Brontotherium (misspelled as Brontoteriy in Carnivores Ice Age) is a large, rhinoceros-like herbivore with a massive double-horn.
Carnivores Ice Age
In Carnivores Ice Age, the Brontotherium is the first and cheapest animal available to hunt, and is the second largest herbivore in the game. However, in the game, the animal is covered in fur, when in real life Brontotherium was probably covered in a hard, rhinoceros-like skin. Although it is classified as not dangerous in-game, it can still kill the player by trampling him with its massive forelegs. This also occurs with the giant deer. It is possible to be confused with the Woolly Rhinoceros from a distance, but this is unlikely due to differences in size and shape.
