Discovery of the Day: Fossilized Bones of Largest Known Dinosaur Discovered in Argentina

Paleontologists from the Museum of Paleontology Egidio Feruglio have unearthed around 150 fossilized dinosaur bones, representing seven of what's believed to be the largest known dinosaur to have ever walked the Earth, in the desert about 135 miles west of the city of Trelew in Argentina. The seven are currently thought to be a new species of titanosaur, a group of particularly tall and heavy dinosaur herbivores.
