Conservation Status

Extinct

Last Record: 24 June 2012

IUCN status: Extinct in the Wild

 

Chelonoidis abingdonii was believed to be extinct, before a single individual was found (Vagvolgyi, 1974). "Lonesome George" as he became known, was therefore without a conspecific companion (male or female), until his death on 24 June 2012. He was living at the Charles Darwin Research Station on the Galápagos Islands.

However, some slight hope remains of finding other purebred tortoises of his sub-species given the discovery of at least one first-generation hybrid between George's sub-species and one of the Isabela Island sub-species several years before his death.

Rumours existed that another male, nicknamed "Tony", who currently resides at the Prague Zoo, was a purebred Abingdon Island Tortoise. However, nothing seems to have been done about this, and no DNA tests were performed to anybody's knowledge, to either confirm or refute this claim. And given the immense importance of the potential discovery, the inaction of zoo staff is very suspicious. It was therefore most likely a publicity stunt by the offending zoo to attract more visitors.
