吃：肉肉食恐龍白堊紀晚期

Noasaurus was a small, speedy meat-eater that lived in Argentina near the end of the Age of Dinosaurs. It had a strongly curved claw on each hand that it may have used like a hook to catch fish or other small animals. Noasaurus was about as long as a bicycle and probably hunted in the warm forests of South America.1

Noasaurus was named after the region where it was found: NOA stands for 'Noroeste Argentino', which means northwestern Argentina in Spanish.1

The only known skeleton of Noasaurus was discovered in 1975 by a team led by famous Argentine paleontologist José Fernando Bonaparte.2

Noasaurus lived about 71 to 69 million years ago, during the Maastrichtian stage of the Late Cretaceous.1

Its hand claw had a special V-shaped ridge and a triangular pit on the underside, which helped it grip prey.1

Noasaurus was a ceratosaur, a group of mostly meat-eating dinosaurs that lived mainly in the southern continents.2 1

It shared its home with the huge, armored titanosaur Saltasaurus and several kinds of primitive birds.1

The environment where Noasaurus lived was warm and humid, with tropical forests and many ferns and conifers.1

發現: Noasaurus was named by José Fernando Bonaparte and his student Jaime Powell in 1980. The fossils were found in 1975 at the El Brete site in Salta, Argentina, and included parts of the skull, spine, and a distinctive hand claw.2 1
仍有爭議: Scientists are not sure whether Noasaurus used its curved hand claws mainly for catching fish or for grabbing other small prey. Some studies suggest it was a piscivore (fish-eater), while others think it was a generalist carnivore.1
