Summary

A diverse fauna of trilobites, graptolites, inarticulate brachiopods, sponges, and a worm is described from the Tremadoc rocks cropping out in the Llangynog district, SW of Carmarthen. It permits identification of the Clonograptus tenellus Zone and older Tremadoc strata; younger Tremadoc strata are apparently absent. The fauna shows closest affinities with the Shineton Shales of Shropshire, while some of the trilobites also indicate a close relationship with those from the Tremadoc of NW Argentina.
