The Pinta Island tortoise[4] (Chelonoidis niger abingdonii[2][5]), also known as the Pinta giant tortoise,[2]Abingdon Island tortoise,[1] or Abingdon Island giant tortoise,[2] is a recently extinct subspecies of Galápagos tortoise native to Ecuador's Pinta Island.[1]
The subspecies was described by Albert Günther in 1877 after specimens arrived in London. By the end of the 19th century, most of the Pinta Island tortoises had been wiped out due to hunting.[6] By the mid-20th century, the subspecies was assumed to be extinct[7] until a single male was discovered on the island in 1971. Efforts were made to mate the male, named Lonesome George, with other subspecies, but no viable eggs resulted. Lonesome George died on 24 June 2012, and the subspecies was believed to have become extinct with his death.[8] However, 17 first-generation hybrids were reported in 2012 from Wolf Volcano on Isabela Island during a trip by Yale University researchers. As these specimens were juveniles, their parents might still be alive.[9][10] The subspecies is classified as extinct on the IUCN Red List.[1]
