Islands tend to be uniquely susceptable to human extinctions, due to small habitat sizes, and limited natural predators. Given an extinction date and hint, list each animal formerly associated with islands
This includes species that were previously found on a mainland and survived in an island refuuge

Kaua'i O'o
The last induvidual, Lonesome George, lived for 40 years after scientists were unable to find any other living members of the species.
Tried to select for the most "interesting" island animals that died out during the last 10,000 years, regardless of how well known they are. The fauna of New Caledonia and Melanesia as a whole is fairly obscure despite having interesting things like fully terrestrial crocodiles and wannabe-ankylosaur land turtles. That said, well known island fauna like Dodos, a particularly famous species of galapagos giant tortoise get a spot.
Generally tried to avoid animals where the extinction date is unclear, or might still exist. The only exceptions for this is: 1. the Thylacine, which is unusual enough to really deserve a spot here. Personally I think the chances of it still existing are pretty low, I consider most sightings to be similar to bigfoot or Loch Ness Monster sightings, more a cultural meme than real animals. 2. the Pinta Island Tortoise, which still exists in hybrids even if purebred members of the species died with Lonesome George. In that case I decided that hybrids do not count
