Paleontologists heralded the discovery of a previously unknown small armored dinosaur in southern Argentina, a creature that likely walked upright on its back legs roaming a then-steamy landscape about 100 million years ago.
The Cretaceous Period dinosaur, named Jakapil kaniukura, would have been well-protected with rows of bony disk-shaped armor along its neck and back and down to its tail, they said. It measured about 5 feet (1.5 meters) long and weighed only 9 to 15 pounds (4-7 kg), similar to an average house cat.
