== Specimens and species == The only valid species of Nanantius is Nantantius eos, which was first described in 1986. A supposed second species, Nanantius valifanovi, has turned out to be a synonym of Gobipteryx minuta. N. eos was initially only known from an incomplete but elongated tibiotarsus and a cervical (neck) vertebra hailing from the Toolebuc Formation stratum. This holotype tibiotarsus (QM F12992) was found at Warra Station near Boulia, in Queensland.
