A team of scientists has named a newly discovered dinosaur “Dreadnoughtus” for its massive size and invulnerability to attack. The 77-million-year-old skeleton, the most complete ever found for a dinosaur of its size, was unearthed in Argentina starting in 2005.
Dreadnoughtus was 85 feet long, stood two stories off the ground at its shoulders, and weighed as much as a dozen African elephants or seven or eight T. rex dinosaurs, according to Lacovara. Skeletal evidence suggests it was still growing when it died.
