A pteraspidid ostracoderm, Althaspis senniensis sp. nov., is described from the Senni Beds Formation of central south Wales. An associated assemblage of dispersed miospores indicates a mid Middle to lower Upper Siegenian age for this fossil. A typical Breconian macroflora is also present. The Dittonian aspect of the ostracoderm supports the suggestion that there is overlap between the Dittonian and Breconian Stages of the Lower Old Red Sandstone.
