A group of archaeologists working in the Amazon rainforest have discovered a number of geometric carvings in the soil which are thought to be some 700 years old.
The carvings - also called geoglyphs - were found by a team of researchers after an area of the rainforest was cleared, but many more have been found using satellite imaging such as the technology used by Google Earth to allow people to look at the planet from above.The Amazon rainforest is the largest rainforest on earth - in the basin of the Amazon river - which is an area which covers land 48 times the size of the US.
Figures on Monga Bay suggest that between 2000 and 2005, more than 132,000 square kilometres of the Amazon rainforest was cleared due to the industry in the area.
Large areas of land are cleared for use by logging firms as well as farms used by the international meat industry.
