A colossal dinosaur dug up in Argentina might be the oldest titanosaur ever discovered, having roamed what’s now Patagonia some 140 million years in the past at the start of the Cretaceous interval, scientists stated Sunday.
The 65-foot (20-meter) lizard, Ninjatitan zapatai, was found in 2014 within the Neuquen province of southwest Argentina, the La Matanza College reported on its evaluation.
“The primary significance of this fossil, aside from being a brand new species of titanosaur, is that it’s the oldest recorded for this group worldwide,” a press release quoted researcher Pablo Gallina of the Conicet scientific council as saying.
Titanosaurs had been members of the sauropod group—gigantic plant-eating lizards with lengthy necks and tails which will have been the most important animals ever to stroll the Earth.
The brand new discovery, the assertion stated, meant titanosaurs lived longer in the past than beforehand thought—at the start of the Cretaceous period that ended with the demise of the dinosaurs some 66 million years in the past.
Fossils from 140 million years in the past are “actually very scarce” stated Gallina, essential creator of a research revealed within the Argentinian scientific journal Ameghiniana.
The creature was named after Argentinian paleontologist Sebastian Apesteguia, nicknamed “El Ninja,” and technician Rogelio Zapata.
