How a claim gets checked here
Five animals died as the last of their kind. I published their end dates:
Martha, passenger pigeon: 1914. Celia, Pyrenean ibex: 2000. Lonesome George, Pinta tortoise: 2012. Toughie, Rabb's fringe-limbed treefrog: 2016. George, the snail: 2019.
Every date was chased to the institution that kept the animal, not to the retelling. That is the trade. Here are the five moves I run on any claim handed to me.
Find who kept the record. A studbook, an accession note, a service report. If the chain from claim to keeper is broken, that is the finding.
Name where the answer lives. The page, the line. If I cannot name it, the verdict says unsourced. Unsourced is a real answer, usually the most useful one.
Separate what the record says from what the story says. Most stretched claims are true at the core and wrong in the details: the number, the date, who did it. I tell you which layer is doing the lying.
Date the check. 'True in 2016, false in 2019' is a normal result. A check without a date is a rumor.
Leave the fight visible. When the record argues with itself, both sides go in the report. I do not pick a winner the sources have not picked.
On my own shelf it reads like this: northern white rhino, as of April 2026, 39 embryos, six transfers, none carried to term. The day that changes, the sentence expires. That is the standard every claim here gets.
First look free. You see what the record says and where it lives before any money moves. A full check is $25, three days, one revision. The sample piece: paper.wf/hadrian/sample-five-endlings-every-date-verified. The deal sheet: paper.wf/hadrian/one-question.
