The Deerhope Formation of the Pentland Hills, near Edinburgh, is generally considered to be of late Telychian (late Llandovery) age (e.g. Robertson 1989; Bull & Loydell 1995; Clarkson et al. 2001). Evidence for a precise level in the graptolite biozonation has, however, thus far been lacking. The only published record of graptolites is that of Mykura (1960, p. 166) from the Deerhope Burn. Clarkson & Taylor (2002, p. 32) described this material as comprising ‘rare unidentifiable monograptids’. Bull & Loydell (1995) described graptolites from the underlying Reservoir Formation, exposed in the Gutterford Burn, and assigned the assemblage to the middle part of the Oktavites spiralis Biozone. The author has recently examined all of the Deerhope Formation fossils housed in the British Geological Survey collections. These collections contain a small number of biostratigraphically significant graptolites that form the subject of this short paper.
