Last Dino was a Duck Bill...

Aug. 17, 2009 -- One of the last non-avian dinosaurs on Earth was a muscular, swimming duck-billed species that paleontologists recently discovered in Spain, according to a new study that has been accepted for publication in the journal Comptes Rendus Palevol.
Co-author Jose Ignacio Canudo told Discovery News that the hadrosaur, Arenysaurus ardevoli, meaning "sand dinosaur," lived just "a few thousand years before the K/T boundary."
This was the event 65.5 million years ago that wiped out all of the world's dinosaurs, save for a group of carnivorous dinosaurs that evolved into birds.
"Arenysaurus was certainly one of the dinosaurs that might have seen the fall of the K/T asteroid and suffered the consequences," said Canudo, a University of Zaragoza paleontologist.
