Orkoraptor, scientifically known as "Orkoraptor burkei," is a theropod dinosaur that belonged to the Megaraptoridae family. It lived around 95 million years ago during the Late Cretaceous period. The name "Orkoraptor" combines "Orko," a reference to the mountain god in Andean mythology, with "raptor," derived from Latin, meaning "thief" or "plunderer."

The discovery of Orkoraptor occurred in 2008 in the Neuquén Province of Patagonia, Argentina. The fossil remains provided a unique opportunity for paleontologists to understand the ancient predators that once roamed this region.

As a Megaraptor dinosaur, Orkoraptor possessed several characteristics typical of its group. It was a bipedal predator with sharp, serrated teeth and powerful claws on its forelimbs, indicating its carnivorous nature. Its relatively large eyes and keen sense of smell were likely adaptations to locate and capture its prey.

Orkoraptor's size was comparable to a medium-sized theropod, reaching approximately 20 feet (6 meters) in length and weighed about 500 kg or 1100 lbs. Although not as massive like Tyrannosaurus rex, Orkoraptor was no less formidable as a predator, and was likely alot more agile in its movements than the larger theropods.
