The Dinosauria (ディノザウリア, Dinozauria?) is the Heavy Tank Type Legion unit. It greatly outclasses the other standard Legion types, such as the Ameise, Grauwolf, and Löwe. This unit was once used as the host of Shourei Nouzen, which was later destroyed by the Spearhead Squadron.
As one the heaviest class of the standard Legion types, the Dinosauria weighs 100 tons and is able to easily trample and crush its adversaries. It's large 155 mm cannon allows for superior fire power compared to the Löwe, and both its 75 mm coaxial cannon and the twin 12.7 mm machine guns allow it to pick off smaller, lightly armored targets such as the M1A4 Juggernaut. It is heavily armoured all around and even the top of the turret is impenetrable by the 57mm cannon on the Juggernaut. The only weak spot on the vehicle is the engine vent on the back end of the hull. The specific Dinosauria manned by the vestiges of Rei was able to use Liquid Micromachine "arms" to perform various tasks.
