Lonesome George was the last specimen of giant Galapagos tortoises from Pinta Island. Biologists tried to find a mate for him, but sadly, none were to be found. He died, the last of his species, in 2012 at a roughly estimated age of 100 years.
The American Museum of Natural History decided to have him preserved for display. They clearly have the taxidermic expertise required, as you can see if you've ever visited their dioramas. The biggest dilemma was to choose the proper pose for this iconic creature.
