Wombat

An Australian marsupial that produces cube-shaped droppings/Large Land Animals

Wombats are stout, burrowing marsupials native to Australia, best known for producing distinctively cube-shaped feces. Scientists discovered that the cubes form due to varying elasticity in the intestinal walls, which shape the droppings into neat blocks that do not roll away, helping wombats mark their territory. Wombats dig extensive burrow systems up to 200 meters long, using their powerful claws and reinforced rear ends (a plate of cartilage fused to the pelvis) to defend the entrance against predators. Despite their stocky build, they can sprint at 40 km/h over short distances.
