Researchers discover new dinosaur species, oldest giant ever uncovered

Researchers discover new dinosaur species, oldest giant ever uncovered

The discovery winds back the clock on the emergence of giant dinosaurs by a staggering 30 million years - shedding fresh light on their evolution.

"As soon as we found it, we realized it was something different".

The partial fossil, found buried within the southern outcrops of the Quebrada del Barro Formation in northwestern Argentina, consists of several neck vertebrae, a shoulder bone, and several bones from its legs and tail.

"It was enormous. It was at least twice as large as the other herbivores of the time", said lead researcher Dr Cecilia Apaldetti, a palaeontologist from the National University of San Juan. The species "exhibits a growth strategy that was unknown until now and indicates that gigantism originated much earlier than was thought", Apaldetti said. It roamed South America around 210 million years ago during the the Late Triassic. Until now, it was believed it emerged with the appearance of the first sauropods in the Jurassic period.

These were "herbivore dinosaurs, quadrupeds, easily recognizable by their very long neck and tail, and from the sauropod group", she added. I. prima lived about 215 million years ago, a good 47 million years before its long-necked cousins, including Brachiosaurus and Diplodocus, existed, the researchers said. The first ones were small but as they evolved they tended towards gigantism to defend themselves against predators.

Until now, it was thought that giant body sizes in dinosaurs-anything over 10 tons-first appeared around 180 million years ago during the Jurassic period.

While later giant dinosaurs grew in an accelerated yet continuous manner, an examination of its bones showed that Ingentia grew seasonally rather than continuously, but at an even higher rate. The bones discovered by the team displayed cyclical and seasonal growth, and it is believed that the species grew to 26-33 feet tall and weighed equal to two or three African elephants.

Paleontologists made the discovery in Balde de Leyes, an area in western Argentina where other dinosaur species, as well as ancient turtles, iguanas and mice, were previously uncovered. At the end of the Triassic period it was a type of savannah.
