The largest land animal ever at 77 tons and 37 meters long. Despite this massive size, Patagotitan moved slowly, supported by columnar limbs and a skeletal system optimized to distribute weight while minimizing bone mass.
Critically, sauropods had pneumatic (air-filled) bones, reducing structural mass - an adaptation that allowed them to approach the theoretical 80-ton terrestrial maximum. This represents the absolute limit for land animals; physics doesn't negotiate.
