Fossils of the dinosaur which lived some 160 million years ago in what is today the Atacama desert, were unearthed in 2009.
They have now been confirmed to be of a rhamphorhynchine pterosaur — the first such creature to be found in Gondwana, the prehistoric supercontinent that later formed the southern hemisphere landmasses.
Researcher Jhonatan Alarcon of the University of Chile said the creatures had a wingspan of up to 2 meters, a long tail, and pointed snout.
“We show that the distribution of animals in this group was wider than known to date,” he added.
The discovery was also “the oldest known pterosaur found in Chile,” the scientists reported in the scientific journal Acta Palaeontologica Polonica.
