“It weighed as much as a dozen African elephants or more than seven T. “ Dreadnoughtus schrani was astoundingly huge,” said Kenneth Lacovara, PhD, an associate professor in Drexel University's College of Arts and Sciences, who discovered the Dreadnoughtus fossil skeleton in southern Patagonia in Argentina and led the excavation and analysis. Because all previously discovered supermassive dinosaurs are known only from relatively fragmentary remains, Dreadnoughtus offers an unprecedented window into the anatomy and biomechanics of the largest animals to ever walk the Earth. Its skeleton is exceptionally complete, with over 70 percent of the bones, excluding the head, represented. At 85 feet (26 m) long and weighing about 65 tons (59,300 kg) in life, Dreadnoughtus schrani is the largest land animal for which a body mass can be accurately calculated.
Scientists have discovered and described a new supermassive dinosaur species with the most complete skeleton ever found of its type.
