It faced far forward, more than those of modern rhinos. The front horn reached at least 1 m long, up to 1.4 m, and its weight reached 15 kg. The molars were high-crowned and had a thick coat of cementum. It had 3 premolars and 3 molars in both jaws. Like other rhinos, adults did not have incisors. The teeth of the woolly rhinoceros had thickened enamel and an open internal cavity. This ossification inspired the junior synonym specific name tichorhinus, from Greek τειχος (teikhos) "wall", ῥις (ῥιν-) (rhis (rhin-)) "nose". Unique to this rhino, the nasal bones were fused to the premaxillae, which is not the case in older Coelodonta types or today's rhinoceroses. This adaptation probably evolved as a result of the heavy pressure on the horn and face when the rhinoceros grazed underneath the thick snow. The nasal septum of the woolly rhinoceros was ossified, unlike modern rhinos. Its massive lower jaw measured up to 60 cm long and 10 cm high. Strong muscles on its long occipital bone formed its neck hock and held the massive skull. It was longer than those of other rhinoceros, giving the head a deep, downward-facing slanting position, similar to its fossil relatives Stephanorhinus hemiotoechus and Elasmotherium as well as the white rhinoceros. Skull and dentition Woolly rhinoceros skull It also had thick skin, ranging from 5 to, heaviest on the chest and shoulders. Their tails were also relatively shorter. Its ears were no longer than 24 cm, while those of rhinos in hot climates are about 30 cm. The woolly rhinoceros had several features reducing the body's surface area and minimized heat loss.

The body's length ended with a 45 to tail with a brush of coarse hair at the end.Kalandadze N.N., Shapovalov A.V. Shorter hair covered the limbs, keeping snow from attaching. The hump also contained a fat reserve to aid survival through the desolate winters of the mammoth steppe.| last1=Kahlke | first1=Ralf-Dietrich | last2=Lacombat | first2=Frédéric }} Frozen specimens indicate that the rhino's long fur coat was reddish-brown, with a thick undercoat that lay under a layer of long, coarse guard hair thickest on the withers and neck. Its shoulder was raised with a powerful hump, used to support the animal's massive front horn. Compared to other rhinoceroses, the woolly rhinoceros had a longer head and body, and shorter legs. The two horns were made of keratin, with one long horn reaching forward, and a smaller horn between the eyes. ![]() A one-month-old calf was about 120 cm in length and 72 cm tall at the shoulder. It grew up to 2 m tall at the shoulder, about the same size as the white rhinoceros. An adult woolly rhinoceros typically measured 3 to from head to tail, with an estimated weight of around 1800 - or 2000 kg.
