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.

Sixty-six million years ago, at the end of the Cretaceous Period, an asteroid impact near the Yucatán Peninsula of Mexico triggered the extinction of all known non-bird dinosaurs. But for the early ancestors of today's waterfowl,

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.

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

A newly analysed fossil skull settles a palaeontological debate over Vegavis iaai, confirming it as a relative of ducks and geese that lived 69 million years ago
