	Vegavis - Wikipedia, the free encyclopedia
		Vegavis is a recently discovered genus of extinct birds that lived during the Cretaceous period.
		Among modern birds, Vegavis is most closely related to ducks and geese, but it is not considered to be a direct ancestor of them.
		The Vegavis fossil was found in Antarctica in 1992, but was only identified as a new species in 2004, following the use of CT scans to gain a clearer picture of the bone structure.

		The discovery of a new species, Vegavis iaai, appears to settle the argument, as it has been conclusively dated to 70 million years ago -comfortably before dinosaurs died out.
		Vegavis was found in 1992, but a new analysis of its bones has established it as a distinct species and established its date.
		Julia Clarke, of North Carolina State University, who led the research team, said that Vegavis belonged to the waterfowl family and was "most closely related to Anatidae, which includes true ducks".

	Digimorph - Vegavis iaai (fossil bird)
		Several phylogenetic analyses supported by independent histological data indicate that a new species, Vegavis iaai, is a part of Anseriformes (waterfowl) and is most closely related to Anatidae, which includes true ducks.
		A minimum of five divergences within Aves before the K/T boundary are inferred from the placement of Vegavis; at least duck, chicken and ratite bird relatives were coextant with non-avian dinosaurs.
		The Vegavis iaai holotype specimen from Vega Island, is a disarticulated partial postcranial skeleton preserved in two halves of a concretion.

	Relatives of living ducks and chickens existed alongside dinosaurs more than 65 million years ago
		Information from a new avian species called Vegavis iaai indicates that these birds lived in the Cretaceous period and must have survived the Cretaceous/Tertiary (K/T) mass extinction event that included the disappearance of all other dinosaurs.
		Histological analysis of the bone tissues present in a cross section of a Vegavis arm bone not only indicates that Vegavis was an adult at the time of death but also supports inference of its evolutionary relationships from the independent phylogenetic results.
		The data place Vegavis within Aves, which includes common ancestors of all living birds we have today and all its descendents — that is, the radiation of all living birds — and specifically within one group of Aves called Anseriformes, the waterfowl, which includes ducks, geese and allies.

		Some experts believe that they started to emerge alongside the dinosaurs of the late Cretaceous period, while others insist that bird evolution started only after the extinction of the dinosaurs 65 million years ago.
		The discovery of a new species, Vegavis iaai, appears to settle the argument, as it has been conclusively dated to 70 million years ago ---and comfortably before dinosaurs died out.
		Julia Clarke, of North Carolina State University, who lead the research team, said that Vegavis clearly belonged to the waterfowl family and was “most clearly related to Anatidae, which includes true ducks”.

		But if the new find, known as Vegavis iaai, really is a relative of the duck, it would lend considerable weight to the idea that modern birds lived with dinosaurs and survived whatever catastrophe killed them.
		However Vegavis has not managed to convince supporters of the big bang theory of bird evolution.
		Julia Clarke and her team used a statistical analysis of certain bone features to identify Vegavis as a member of the duck family, but Professor Feduccia is unmoved by their interpretation.

	Anseriformes - Wikipedia, the free encyclopedia
		All are web-footed for efficient swimming (although some have subsequently become mainly terrestrial).
		The earliest known Anseriform is the recently discovered Vegavis, which lived during the Cretaceous period [1].
		It is thought that the Anseriformes originated when two groups of specialised filter feeders diverged from the Charadriiformes (plovers, gulls and allies) by evolving different mechanisims to filter small food particles from water.

		The new analysis of the fossil Vegavis iaai, found in Antarctica in the 1990s, seems sure to ignite controversy.
		But the new research, led by Julia Clarke of North Carolina State University, suggests Vegavis is a direct ancestor of living waterfowl, implying that modern birds evolved alongside dinosaurs.

		Although the first bird, Archaeopteryx, lived in the Jurassic period 150 million years ago, scientists disagree about whether any relatives of modern birds had evolved before the end of the dinosaurs' reign.
		The "duck" species, Vegavis iaai, was from the Cretaceous period which ended 65 million years ago when dinosaurs became extinct.
		Writing in the journal Nature, a team of scientists led by Dr Julia Clarke, from North Carolina State University in Raleigh, said Vegavis belonged to the waterfowl family and was "most closely related to Anatidae, which includes true ducks".

		The evidence is in the form of newly discovered fossilized body parts that comprise the most complete specimen from the Cretaceous that can be linked to living birds.
		The new data show Vegavis is within the group Anseriformes, which includes ducks and geese.

		In a "big bang" theory of bird evolution, these scientists have proposed that relatives of today's birds came on the scene only after non-avian dinosaurs became extinct at the K/T boundary.
