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 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.21
Oraindik eztabaidagai
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
