Mount Owen Moa
In 1986, a group of archaeologists discovered an enormous, dinosaur-like claw when they were digging in a large cave system on Mount Owen in New Zealand. The claw was still intact with muscles and scaly skin attached to it. Later, the experts confirmed that it is a foot of now extinct wingless bird moa. The species disappeared about 2000 years ago. Moas were huge birds measuring up to 12 feet in height and up to 250 kg in weight. Unfortunately, they got hunted to extinction by our early ancestors.
