Aëtosauria Mainly Triassic group of primitive thecodontian (‘tooth-in-socket’) reptiles (see THECODONTIA). They resembled heavily armoured crocodiles, and appear to have been specialized herbivores or possibly omnivores. They grew up to 3 m long, and their armour plating comprised rows of bony plates.
