Summary:
The world's oldest and most primitive duck-billed dinosaur, dating back more than 95.5 million years, has been discovered by paleontologist Jason Head of the Department of Geological Sciences in Southern Methodist University's Dedman College of Humanities and Sciences. Discovery of the specimen near Flower Mound in North Central Texas will require that dinosaur researchers re-think the long-held notion that duck-billed dinosaurs originated in eastern Asia more than 90 million years ago, predicted Head, whose findings are being published in the current issue of the Journal of Vertebrate Paleontology.
