One of the world's oldest gorillas has died at San Diego Zoo Safari Park. The park says Vila, who turned 60 in October, died Thursday surrounded by members of her family troop. Authorities say she was the matriarch of five generations of gorillas and during her life served as a surrogate mother for several western lowland gorillas. Vila had arthritis and other health conditions related to her age and had been under veterinary care. She came to the zoo in 1959 and was moved to Safari Park in 1975.
