The appearance of woolly rhinos is known from mummified individuals from Siberia as well as cave paintings.[1] An adult woolly rhinoceros was typically around 3 to 3.8 metres (9.8 to 12.5 ft) in length, with an estimated weight of around 1,800–2,700 kg (4,000–6,000 lb)[2] or 2,000 kg (4,400 lb).[5] The woolly rhinoceros could grow to be 2 m (6.6 ft) tall;[2] the body size was thus comparable to, or slightly larger than, the extant white rhinoceros.[4] Two horns on the skull were made of keratin, the anterior horn being 61 cm (24 in) in length,[5] with a smaller horn between its eyes.[6] It had thick, long fur, small ears, short, thick legs, and a stocky body.
