A few fossilized body parts hinted at an enigmatic bird's close ties to waterfowl like ducks and geese. A newfound skull may bolster that idea.
Known as Vegavis iaai, the bird thrived in late-Cretaceous Antarctica, then a tropical paradise. About a million years before the asteroid that wiped out 75% of life on Earth, it went extinct.
