Species extinction is a natural phenomenon, but sometimes, as Mark Twain wrote: “The reports of my death are greatly exaggerated.” The Endangered Species Act has been used for good to help some species and for political reasons to stop or inhibit mines, logging, farming, and many other activities. Below is a collection of articles which show that some reports of extinction were in error. Sometimes, “settled science” is wrong. (Note, most links have photos.)
Long-lost Tasmanian tiger may have been found
September 6, 2017
Do Tasmanian tigers still exist? A few trackers believe they have found evidence — releasing alleged footage of proof. The grainy and fleeting videotape, according to The Mercury, showed Tasmanian tigers (also known as thylacines) in their natural state: a thylacine walking slowly at a distance, a thylacine nose at the camera lens, and a thylacine with a cub.
Official accounts, according to The Mercury, suggest the thylacine became extinct on the Australian mainland more than 2000 years ago, although unverified “sightings” occur across many states of Australia from time to time. (Read more)
Boy finds ‘extinct’ frog in Ecuador and helps revive species
July 7, 2017
A school-age boy has rediscovered an Ecuadorian frog considered extinct for at least 30 years. The animal has now successfully bred in captivity.
The colourful Jambato harlequin frog (Atelopus ignescens) was once so widespread in Ecuador that it turned up in people’s homes, was something children played with and was used as an ingredient in traditional medicine. Then it was suddenly wiped out, probably by a combination of climate change and fungal disease. (Read more)
Frog not sighted in 30 years and declared extinct reappears in Costa Rica
June 07, 2017
SAN JOSE – Costa Rican scientists reported the reappearance of an endemic frog species that had not been sighted for three decades (Heredia robber frog, Craugastor escoces.) It was declared extinct in 2004 by the International Union for Conservation of Nature (UICN). (Read more)
Seychelles snail, believed extinct due to climate change, found ‘alive and well,’ says group
Sep 8, 2014, NAIROBI, Kenya (AP) — A snail once thought to have been among the first species to go extinct because of climate change has reappeared in the wild. The Aldabra banded snail, declared extinct seven years ago, was rediscovered on Aug. 23 in the Indian Ocean island nation of Seychelles. The mollusk, which is endemic to the Aldabra coral atoll — a UNESCO World Heritage Site — had not been seen on the islands since 1997, said the Seychelles Islands Foundation. Read more And here
‘Extinct’ corpse-eating fly back from the dead
July 9, 2013
Behold the bone-skipper, high in the running for the strangest fly on Earth. For the bone-skipper, fresh carcasses just won’t do. No, these flies prefer large, dead bodies in advanced stages of decay. And unlike most flies, they are active in early winter, from November to January, usually after dark. They also disappeared from human notice and were declared extinct for more than a century. That’s why they’ve often been considered almost mythical or legendary, said Pierfilippo Cerretti, a researcher at the Sapienza University of Rome. In the past few years, three species of bone-skipper have been rediscovered in Europe, setting off a buzz among fly aficionados. (Read more)
Biologists find rare snake near Gila River
July 6, 2013
The northern Mexican garter snake was once thought to be extinct in New Mexico. Not so, according to biologists at the Albuquerque BioPark. They found three of the snakes in early June near the Gila River and another three later in the month. Two of the snakes were studied, tagged and released. The remaining four were brought to the Albuquerque Zoo to establish a breeding population.(Read more)
An ‘extinct’ frog makes a comeback in Israel
Jerusalem, June 4, 2013 — The first amphibian to have been officially declared extinct by the International Union for Conservation of Nature (IUCN) has been rediscovered in the north of Israel after some 60 years and turns out to be a unique “living fossil,” without close relatives among other living frogs.
The Hula painted frog was catalogued within the Discoglossus group when it was first discovered in the Hula Valley of Israel in the early 1940s. The frog was thought to have disappeared following the drying up of the Hula Lake at the end of the 1950s, and was declared extinct by the IUCN in 1996. As a result, the opportunity to discover more about this species’ history, biology and ecology was thought to have disappeared. (Read more)
Cute rodent species surfaces after 113 years
May 19, 2011
Scientists thought a mysterious guinea pig-sized rodent species that hadn’t been seen in 113 years was long extinct. Until one of them ambled up to two volunteer naturalists at a nature reserve in Colombia two weeks ago. The nocturnal animal, the elusive red-crested tree rat, turned up just as the scientists were heading off to bed, at 9:30 p.m. on May 4. It spent two hours watching as the volunteer biologists took photos of it, then calmly ambled off into the darkness. (Read more)
India team uncovers 12 frog species
Sep 18, 2011, New Delhi – Years of combing tropical mountain forests, shining flashlights under rocks and listening for croaks in the night have paid off for Indian scientists who have discovered 12 new frog species plus three others thought to have been extinct. (Read more)
Pygmy tarsier, a tiny primate, rediscovered in Indonesia
November 19, 2008
The tiny Furby-like pygmy tarsier, presumed to be extinct, was found during a recent expedition to Indonesia. And the cuddly, huge-eyed nocturnal critter is the very definition of cute. Gursky-Doyen of Texas A&M University traveled into the mountains of Sulawesi Island in Indonesia to confirm that the pygmy tarsier was unequivocally extinct, but ended up becoming the first person in more than 80 years to spot a live one.

Ivory-Billed Woodpecker Rediscovered in Arkansas
April 28, 2005
A group of wildlife scientists believe the ivory-billed woodpecker is not extinct. They say they have made seven firm sightings of the bird in central Arkansas. The landmark find caps a search that began more than 60 years ago, after biologists said North America’s largest woodpecker had become extinct in the United States. (Read more) Note: this contention is still controversial – see here.
Coelacanths (seel-a-canths) were once known only from fossils and were thought to have gone extinct approximately 65 million years ago (mya), during the great extinction in which the dinosaurs disappeared. Today, there are two known living species.
The first living coelacanth was discovered in 1938. For many years, living coelacanths were known only from the western Indian Ocean, primarily from the Comoros Islands, but in September 1997 and again in July 1998, coelacanths were captured in northern Sulawesi, Indonesia, nearly 6,000 miles to the east of the Comoros.

The moral of this story is that even “settled science” can be wrong. A good scientist should always be skeptical.
Related: For the past several years alarmist scientists have claimed that humans are causing “the sixth mass extinction” on Earth. Smithsonian paleontologist Doug Erwin debunks this claim in the article: “Earth Is Not in the Midst of a Sixth Mass Extinction.”
Erwin is one of the world’s experts on the End-Permian mass extinction, an unthinkable volcanic nightmare that nearly ended life on earth 252 million years ago. He proposed that earth’s great mass extinctions might unfold like these power grid failures: most of the losses may come, not from the initial shock—software glitches in the case of power grid failures, and asteroids and volcanoes in the case of ancient mass extinctions—but from the secondary cascade of failures that follow. These are devastating chain reactions that no one understands.
