Pleistocene

Fossilized feces from ancient ground squirrels contained remains of mammoths, bison, and big cats. These findings include some of the oldest DNA ever reconstructed, suggesting the squirrels scavenged carcasses during the Pleistocene era.

A fossil skull fragment discovered in a museum's unsorted collection revealed the existence of the Owen’s giant echidna, Megalibgwilia owenii, which once lived in Victoria during the Pleistocene epoch. This species, twice the size of modern echidnas, weighed up to 15kg and measured about 1 metre in length.
