As Sligo archaeologist Sam Moore explained, Abbeyquarter and other "boulder circles" are considered to bepassage tombs because of other contextual evidence: "Some have Carrowkeelware, pins, pendants, stone balls, cremations, inhumations, animal bones, and some similar Carrowmore ones do have rudimentary passages. Hence, their grave goods resemble passage tomb type assemblages." (email, July 28, 2022).
