Last of his kind: Lonesome George, a 100-year old giant Pinta Island tortoise, passed away on June 24, 2012. George was the last known individual of his subspecies, Geochelone abingdoni, also called the Pinta Island tortoise or Abingdon Island tortoise.
The subspecies represented by George was thought to be extinct already. Then in 1971, George was found. George was taken in captivity and placed with females of a closely-related subspecies, but George did not show any interest. He earned his lonesome nickname while living at the Charles Darwin Research Station on Santa Cruz Island, part of Galápagos National Park.
