Notoleptos is an extinct monotypic genus of diomedeid bird that lived in Antarctica during the Priabonian stage of the Eocene epoch.^[1]

Etymology

The two parts of the generic name of Notoleptos giglii are derived from the Ancient Greek 'nóto' meaning 'South' and 'leptos' meaning 'gracile'. The specific epithet is in reference to Silvia Moreda de Gigli, the secretary of the Argentinian Paleontological Association from 1987 to 2015.^[2]
