Six thousand years ago — before the Egyptian pyramids were built — two small, extraordinary marsupials vanished from the fossil record. For six millennia, they existed only as bones and memory. And then, in the ancient rainforests of West Papua, researchers found them alive.
The announcement, made in March 2026, describes one of the most remarkable wildlife rediscoveries in modern natural history. Two marsupial species — the pygmy long-fingered possum (Dactylonax kambuayai) and the ring-tailed glider (Tous ayamaruensis) — once believed to have been lost to extinction thousands of years ago, are living in the dense, remote forests of the Vogelkop Peninsula in West Papua, Indonesia.
The Animals Themselves
The pygmy long-fingered possum is unlike most things you have ever seen. It is a striped marsupial, small enough to sit in your palm, and it has one extraordinarily elongated finger on each hand — a natural tool it uses to prize insect larvae from beneath the bark of trees. It looks like it was designed for a rainforest that had time to perfect every adaptation over millions of years.
The ring-tailed glider is a relative of Australia's greater gliders, a tree-dwelling possum with large dark eyes, a prehensile tail, and membranes stretching from limb to limb that allow it to glide silently through the forest canopy. It is considered sacred by some Indigenous groups in the region — a detail that may have quietly protected it for longer than any conservation programme could.
How They Were Found
The research was led by Professor Tim Flannery of the Australian Museum — one of the world's most respected mammalogists. But the discovery was not made in a laboratory or from a satellite image. It was made possible by the Indigenous knowledge of the Tambrauw and Maybrat clans, whose elders knew these animals and guided the researchers to where they could be found.
The evidence was pieced together from multiple sources: a previously misidentified museum specimen collected in 1992 at the Australian Museum, rare photographs taken by local researchers, fossil fragments from collections around the world, and the oral knowledge of communities who had lived alongside these animals when everyone else thought they were gone.
Scientists call species like these Lazarus taxa — named after the biblical figure raised from the dead. They reappear in the living world after being recorded only in fossils. Most such cases involve marine invertebrates or ancient fish. Finding two warm-blooded, tree-dwelling marsupials is extraordinary at any time.
What It Means
The Vogelkop Peninsula of New Guinea has long been considered one of the most important and least-explored bioregions on Earth. It is home to species found nowhere else, and much of it remains beyond the reach of roads. That remoteness, combined with the respect of local communities for the land and its creatures, may be exactly what kept these animals alive while the rest of the world wrote them off.
Six thousand years of absence. Found in a forest. Still here, quietly going about the business of being alive.
