Abstract
Reevaluation of a mandibular ramus and "rib" discovered at Earnscleugh, Otago, New Zealand suggests that the bones are assignable to a gekkonid lizard of gigantic size. The "rib" is consistent in form with a cloacal bone, a feature lacking in other New Zealand lepidosaurian reptiles. A comparison with many gekkonid cloacal bones, including that of Hoplodactylus delcourti, the largest gecko known to have ever lived, indicates that the Earnscleugh lizard was between 275 and 325 mm in snout-vent length. The applicability of the Maori names kawekaweau, ngarara, and kumi to the Otago remains is discussed.
