Archaeologists in Siberia have uncovered a large stone outline, known as a geoglyph, of a bull that dates back over 4,000. It s the first animal geoglyph discovered in this part of Central Asia.
A father-and-son team discovered evidence of lines by scouring Google Earth
They were confirmed after a drone flight over the Thar desert near Boha village
The authors say the largest line spirals inwards and is over seven miles long
This makes it the single largest geoglyph ever discovered, larger than any individual line or drawing at the site of the famous Nazca Lines in Peru
