The dinosaur found in Argentina may be the oldest dinosaur ever



Researchers from the country’s National Science Council believe that the fossilized Titanosaurus roamed in present-day Patagonia at the beginning of the Cretaceous period 140 million years ago.

This new analysis means that Titan dinosaurs (a diverse group of long-necked, plant-eating dinosaurs) lived longer than previously thought.

Pablo Gallina of the National Council for Science and Technology Research (Conicet) said: “Except for the fossil being a new type of Titanosaurus, the main importance of this fossil is that it is the world’s The oldest in the group.”

;

He added that 140 million-year-old fossils are “very scarce indeed.”

The specimen was discovered seven years ago in the province of Neuquen in northwestern Patagonia, according to paleontologist Sebastian “Al Ninja” Apestegia and technician Rogerio · Zapata is named “Ninjatitan zapatai”.

It is the oldest Titan dinosaur ever and is also considered the largest.

Although the fossil is incomplete, its pelvic bones and vertebrae indicate that Ninjatitan zapatai is about 20 meters long. Its close relative, Andesaurus, grows to 18 meters.

The largest animal that ever existed is still the blue whale, which can grow to 33.5m.

When the dinosaurs became extinct at the end of the Cretaceous period 65 million years ago, the Titansaurus was still roaming.
