Polar Bear v Toxodon platensis
Polar Bear - Ursus maritimus
The polar bear (Ursus maritimus), a bear native to the Arctic, is the apex predator within its range. Its thick blubber and fur insulate it against the cold. Its fur is hollow and translucent but usually appears as white or cream coloured, thus providing the animal with effective camouflage. Its skin is actually black in color, however. The bear has a short tail and small ears that help reduce heat loss, as well as a relatively small head and long, tapered body to streamline it for swimming. The polar bear is a semi-aquatic marine mammal that depends mainly upon the pack ice and the marine food web for survival. It has adapted for life on a combination of land, sea, and ice. Scientists and climatologists believe that the projected decreases in the polar sea ice due to global warming will have a significant negative impact on of this species within this century. The polar bear (Ursus maritimus) is the largest species of all bears and is the largest terrestrial carnivore on earth. Fully grown male polar bears range from 7' to 11' when standing upright, and weigh from 660 to 1,320 pounds. Females stand from 6' to 8' and weigh anywhere from 400 to 700 pounds. The largest polar bear on record was over 12' and weighed 2,210 pounds.

Toxodon platensis
Toxodon is an extinct mammal of the late Pliocene and Pleistocene epochs about 2.6 million to 16,500 years ago. It was indigenous to South America, and was probably the most common large-hoofed mammal in South America at the time of its existence. Toxodon was about 2.7 m (8 ft 10 in) in body length, with an estimated weight up to 1,415 kg (3,120 lb) and about 1.5 m (4 ft 11 in) high at the shoulder and resembled a heavy rhinoceros, with a short and vaguely hippopotamus-like head. Because of the position of its nasal openings, it is believed that Toxodon had a well-developed snout. It had a massive skeleton, which suggests that it supported a large muscular body. It had short stout legs with three functional toes, with most of the body weight being borne by the central toe.

A big polar bear can probably pull down a toxodon. The toxodon however outweighs most yallowish white bears by a decent size advantage. The toxodon also has some sharp teeth of its own though it bite might not be as efficient as the slicing bite of a polar bear.

Anymore comments, the toxodon is definitely too large for even an exceptionally big black bear and some brown bear subspecies.
