The illustration portrays a reconstruction of Genyornis newtoni at the water’s edge in a wetland or swamp-like environment. The scene itself was inspired by locations that exist in southern South Australia today, such as Ngarrindjeri country in and around the Coorong and lower Murray River. However, back when Genyornis newtoni was kicking about, this type of environment would have been more widespread across the country. Many Genyornis fossils are recovered from Lake Callabonna which is more than a day’s drive north of there and is a dry salt lake nowadays. Back in the day this would have been much wetter place.

Felidae, a highly diverse carnivoran family, emerged during the Oligocene in Eurasia and quickly spread worldwide during the Miocene. Although Felidae represents the sole extant cat-like clade, the sabertoothed morphotype is a textbook example of iterative evolution, having evolved many times among placentals, marsupials, and gorgonopsians. Nimravidae is a well-diversified yet fully extinct carnivoran clade that extensively explored a range of cat-like morphologies, and although they have been commonly called ‘false cats’ or ‘false sabertooth cats’ in opposition to the ‘true cats,’ they evolved cat-like morphologies, including both saber-toothed and non-saber-toothed forms, tens of millions of years prior to the appearance of felids.
