It probably had a large horn on its forehead, but fossils of the horn have not been found. The teeth were tall-crowned and were covered with cement and wrinkled enamel. Its mouth at the front was a beak; there are no teeth in front of the molars.
The specimens of E. sibiricum are up to 4.5 m (15 ft) in body length with shoulder heights over 2 m (6 ft 7 in). E. caucasicum was at least 5 m (16 ft) in body length with an estimated mass of 3.6–4.5 tonnes (4–5 short tons). This is based on isolated molars which are larger than those of the Siberian species.
Both species were among the largest in the family Rhinocerotidae, comparable in size to the woolly mammoth and larger than the woolly rhinoceros. The feet were unguligrade, the front larger than the rear, with 4 digits at the front and 3 at the rear.
