That repurposing, which local tradition places in the late 1950s, gives the stone an unusually layered biography: an early medieval object absorbed into a much more recent act of burial, its age and origin set aside in favour of immediate need.

The slab measures 0.9 metres long, 0.35 metres wide, and 0.07 metres thick, and its incised cross follows the Greek form, meaning all four arms are of equal length. The distinctive detail is that these arms are not contained within the face of the stone but run fully to its edges, leaving the ends open rather than enclosed. Scholars of early Irish carved stones will recognise this as a design feature with early medieval parallels elsewhere in the west of Ireland. The slab sits within a cillín, the Irish term for a children's burial ground, a type of site found throughout the country where unbaptised infants and others excluded from consecrated ground were interred, often at the margins of older ecclesiastical enclosures. This particular cillín is associated with the remains of a church at Carrownaseer. A tau cross, a T-shaped stone cross taking its name from the Greek letter of that form, was also present at the site and similarly reused as a grave-marker, suggesting the burial ground drew on whatever early carved stones lay to hand when conventional markers were unavailable or simply not sought.
