Yes, they should probably all be casual if they were taken when he was in captivity (which they appear to be). There is one that is RG.
Interestingly, the default geoprivacy for Chelonoidis abingdonii is “obscured” even though the taxon is extinct and his location at the Charles Darwin Research Center was well-known and published in all kinds of media.
Makes sense to me. In the very unlikely case of one being observed in the wild, the observation would go to obscured immediately which I think is good. lonesome George us for sure a special case, but I get that you cannot accound for every weird twirk.
