, of which four are new (Schellwienella cheuma, Schuchertella subcrona, Composita ptygmation, Fusella extrata). Associated fossils are corals (one species), bryozoans (two species) and crinoids (one species). Spiriferoideans and schizophorides are numerically dominant, indicative of level-bottom, inner mid-ramp biotopes. Biogeographical comparisons reflect the cosmopolitanism of early Carboniferous brachiopod generic assemblages. Taxonomic comparisons involve selection of lectotypes for Syringothyris exoleta North, 1920, Syringothyris cyrtorhyncha North, 1920, Tylothyris laminosa beta North, 1920, and Tylothyris laminosa gamma North, 1920.
