The Patagonian forest in Southern Chile might be home to the world's oldest tree after a new study found that an ancient alerce tree known as "great grandfather" could be more than 5,000 years old.

Scientists were not able to determine an exact age based on tree rings because of the tree's massive trunk. Normally, a 1 meter (1.09 yards) cylinder of wood is extracted to count tree rings, but the great grandfather's trunk has a diameter of 4 meters!
