Abstract Cretaceous gastropod molluscs are recorded
from Chatham Island for the first time, represented by rare silicified
species from the Takatika Grit, which has been dated from mollusc,
vertebrate, and dinoflagellate evidence as Campanian (Late Cretaceous)
in age. Species identified comprise Protodolium sp. cf. P.
pittensis Stilwell, 1994 (Neritopsidae); Euspira selwyniana (Wilckens,
1922) (Naticidae); and Eriptycha punamutica Wilckens, 1922
(Ringiculidae), all shallow-water shelf taxa. Coeval, conspecific taxa
are known from the Kahuitara Tuff from Pitt Island, and from the New
Zealand mainland, in comparable shallow shelf habitats.
