Find the world's largest dinosaur fossil bone

American biologist archaeologists have found a fossil bone of the world's largest dinosaur in the United States (when it grew to 18m long and weighed 30 tons).

The Rockies Museum in Montana and the Pennsylvania State Museum (USA) described the process of collecting two giant vertebrae and one femur of archaeologists in New Mexico from 2003-2006 in a paper newspaper.

Based on the bone sample, the researchers believe that this is the bone of short-legged dinosaur named Alamosaurus sanjuanensis. And is a Jurassic plant-eating long-necked dinosaur in southwestern America and Mexico, about 69 million years ago.

With this new discovery not only demonstrates plant-eating dinosaurs, Alamosaurus is the world's largest dinosaur native to North America.

Earlier, many other important archaeological relics have been excavated in the last 10 to 15 years, including new species of animal populations such as carnivorous dinosaurs with short legs and long tails that have lost many teeth while eat the body of the Alamosaurus dinosaur.

Recent findings by paleontologists at the Rockies Museum also point to important evidence of the growth and growth of dinosaurs during prehistoric evolution.

In addition, finding the bones of the world's largest dinosaur eating Alamosaurus plant opens up new research into the origins and maturation of dinosaurs in very different animal worlds.
