Found during a 2011 survey at Cinn Aird Thoir, the piece is an inscribed slab whose original design can no longer be read with any confidence. It might be part of an early Christian cross-inscribed stone, the kind of simple incised marker that appears across Ireland from roughly the sixth century onwards, typically bearing a plain Latin or ringed cross cut directly into the rock face. Or it might be something else entirely, or nothing in particular. The surveyors who recorded it were candid about this, describing the identification as "mere speculation".

The fragment was catalogued by Ann Frykler and Robert Hanbidge of Headland Archaeology Ltd. as part of a graveyard survey conducted in 2011. It was logged under the unglamorous designation Miscellaneous No. 13, which says something about how archaeology handles objects that resist easy classification. Early Christian inscribed stones are not uncommon along the western seaboard, where monastic activity left a scattered material record across headlands, islands, and burial grounds. Whether this piece ever belonged to that tradition is something the surviving evidence cannot settle.
