"The fossil of a tiny carnivorous dinosaur that lived some 95 million years ago was presented on Wednesday in Buenos Aires by researchers from the National Scientific and Technical Research Council (CONICET). It is Alnashetri cerropoliciensis, a species that lived in northern Argentine Patagonia, in the province of Rio Negro, in the area known as La Buitrera, and belongs to the Alvarezsaurian group. Footage shows the fossil, whose tail represents approximately half of the total body length, exhibited at Maimonides University, as CONICET researchers detail the discovery, carried out in collaboration with US palaeontologists. "It is a small animal the size of a chicken or a crow that lived 95 million years ago," said researcher Sebastian Apesteguia. "Alnashetri measured approximately 60 to 70 centimetres long, including the tip of the tail, of which half of the body is tail. It probably weighed less than one kilo because first it was feathered and second, the bones are hollow because it is a carnivorous dinosaur, they are theropods, so it weighed nothing," he persisted. Apesteguia added that the animal fed on small mammals or reptiles and had 'well-developed arms', which is uncommon in its species. The palaeontologist reported that, as part of the discovery, they found different specimens in the Kokorkom desert in the Argentine Patagonia, including "snakes with legs, many terrestrial crocodiles of the same species and also many carnivores of the same species." Finding this fossil 'exceptionally well preserved and complete' allows them to "rewrite the history of alvarezsaurians, an 'enigmatic group of small carnivorous dinosaurs,'" as CONICET detailed in a statement.
