Pinta Island Tortoise

The Pinta Island tortoise (Chelonoidis abingdonii) was a saddle-backed giant tortoise endemic to Pinta, the northernmost major island of the Galápagos archipelago. Like the other Galápagos tortoise lineages it had diversified in isolation, evolving an upswept, saddle-shaped carapace that let it stretch its long neck toward the taller vegetation of an arid, low-lying island. For most of the twentieth century the form was assumed already gone, a casualty of two centuries of exploitation.

That assumption was overturned on 1 November 1971, when a single male was found on Pinta by Hungarian malacologist Jozsef Vagvolgyi, who had come to the island to collect snails. The animal was brought to the Charles Darwin Research Station on Santa Cruz Island and given the name Lonesome George. For four decades he was the most famous tortoise in the world and the singular, living face of extinction in progress.

Despite repeated, carefully managed attempts to breed George with females from the most closely related populations, no viable offspring were ever produced. He died on 24 June 2012, estimated to be a century or more old. With his death the lineage was considered extinct, and the IUCN Red List classifies Chelonoidis abingdonii as Extinct.

George’s case became a touchstone in conservation because it compressed the whole arc of an extinction into a single, watched lifetime. The drivers were almost entirely human and entirely reversible in principle, yet by the time the last individual was found, recovery of the lineage was already biologically out of reach.
