Australian researchers have identified two new mammals in the Land Down Under — both cousins of the doe-eyed flying marsupials known as greater gliders, according to a report.

A study published in Nature’s Scientific Reports journal found two new distinct and smaller species of gliders in northern and central Australia, outside of the marsupial’s known habitat in the country’s southern end, the Sydney Morning Herald reported.

“Australia’s biodiversity just got a lot richer,” Andrew Krockenberger, a professor at James Cook University and a co-author of the study, told the outlet. “It’s not every day that new mammals are confirmed, let alone two new mammals.”
