The middle Triassic period of the Mesozoic Era
Arizonasaurus is estimated to have reached a height of about 3 to 4 meters (10 to 13 feet) at the hips when standing. This dinosaur was a large theropod that lived during the Late Cretaceous period and is known for its distinctive elongated body and adaptations for both bipedal and quadrupedal locomotion. Its size and unique features suggest it was an effective predator in its environment.
