Turtles, Tortoises and Terrapins

The most recent tortoise extinction happened on 24 June 2012 when the only surviving specimen of the Abingdon Island Giant Tortoise (or Pinta Island Giant Tortoise), a species of Galápagos Giant Tortoise, died in captivity. The scientific name of this species is: Chelonoidis abingdoni. This Abingdon Island Giant Tortoise was the very last of his kind and was named Lonesome George (or Solitario Jorge in Spanish). George was living at the Charles Darwin Research Station on Santa Cruz.

Reptiles have suffered (and still do) from destruction of their habitat, hunting and the introduction of cats, dogs and mongooses on their islands by humans. The subjoined table shows the turtle, tortoise and terrapin species and subspecies that recently became globally extinct.
