Ecology
Ankylosauruses graze in herds across temperate grasslands and floodplains, browsing on tough vegetation that softer beasts ignore. Their thick armor plating and bony tail-club deter all but the largest predators, and adult bulls have been known to break charging tyrannosaurs' jaws with a single swing. They drink at riverbanks, follow seasonal migrations, and bury their dead in clay mud, where calcified shells preserve fossils for millennia. They share territory with triceratops without conflict.
Behaviour
Ankylosauruses are placid grazers but defend themselves and their calves with terrifying force. They walk slowly, deliberately, never panicked, and turn their armored sides toward threats. Their tail swing is precise; they aim deliberately, not blindly. When wounded, they hunker down rather than flee, presenting impenetrable plates. Bulls during rutting season clash tail-clubs with rivals in dramatic, ritualized fights that rarely kill but leave lasting scars on shells.
Origin
Ankylosauruses survive in pockets of timeless lands like the Isle of Dread, lost plateaus, and primal feywilds where time bends backward. Some scholars believe they emerged from the Beastlands, brought to the Material Plane by druidic ritual or planar incursion. Others argue they are simply ancient beasts the world forgot, hidden in places where progress never reached. Their presence in adventure regions often signals primal magic or temporal disturbance.
