Researchers said on Monday the fossils represent a dinosaur species named Ninjatitan zapatai that lived 140 million years ago during the Cretaceous Period. They identified Ninjatitan as a titanosaur, a group of long-necked plant-eating dinosaurs that walked on four pillar-like legs.
The dinosaur's incomplete skeletal remains were discovered in Argentina's Patagonian wilderness, south of the city of Neuquen. The researchers said Ninjatitan demonstrated that the titanosaurs as a group first appeared longer ago than previously known.
"It is the oldest record known, not only from Argentina but worldwide," study lead author Pablo Gallina, a researcher at the National Council for Scientific and Technical Research of Argentina (CONICET), told Reuters.
