Scientists have found the fossilised stays of a brand new species of duck-billed dinosaur that roamed Chile 72 million years in the past.

Dubbed Gonkoken nanoi, the plant-eating creature weighed as much as a tonne and will develop to 4m (13ft) in size, in line with analysis printed in Science Advances.

The discover follows an nearly decade-long investigation.

In 2013, an expedition led by the Chilean Antarctic Institute (INACH) uncovered fragments of yellowish bones on the backside of a hillside near the Torres del Paine nationwide park in Patagonia.

Jhonathan Alarcon, the principle creator of the research, stated: "At first, we thought it was from the same group as other South American hadrosaurs, but as the study progressed, we realised that it was something unprecedented."

He stated researchers needed to delicately extract greater than 100 items of bone, taking care to not harm others within the course of.

Following this, palaeontologists had to ensure the stays belonged to the identical species and test them with current analysis to confirm that it was a brand new type of dinosaur.

Another research creator, Alexander Vargas, stated: "[The] Gonkoken nanoi is not an advanced duck-billed dinosaur, but rather an older transitional duck-billed lineage - an evolutionary link to advanced forms."

The in depth analysis allowed scientists to digitally reconstruct the skeleton - and so they're now planning to create a 3D print so it may go on public show.

Gonkoken is a mixture of two phrases from the language of the indigenous Aonikenk folks, who inhabited Patagonia till the tip of the nineteenth century.

"Gon" means comparable or just like and "koken" means wild duck or swan.

"Nanoi" is in recognition of Mario 'nano' Ulloa, a former rancher who supplied the staff with help through the first discoveries.
