The range of complex motifs consist of abstract 'cup-and-ring marks' of the Galician style found across Ireland, the United Kingdom Western France and Iberia. They consist of deep pecked glyphs produced with a hard tool (probably stone or antler). On the eastern face the motifs are concentrated at the wider northern end of the panel, with a solitary cup and ring positioned at the southern end. O'Nuallain (1978) suggested that the stone may once have been upright, along with a second undecorated stone close by. The motifs include some complex designs incorporating enclosing curvilinear grooves and long radial grooves. Also featured is an unusual spiralling ring enclosing a cup with a radial groove. The cup and rings are arranged across the upper edge of the face, with their radial grooves running parallel directly down the sloping surface. The majority of cup marks are arranged seemingly randomly across the decorated section of the panel. The ring enclosing the isolated cup at the southern end of the panel is considerably thicker than the other rings (this, along with its isolated position, may indicate that it was added at a different time or that this individual motif was accorded greater significance).

No absolute dates are available but generally accepted as Late Neolithic / Early Bronze Age
