Hundreds of ancient earthworks resembling those at Stonehenge were built in the Amazon rainforest, scientists have discovered after flying drones over the area.

The findings prove for the first time that prehistoric settlers in Brazil cleared large wooded areas to create huge enclosures meaning that the 'pristine' rainforest celebrated by ecologists is actually relatively new.

OK, they're round, but other than that, I don't see any similarity to henges.
