The species range contracted towards Siberia beginning around 17,000 years ago, with the youngest known records being around 14,000 years old in northeast Siberia, coinciding with the Bølling–Allerød warming, which likely disrupted its habitat. Mummified carcasses preserved in permafrost and many bone remains of woolly rhinoceroses have been found. Images of woolly rhinoceroses are found among cave paintings in Europe and Asia. The woolly rhinoceros was covered with long, thick hair that allowed it to survive in the extremely cold, harsh mammoth steppe. It had a massive hump reaching from its shoulder and fed mainly on herbaceous plants that grew in the steppe. The woolly rhinoceros was a member of the Pleistocene megafauna. A century of conservation efforts followed, and there are now an estimated 20,000 individuals in the wild today.The woolly rhinoceros ( Coelodonta antiquitatis) is an extinct species of rhinoceros that inhabited northern Eurasia during the Pleistocene epoch. Considered extinct for much of the late 19th century, a small population was discovered in southern Africa in 1895. The southern white rhino, however, is considered a conservation success story. The northern subspecies of white rhino only has two individuals remaining today, making their population functionally extinct. In zoological settings, southern white rhinos usually eat grass hay, hay pellets and pelleted grain formulated for herbivores. Because of this ability, white rhinos are pure grazers in the wild. These flat lips allow the rhinos to get low to the ground and consume the grasses with ease. These are integral parts of their feeding adaptations, since they enable the animals to graze on short grasses. White rhinos are known for their flat, wide upper lips. Southern white rhinos are found in grassland savanna areas in middle Africa and more prevalently in southern Africa. The southern white rhino is the most numerous of all the rhinos, with a majority of the population focused in South Africa. The northern white rhino is now the rarest of all rhinos, with only two female individuals remaining in Ol Pejeta Conservancy in Kenya. There are two geographically separated subspecies of white rhino: the northern white rhino and the southern white rhino. Look for Mumbles or Kiazi in the newly renovated outdoor habitat, or in the indoor area of our rhino complex, just around the corner from the outdoor habitat. Females usually begin to breed at 6 years old males, at 10 to 12 years old. The usual interval between births is two to three years. Rhinos give birth to a single calf, and calves are usually weaned when they are 1 to 2 years old. Actual fights are rare, however, and confrontations usually consist of horn-butting, false charges and other displays.īreeding occurs year-round, with courtship and mating periods lasting one to three weeks. While dominant males will tolerate females and sub-adult males in their territory, invading bulls will be challenged. Territories are often marked by spraying urine, spreading dung, foot-dragging and horn-scraping. Dominant males are typically solitary and occupy smaller ranges than females do. Larger, temporary groups of 14 or more individuals are often seen, usually made up of immature individuals or mothers without calves. Offspring usually stay with their mothers until the next calf is born. White rhinos are considered the most social of all the rhinos. The front horn is longer and averages 35 inches in length, but may grow as long as 60 inches. Both black and white rhinos have two horns. White rhinos can also be distinguished from black rhinos by their longer skulls, less sharply-defined foreheads, and more pronounced shoulder humps. White rhinos use their broad, square upper lips to graze on savanna grasses, while black rhinos use their pointed upper lips to browse on leaves from trees and shrubs. The “white” aspect of the name comes from an Afrikaans word meaning “wide.” White rhinos are distinguished from black rhinos by their size and by the shape of their upper lip. The southern white rhino is among the most recognizable of all of Africa’s large mammals, standing up to 6 feet tall at the shoulder and weighing up to 6,000 pounds. White rhinos are the largest of the rhinos. White rhinos are one of five species of rhinoceros southern white rhinos are one of two white rhino subspecies and are native to middle and South Africa.
