The Heavyweight Champion
A study proclaims a newly named species the heavyweight champion of all dinosaurs, making the scary Tyrannosaurus rex look like a munchkin. At 76 tons (69 metric tons), the plant-eating behemoth was as heavy as a space shuttle. The dinosaur’s fossils were found in southern Argentina in 2012. Researchers who examined and dated them said the long-necked creature was the biggest of a group of large dinosaurs called titanosaurs.
