New Nazca Lines were exposed by recent sandstorms in the Peruvian region of Ica.
The pilot Eduardo Herrán Gómez de la Torre discovered a huge geoglyph of what appears to be a 196ft-long snake, as well as a llama, above an unidentified bird.
These new lines join existing geoglyphs of a dog, hummingbird, condor and a monkey, thought to have been drawn by the ancient Nazca people between the first and sixth centuries.
The geoglyphs, more commonly known as the Nazca Lines, were first spotted from the air in 1939 when a pilot flew over the Nazca region of the Peruvian coastal highlands.
They were designated as a UNESCO World Heritage Site in 1994, and the area stretches more than 50 miles (80km) between the towns of Nazca and Palpa, 248 miles (400km) south of Lima.
The mystery about why they were created has been debated for decades.
One theory is that the geoglyphs are connected in some way to water.
For example, a triangular geoglyph at the bottom of the Cerro Blanco mountain runs along the water veins inside the mountain, while the condor geoglyph is linked to local legend, which states that when the condor flies over the mountain, ‘great rains follow’.
Similarly, the ‘hummingbird’ geoglyph only appears in the summer following heavy rainfall.
All of the drawings were said to have been drawn using a single line, that never crosses itself, and were believed to be an appeal to the gods to bring rain.
