Researchers have reported finding living pygmy long-fingered possums and ring-tailed gliders in remote West Papua, species thought to have disappeared thousands of years ago. Their study, published in the Records of the Australian Museum, drew on fossils, photographs, museum specimens and knowledge shared by local communities; logging threatens the gliders’ forest habitat.
The pygmy long-fingered possum is a striped marsupial weighing about 200 grams. Researchers describe an unusual feature on each hand: its fourth finger is about twice as long as the other digits. The extended finger helps it extract wood-boring insect larvae, which the report identifies as its main food source. The species was understood to have vanished from Australia during the Ice Age.
The second animal, the ring-tailed glider, has a tail that can grasp branches and lives in hollows in tall trees. The study’s findings were assembled from decades-old fossils, rare photographs and museum specimens, followed by visits to remote locations in New Guinea. The supplied report does not give population estimates or detailed survey results.
Researchers worked with local elders from the Tambrauw and Maybrat communities. The report credits local knowledge with helping identify the animals. Rika Korain, a Maybrat woman and co-author, said that identification would not have been possible without that help. The scientists’ findings were published on Friday, March 6, 2026.
Why the Rediscoveries Matter
Living animals that were thought to have disappeared from the record are sometimes called “Lazarus taxa”. Finding two such species in one remote region adds evidence that New Guinea’s forests may still shelter animals poorly documented by science. It also shows the value of combining physical specimens and local knowledge when researchers investigate elusive wildlife.
The report also points to a direct conservation concern: logging is threatening the glider’s habitat, according to co-author Tim Flannery. Scientists and wildlife groups are seeking native title arrangements for forests, he said, which could require local consent before logging takes place. The article does not establish that those efforts have been secured or that they cover all habitat used by either species.

How Researchers Traced the Animals
The discoveries followed work across several kinds of evidence rather than a single field sighting. Researchers examined old fossils, photographs and specimens to develop leads before travelling to remote parts of New Guinea. The animals were then identified as still living there, according to the published study as described in the BBC report.
Flannery, co-author Kris Helgen and University of Papua researchers consulted elders from Tambrauw and Maybrat communities. Flannery said some elders had had contact with the modern world only since the 1960s. He also described the glider as sacred to some local people, saying they would neither hunt it nor speak its name. That cultural significance helps explain why community relationships were central to the research.
““The discovery of one lazarus taxon… is an exceptional discovery. But the discovery of two species, thought to have been extinct for thousands of years, is remarkable.””

Population and Protection Still Unknown
The report does not specify how many individuals researchers found, whether either species has a stable population, or how broadly the animals are distributed. It also does not provide enough detail to assess their conservation status or the extent of logging-related habitat loss. The phrase “thought to have been extinct for 6,000 years” describes the reported understanding of their disappearance; the supplied material does not detail the evidence or dating method behind that time estimate.
It remains unclear whether native title protections will be established, which forest areas they might cover, and what legal process would require logging to obtain local consent. Further surveys and conservation decisions will be needed to clarify the species’ numbers and risks.

Surveys and Forest Rights Ahead
Researchers and wildlife groups are seeking ways to secure native title for forest areas so logging cannot proceed without local consent, Flannery said. The source report does not give a timetable or confirm that an agreement has been reached. Further fieldwork would help determine where the possum and glider live and how many remain, while the outcome of forest-protection efforts will shape what happens to their habitat.

Key Questions
Which animals were reported in West Papua?
The study reports living pygmy long-fingered possums and ring-tailed gliders in remote New Guinea forests in West Papua.
Why were the species considered lost?
Researchers understood both species to have disappeared thousands of years ago. The BBC report says the possum was thought to have vanished from Australia during the Ice Age, but does not provide detailed dating evidence for the 6,000-year estimate.
How did researchers identify them?
They pieced together clues from fossils, photographs and museum specimens, visited remote locations and consulted elders from Tambrauw and Maybrat communities.
Are the animals at risk?
The report says logging is increasingly threatening the ring-tailed glider’s habitat. It gives no population estimates or formal conservation assessments for either species.
What happens next?
Scientists and wildlife groups are pursuing native title arrangements for forests, according to Flannery. The report does not confirm a completed agreement or set out a timetable; more surveys could clarify the animals’ distribution and numbers.
