The Los Angeles Times reports that Zoo officials say Nola, 41, was euthanized early Sunday, Nov. 22, 2015 as she was suffering from a number of old-age ailments, including arthritis, and had also been treated for a recurring abscess on her hip. The rhino had been a draw at the Safari Park since 1986.(AP Photo/Lenny Ignelzi, File)
