Two tiny marsupials once written off as extinct for around 6,000 or even 7,000 years have been found alive in dense rainforest, turning a remote corner of New Guinea into a global conservation focal point. Their rediscovery validates long held knowledge among Papuan communities and challenges assumptions about how thoroughly science has mapped the region’s biodiversity. Together, these “Lazarus” mammals show how intact forests can hide species that vanished from the fossil record millennia ago.
Pygmy long-fingered possum
The pygmy long-fingered possum was known only from ancient remains until field teams reached the Vogelkop region of Indonesian Papua, part of the wider New Guinea highlands. Researchers working with local Papuan clans documented the tiny nocturnal animal after camera traps and nighttime searches in mossy forest, confirming that a species thought gone for about 6,000 years is still clinging on. Reporting on the find notes that conversations with villagers were key to locating the surviving population in steep, little surveyed terrain.
Details released by the Australian Museum describe the possum’s elongated middle finger, adapted for probing wood boring insect larvae, and its reliance on old growth trees in cool, wet forest. Coverage of the rediscovery in West Papua stresses that the animal had last been known from fossils dated to roughly 6,000 years ago. Scientists warn that logging roads and climate shifts could quickly erase this remnant group, turning a conservation success into a brief reprieve unless habitat protection follows.
Vogelkop ring-tailed glider
The Vogelkop ring-tailed glider was the second surprise, a small gliding marsupial that had also disappeared from the fossil record for around 6,000 years. Biologists surveying forest on the Vogelkop Peninsula of Western New Guinea used spotlighting to confirm living animals, then linked the sightings to stories that Two local communities had shared about a “flying” tree dweller. Genetic work and measurements are now being used to compare the glider with museum specimens and subfossil bones collected decades earlier.
Reports on the expedition describe how the glider’s broad membranes allow it to cross gaps between emergent trees while feeding on sap and insects, a lifestyle that depends on continuous canopy. One account of the rainforest survey explains that the animals were found in Indonesian Papua after a targeted search for species believed extinct for 6,000 years, part of a project that invited scientists to Learn from Indigenous knowledge. A related announcement described how The Bishop Museum in Written collaboration highlighted the glider and possum as “Two Marsupials Thought Extinct for” 7,000 “Years Found Alive” in “New Guinea,” underscoring how fragile rainforest corridors hold species that global science almost missed.
