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.
Nazca Lines
The unusual formation of white lines that can be seen and appreciated only from the sky remains one of the world’s biggest enigmas. The purpose of trapezoid elements, strange symbols, plant structures, pictures of birds and unrecognizable beasts etched on a giant scale is still unknown. Scientists estimated that the lines were created by Nazca Indians between 500 B.C and 700 A.D. meaning that these ancient drawings remain intact for more than 2500 years. The fans of conspiracy theories believe that the lines in the Nazca desert were created as an enormous airfield for aliens.
