Dinosaurs Inside and Out

Growing Bones

What is one of the biggest fossil dinosaur bones found to date?

One of the largest fossil dinosaur bones is from the Futalognkosaurus, a titanosaurian dinosaur found in Argentina and described in 2007. This new genus of plant-eating dinosaur was more than 100 feet (30 meters) in length from tail to nose and lived about 90 million years ago. No doubt more such huge dinosaurs will be found in the future.
