A late Mesolithic flint site of Clark's 'Bann River Culture' is shown on his distribution map at Kirkill, including a single microlith, two broken leaf-shaped arrowheads and tanged flakes now in the Manx Museum.


The flints from Kirkill also contain a Neolithic element, i.e. arrowheads and hollow scrapers, and are listed by P.C. Woodman (quoting Clark), but he locates them on his map in the vicinity of SC 261734 in Malew at Kerrowkeil, possibly in error for Kirkill.
