Arctodus simus v Toxodon platensis
Arctodus simus
Arctodus (Greek, "bear tooth") — known as the short-faced bear or bulldog bear — is an extinct genus of bear endemic to North America during the Pleistocene ~3.0 Ma.—11,000 years ago, existing for approximately three million years. Arctodus simus may have once been Earth's largest mammalian, terrestrial carnivore. It was the most common of early North American bears, being most abundant in California. It was native to prehistoric North America from about 800,000 years ago, and became extinct about 12,500 years ago. It has been found from as far north as Ikpikpuk River, Alaska to Lowndes County, Mississippi. It is one of the largest bears in the fossil record and was among the largest mammalian land predators of all time. The type specimen came from Potter Creek Cave in Shasta County, California. In a recent study, the mass of six A. simus specimens was estimated, one-third of them weighed about 900 kg (1 short ton), the largest being UVP 015 at 957 kg (2,110 lb), suggesting specimens that big were probably more common than previously thought.

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.

Thank you Taipan. In this video below, the toxodon can charge like a rhino and wallow in water like a hippo. This video invoves a bit of sci fi about a man named Nigel going to the past to get extinct animals back to his time. The film is from Animal Planet called prehistoric park - documentary that involves a bit of sci fi:

sorry that is the only vidoe of Toxodon i can find at the moment.

Edit: found another one, smilodon takes down Toxodon:

The toxodon lacks the horns of a rhino and the wipe gape of a hippo yet the artodus simus lacks the grappling ability of big cats and other bears.
