Campestribrotherium is the largest land mammal on earth, even bigger than the ancient Indrocotherium (its ancestors), weighing about 25 tons and is about 26 feet tall at shoulder height and is about 35 feet long from nose tip to tail tip.

Biology
Campestribrotherium is much bigger than its ancestors, the Indricotherium, and even larger than the true world's largest land mammal, the Palaeoloxodon (which is basically just an elephant). This animal is a gigantic giraffe-like rhino that prefers to browse on leaves and berries. Their calves can weigh about 3 tons and reach about the size of a sub-adult Sumatran elephant. When they reach about the size of a large stegodon, they have no natural predators.

Evolution
In the Late Holocene, humans mastered time travel and had brought back many recent extinct animals and prehistoric animals from extinction, with Indricotheres being one of these "resurrected" animals. After most humans left earth, many formerly extinct species (including prehistoric species) like Indricotheres had escaped from cenozoic parks. They had adapted to deal with competition from elephants, prosauropods, sauropods, and many other large species.
