17 Animals That Became Extinct In Our Lifetime
1. Pinta Island Tortoise, June 24, 2012
The last of his kind, Lonesome George died this weekend in his pen at a research facility. His exact age isn't known, but he was estimated to be over 100.
2. Baiji or Yangtze River Dolphin, 2006
Declared extinct in 2006, a video of what appeared to be a baiji dolphin was taken in 2007. The species is still considered "functionally extinct", meaning that if there is only one of a few old creatures alive, no new ones will be born.
3. Western Black Rhinoceros, 2011
A subspecies of the black rhino that lived mainly in Cameroon, the western black rhino was a victim of rampant poaching, even after protections were issued in the 1930s. Scientists searched for any signs in 2006 and came up empty, and it was offically declared extinct in 2011. The other 3 remaining subspecies of black rhinos are also critically endangered.
