A new and nearly complete skull of Vegavis iaai discovered in Antarctica suggests that modern birds originated before the end-Cretaceous mass extinction.

A 68-million-year-old skull fossil found in Antarctica has revealed the oldest known modern bird, which was likely related to the waterfowl that live by lakes and oceans today, according to new research.

With its glaciers and sub-zero temperatures, Antarctica hardly seems like a place of refuge. However, the now icy continent might have been just that for the early ancestors of today’s living waterbirds –especially after an asteroid slammed into the Earth.

Near the end of the age of dinosaurs, a bird resembling today's loons and grebes dove for fish and other prey in the perilous waters off Antarctica. Thanks to a nearly complete fossil skull, scientists now have identified this waterfowl as the oldest-known member of the lineage spanning all birds alive today.

A near-perfect fossilized skull discovered in Antarctica reveals the bridge between prehistoric and modern birds, a new study has found. The fossil is a specimen of a species called Vegavis iaai, which lived around 69 million years ago – more than 2 million years before the mass extinction that wiped out all non-avian dinosaurs.
