(WVLT/Gray News) - Dolly, the oldest rhinoceros in the United States, has died at the age of 56 ... Dolly, a southern white rhino, was born in 1968 at the Hluhluwe-Imfolozi Park in South Africa.

Archie, a 55-year-old southern white rhino at the Jacksonville Zoo and Gardens, has died. He was the oldest male of his species in human care and a founder of the North American rhino population.

Zoo officials said 55-year-old Archie had recently been diagnosed with a soft tissue sarcoma. Due to his age and the extent of the tumor, extensive treatment would have been too taxing for him.
