Procoptodon

*Procoptodon goliah* was the largest kangaroo ever to have lived, standing up to 2 metres (over 6 feet) tall. It was incredibly massive, weighing around 230 kilograms (over 500 pounds). It was significantly larger and heavier than any modern red or grey kangaroo.

The giant *Procoptodon* became extinct in Australia around 46,000 years ago. This extinction occurred during the Late Pleistocene epoch. Scientists believe that environmental changes and the arrival of early humans likely contributed to their disappearance.

Unlike modern kangaroos, *Procoptodon* had a distinctly short, flat face and unusually long arms. It also possessed a single, very large claw on each of its front feet. Its massive size and unique limb structure suggest it was adapted for browsing on tall shrubs and trees.

*Procoptodon* lived in ancient Australia, where its fossil remains have been found in various locations, including South Australia and New South Wales. It inhabited regions of open woodland and forest edges. These environments provided the leaves and vegetation it needed to sustain its massive size.
