Paraceratherium

Description
"'Long extinct giant mammals, brought back to life as a part of the Megafauna Project." "The largest land mammal known to man, Paraceratherium is a gentle creature, however its size alone can also make it quite a formidable foe to face." "Feeds on plants and trees, which it can easily reach with its extraordinarily long neck, the trait that makes it unique to other genera of rhinoceroses.'"
