Here's a page that can explain more eloquently than I: www.orcawatcher.com/2011/07/j2…
Excerpt: "One interesting thing Ken explained was how they arrived at 1911 as the estimated birth year for Granny... I guess they had photos of both J1 Ruffles and J2 Granny in 1971 and both were already full grown adults. Since orcas reach full size around the age of 20, they made the estimated birth year for J1 Ruffles as 1951 (1971 - 20 years). Due to the way Granny and Ruffles associated with one another, they suspected that she might be Ruffles' mother. Since Granny was never seen with a new calf since the study began, they assumed she was post-reproductive, and that perhaps Ruffles was her last calf. Females generally stop reproducing around the age of 40, so if she had Ruffles when she was 40, her birth year would be about 1911 (1951 - 40 years)."
