The discovery of the type species, Vegavis iaai, demonstrates that the major groups of bird alive today had already diversified in the Cretaceous. This supports the longstanding phylogenetic inferences of paleornithologists.[citation needed] It has been hailed as the first definitive physical proof that representatives of some of the groups of modern birds lived in the Mesozoic.[1]

  • The discovery of the type species, Vegavis iaai, demonstrates that the major groups of bird alive today had already diversified in the Cretaceous. This supports the longstanding phylogenetic inferences of paleornithologists.[citation needed] It has been hailed as the first definitive physical proof that representatives of some of the groups of modern birds lived in the Mesozoic.[1] The Vegavis fossil specimen is held by the Museo de La Plata, Argentina. The specimen, cataloged as 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 fossil.[1] Alan Feduccia of the University of North Carolina has dismissed the specimen an "unidentifiable bundle of bones" and has taken issue with using one specimen he claims to be possibly misidentified as evidence that the Anseriformes cohabited with dinosaurs.[2] Feduccia's claims about the origin and evolution of birds are rejected by the majority of dinosaur experts[3] and ornithologists.
