Abstract: A mixed fauna composed of reticulate sponges, inarticulate brachiopods, phyllocarid crustaceans and graptolites is described from the “Foothills formation” of western Pahang State. Graptolites in the assemblage include a monograptid of the M .hercynicus type identified as Monograptus cf. praechercynicus Jaeger. This indicates that the age of the host rock is early Lower Devonian. The fauna has provided the first stratigraphically useful organisms to have been recovered from these rocks. Its discovery implies a Lower Palaeozoic age for the bulk of the “Foothills formation” and underlying schists, and clarifies the structural and stratigraphic position of these units.
