Researchers have discovered a first-of-its-kind dinosaur from the extinct great sauropod family 'Diplodocidae' in South American country of Argentina. The members of Diplodocidae family of dinosaurs are known for their huge bodies and extremely long necks and tails.

Researchers led by Pablo Gallina of the Fundacion Azara (Universidad Maimonides) said that the newly discovered dinosaur species, Leinkupal laticauda, is a relative of Diplodocus and Apatosaurus dinosaurs.

Sharing the discovery, Gallina said, "The discovery of a new sauropod dinosaur species, Leinkupal laticauda, found in Argentina may be the first record of a diplodocid from South America and the youngest record of Diplodocidae in the world."

The lead researcher added that the new diplodocid sauropod dinosaur had been identified from the early Cretaceous period in Patagonia.

Researchers detected differences between this species and other species found in North American and other parts of the world in the vertebrae portion where the tail links to the body. This difference prompted the researchers to give a new name to this species.

The discovery was published in the most recent edition of journal PLOS ONE.
