Deinotheriums are enormous pachyderms found in many differing habitats in a single region. A deinotherium herd consists of females, calves, and a skilled leader called a matriarch. Bulls usually stay on their own, especially during musth. In this time, the bulls go into a rage-like state, and are extremely dangerous. A bull in musth will attack anything in his territory.
Combat
A deinotherium uses its down-curved tusks in battle, as well as its large feet to smash down after rearing up.
Trample (Ex): As a full-round action, a deinotherium can move up to twice its speed and run over any opponents size Large or smaller. The deinotherium merely has to move over the opponents in its path; any creature whose space is completely covered by the deinotherium’s space is subject to the trample attack. If a target’s space is larger than 5 feet, it is only considered trampled if the deinotherium moves over all the squares it occupies. If the deinotherium moves over only some of a target’s space, the target can make an attack of opportunity against the deinotherium at a –4 penalty. A deinotherium that accidentally ends its movement in an illegal space returns to the last legal position it occupied, or the closest legal position, if there’s a legal position that’s closer. A trample attack deals bludgeoning damage (2d8+1-1/2 times its Str modifier). Trampled opponents can attempt attacks of opportunity, but these take a –4 penalty. If they do not make attacks of opportunity, trampled opponents can attempt Reflex saves to take half damage.The save DC against a deinotherium’s trample attack is 10+1/2 its HD + its Str modifier. A deinotherium can only deal trampling damage to each target once per round, no matter how many times its movement takes it over a target creature.

Pelorovis is a relative of the modern cape buffalo, but with much larger horns. They travel in large herds that roam the savannahs in search of food.
Combat
Pelorovis will usually make a mock charge in an attempt to scare off an opponent. If this doesn't work or the opponent retaliates, it will make a real charge, goring the opponent.
Powerful Charge (Ex): When pelorovis makes a charge, its attack deals extra damage in addition to the normal benefits and hazards of a charge.
