Vegavis is a recently described genus of extinct bird that lived during the Late Cretaceous Epoch ( Maastrichtian Age) in Antarctica, some 66-68 mya. It belonged to the order Anseriformes. Among modern birds, Vegavis is most closely related to ducks and geese (Anatidae), but it is not considered to be a direct ancestor of them.
The discovery of the type species, Vegavis iaai, has been hailed as the first proof that relatives of modern birds lived alongside non-avian dinosaurs.
The Vegavis fossil (MLP 93-I-3-1) was found in the Cape Lamb deposits of Vega Island, Antarctica, in 1992, but was only described as a new species in 2005 because it consists of the very delicate remains of one bird embedded in a concretion which had to be meticulously prepared for study. CT scans were utilized to gain a clearer picture of the bone structure without running danger of damaging or destroying the bones.
