Resumen de Goose-like birds survived the dino wipeout
They looked like loons, and are kin to a group of birds that includes geese and chickens. Meet the Vegaviidae, a newly named group of waterbirds that may have lived through the mass extinction that took out the dinosaurs. The Vegaviidae no longer exist, but they are the first bird group known to have survived the extinction, says Federico Agnolin at the Bernardino Rivadavia Argentine Museum of Natural Sciences in Buenos Aires. At the end of the Cretaceous 66 million years ago, a mass extinction--probably caused by an asteroid impact--wiped out many species, including all non-avian dinosaurs. Birds survived, but which groups has been unclear.
