Western Black Rhino Is Now Extinct

Coincidentally, we were just talking today in class about how extinction in general is a non-event in the geologic time scale, while mass-extinction is something different entirely.  Just saw this article about the Western Black Rhino's status changing to "extinct", as the last living animal was observed in 2006.

I'm not really sure how I feel about this "non-event."  Feels tragic to me...
