SAN FRANCISCO (AP) -- The San Francisco Zoo's beloved chimpanzee matriarch Tallulah is dead.
She died Sunday from heart disease related to breast cancer.
Tallulah, a fixture at the zoo for nearly a half-century, was believed to be in her mid to late 50s.
The Santa Cruz Sentinel (http://bit.ly/VPqTSN) says she came to the zoo in 1967 after being raised privately as a pet. Tallulah was among the nation's oldest chimpanzees in Association of Zoos and Aquariums-accredited zoos.
The primate was seen as the matriarch of the three other members of her chimpanzee troop.
