News – PH – Titanosaurs found in Argentina may be the oldest dinosaur ever discovered


A colossal dinosaur excavated in Argentina could be the oldest titanosaur ever found, which roamed what is now Patagonia about 140 million years ago at the start of the Cretaceous Period, scientists said on Sunday (Nov. February)

The 20 m long lizard Ninjatitan zapatai was discovered in 2014 in the province of Neuquen in southwest Argentina The University of La Matanza reported on their analysis

“The main meaning of this fossil, apart from being a new species of titanosaur, is the oldest that has been recorded for this group worldwide,” a statement quoted from researcher Pablo Gallina of the Conicet Scientific Council

Titanosaurs were members of the sauropod group – gigantic herbivorous lizards with long necks and tails that were possibly the largest animals to have ever lived on Earth

The new discovery, the statement said, meant that titanosaurs lived longer than previously thought – at the beginning of the Cretaceous Period, which ended with the death of the dinosaurs about 66 million years ago

Fossils from 140 million years ago are “really very rare,” said Dr Gallina, lead author of a study published in the Argentine journal Ameghiniana

The creature was named after the Argentine paleontologist Sebastian Apesteguia, nicknamed “El Ninja” and the technician Rogelio Zapata
