Officials from the Argentine Museum of Natural Science dubbed the prehistoric creature Bicentenaria Argentina. 

Researchers said the carnivorous beast was likely to be measured between 2.5 and 3 metres (8 and 10 feet) long and was slim and agile. 

Palaeontologist Fernando Novas said the dinosaur represents a new line line leading to the evolution of modern day birds. Novas said: 

"The Bicentenaria isn't one of the biggest dinosaurs, it is approximately 2.50 metres (8 feet) long, but it is part of a group that ends up with the origins of gigantic creatures like Tyrannosaurs and others that aren't so big like the Velociraptor and ultimately those feathered dinosaurs with long arms but that are actually quite small which are birds."
