Sauropod Dinosaurs

TL;DR

Largest terrestrial animals ever (50-80 tons), approaching fundamental structural limits.

Reptile (extinct)

Largest terrestrial animals ever (50-80 tons), approaching fundamental structural limits. Required semi-aquatic lifestyles or quadrupedal postures to distribute weight across four pillar-like limbs. Bone material has finite compressive strength (~200 MPa for cortical bone) - beyond certain sizes, no amount of thickening prevents failure.
