Over the past 20 years, South American paleontologists have unearthed several giant species of dinosaurs, including the Argentinosaurus, which is considered to be the biggest dinosaur of all. However, in a report published last Tuesday, it seems that North America now has its’ own species to brag about. Two giant vertebrae and a femur belonging to the Alamosaurus sanjuanensis, a sauropod species, were discovered in New Mexico between 2003 and 2006. Originally, researchers thought that this 69-million-year-old species weighed about 30 tons. Yet the findings from this most recent study showed that the femur discovered belonged to a dinosaur that was still growing, indicating that the Alamosaurus got much bigger than they had ever imagined. This puts the species in the same league as the Argentinosaurus, which weighed about 70 tons and was 40 meters long. Paleontologists are now on the hunt to find more clues about this species’ life, death, and enormity.
