Publication
The occurrence of Apatopygus gaudensis sp. nov. in the upper part of the late Oligocene (Chattian) Lower Coralline Limestone division, and the lower part of the early Miocene (probably late Aquitanian) Lower Globigerina Limestone division of the Maltese Islands (Central Mediterranean), is the first confirmed record of Apatopygus outside the Australia-New Zealand region. Apatopygus vincentinus (Tate, 1891) from the middle to late Eocene of southern Australia is the earliest known occurrence of the genus, possibly suggesting that Apatotygus may have evolved earlier in the Australasian region, or merely that it is yet to be discovered in pre-Oligocene strata in the Mediterranean area.
