New Guinea: Two marsupials lost for 6,000 years rediscovered

In March 2026, an Australian research team led by zoologist Tim Flannery published two studies with surprising results: On the remote Vogelkop Peninsula in northwestern New Guinea, two marsupial species were found alive that had previously been known only from fossils approximately 6,000 to 7,500 years old. Such rediscoveries are

Rediscoveries in 2025: These animal species were considered lost or extinct

Species do not simply disappear just because no one has seen them for a long time. And they are just as little “saved” just because they suddenly reappear. Rediscoveries mark a narrow line between hope and uncertainty: they show that life can endure – often, however, only barely. In 2025,

Rediscovery: Rare kingfisher reappears after 13 years

The Bismarck kingfisher (Ceyx websteri) was considered lost for almost 13 years. Since the last confirmed record in 2012, the species had gone unobserved, raising fears that it might already be extinct. In May 2025, however, the species was confirmed again in Papua New Guinea: researcher John Lamaris documented a

Mussau Triller: Lost Bird Species Rediscovered After 44 Years

The Mussau triller (Lalage conjuncta), last documented in 1979, was rediscovered in June of this year by Australian bird photographer Joshua Bergmark during a tour with a group of birdwatchers. This songbird species, part of the cuckooshrike family, is endemic to Mussau Island, located in the Bismarck Archipelago north of

Tongatapu rail

The only specimen is now lost Quite a few bird species of the past were described from only a single specimen that is now lost. One of them is the Tongatapu rail. Of this rail species (family Rallidae), historical reports and descriptions have survived that are based on observations and

Tonga-Skink (Tachygyia microlepis)
The Tonga ground skink is known from only two specimens collected on Tongatapu in the early 19th century. The species reached a snout–vent length of almost 18 centimeters, plus tail.

Tongan Ground Skink

From the South Pacific to the museum—the last Tongan ground skinks The Tongan ground skink, a giant lizard, is known only from two specimens that are now housed in the Natural History Museum of Paris. The French doctors and naturalists Jean-René-Constant Quoy and Joseph Paul Gaimard collected the two animals

Guam kingfisher: Reintroduction to Palmyra after extinction in the wild

The Guam kingfisher, last seen in the wild in 1986, is now poised to return to nature. After successful breeding in captivity, it is planned to release the offspring of this nearly extinct bird species on Palmyra Atoll. This remote atoll, located about 1,600 kilometers southwest of Hawaii, offers a

Newly discovered animals 2023

It is said that between 11,000 and 58,000 animal and plant species irreversibly go extinct each year, but there is also good news: around 18,000 new species are described and named by taxonomists each year; this number includes extinct or fossilized organisms, as well as bacteria and viruses. Even in

anas aucklandica
According to ornithologists Olson and Jouventin, the extinct Amsterdam duck was similar to the still extant, likewise flightless Auckland teal (Anas aucklandica; see image).

Nevertheless—or perhaps precisely because of this—the two islands were frequently visited by early seafarers and the animals that traveled with them, so that all endemic birds there had already been wiped
