<br>My dictionary ("The Collaborative International Dictionary of English", apparently derived from Webster (1913)) defines "anecdote" as:<br> "A particular or detached incident or fact of an interesting nature; a biographical incident or fragment; a single passage of private life."
<br><br>Joao's problem is that the documentation is a collection of stories... who brought the tortoise to India, how long Lord Robert Clive kept him in his garden, etc. -- the more robust documentation is only from when the tortoise became a resident at the Calcutta zoo in 1875. But there is no good way of verifying that that tortoise was not obtained from the Seychelles in 1875 instead of much earlier (all of the people involved are now dead). So one may only have individual accounts (dairies, an occasional newspaper story, etc.) and so one may have significant difficulty confirming them.
<br><br>The somewhat less anecdotal tortoise longevity story involves a <font face="Arial, Helvetica, sans-serif">Madagascar
radiated tortoise (<i>Geochelone radiata</i>), known as "</font><font face="Arial, Helvetica, sans-serif">Tui Malila" which Captain James Cook presented to the </font><span class="dp_article">Tongan royal family in
</span><font face="Arial, Helvetica, sans-serif">1773 or 1777</font><span class="dp_article">. That tortoise was either 188 or
192 years old at its death in 1965.</span><br><br>Joao is one of the world's authorities in this area (documenting the maximum longevities of various species). If he could reasonably extend the longevity of a species I suspect that he would -- but one doesn't become an "authority" by making assertions that can easily be questioned.
<br><br>It will be interesting to see if efforts to date Addwaita using carbon dating will yield any useful information (I don't believe the carbon dating can be used with much certainty for periods of hundreds of years).
