Scientists find skull of enormous ancient dolphin in Amazon

Fossil of giant river dolphin found in Peru, whose closest living relation is in South Asia, gives clues to future extinction threats

Scientists have discovered the fossilised skull of a giant river dolphin, from a species thought to have fled the ocean and sought refuge in Peru’s Amazonian rivers 16m years ago. The extinct species would have measured up to 3.5 metres long, making it the largest river dolphin ever found.

The discovery of this new species, Pebanista yacuruna, highlights the looming risks to the world’s remaining river dolphins, all of which face similar extinction threats in the next 20 to 40 years, according to the lead author of new research published in Science Advances today. Aldo Benites-Palomino said it belonged to the Platanistoidea family of dolphins commonly found in oceans between 24m and 16m years ago.

Giganto, largest ever primate, died out due to diet change, say scientists

Giant primate ate bark and twigs after climate change turned sub-tropical environment into savannah

It was the largest primate ever to have roamed the Earth, but just why – and when – our distant cousin “giganto” ended up extinct has been something of a mystery.

Now researchers say the enormous ape was victim of an unfortunate choice of food when its preferred snacks became scarce.

Bear-clawed cavern discovered in Spain ‘opens new door on prehistory’

Researchers hail ‘world-class discovery’ that suggests cave bears may have lived farther south than thought

Researchers exploring a cave system in south-east Spain have discovered a huge cavern, sealed off for millennia, hung with huge stalactites and gouged by the claws of long-extinct cave bears, which, they claim, “opens a new door on prehistory”.

The find was made at the Cueva del Arco, a collection of caves in the Almadenes gorge near the Murcian town of Cieza. Although the site had already yielded evidence of settlements stretching back 50,000 years – making it one of the few places in the eastern Iberian peninsula where the transition from Neanderthals to modern humans can be documented – experts digging there suspected it harboured further discoveries.

Wanted lost species: blind salamander, tap-dancing spider and ‘fat’ catfish

A Texas-based group has drawn up a new list of as part of its quest to find species lost to science and possibly extinct

A blind salamander, a tap-dancing spider and a “fat” catfish that has been likened to the Michelin man are among a list of vanished species that one US-based conservation group is aiming to rediscover in the wild and help protect.

The Texas-based group, called Re:wild, has drawn up a new list of the “25 most wanted lost species” as part of its quest to find species lost to science and possibly extinct.

This article was amended on 9 February 2022 to clarify that a fungus is not a type of plant.

Firm raises $15m to bring back woolly mammoth from extinction

Scientists set initial sights on creating elephant-mammoth hybrid, with first calves expected in six years

Ten thousand years after woolly mammoths vanished from the face of the Earth, scientists are embarking on an ambitious project to bring the beasts back to the Arctic tundra.

The prospect of recreating mammoths and returning them to the wild has been discussed – seriously at times – for more than a decade, but on Monday researchers announced fresh funding they believe could make their dream a reality.

Female cave lion cub named Sparta in Russia’s Yakutia region may even have traces of mother’s milk in it

Scientists have said that an astonishingly well-preserved cave lion cub found in Siberia’s permafrost lived 28,000 years ago and may even have traces of its mother’s milk in it.

The female cub, named Sparta, was found at the Semyuelyakh River in Russia’s Yakutia region in 2018 and a second lion cub called Boris was found the year before, according to a study published in the Quaternary journal.

Global study finds that species numbers reported in the wild fell sharply between 1990 and 2015

The number of wild bee species recorded by an international database of life on Earth has declined by a quarter since 1990, according to a global analysis of bee declines.

Researchers analysed bee records from museums, universities and citizen scientists collated by the Global Biodiversity Information Facility, (GBIF) a global, government-funded network providing open-access data on biodiversity.

Calf carcass from thawing ground in north-east region of Yakutia found with many internal organs intact

A well-preserved ice age woolly rhino with many of its internal organs still intact has been recovered from the permafrost in Russia’s extreme northern region.

Russian media reported on Wednesday that the carcass was revealed by thawing permafrost in Yakutia in August. Scientists are waiting for ice roads in the Arctic region to become passable to deliver the animal to a laboratory for studies in January.

Rewild to mitigate the climate crisis, urge leading scientists

Restoring degraded natural lands highly effective for carbon storage and avoiding species extinctions

Restoring natural landscapes damaged by human exploitation can be one of the most effective and cheapest ways to combat the climate crisis while also boosting dwindling wildlife populations, a scientific study finds.

If a third of the planet’s most degraded areas were restored, and protection was thrown around areas still in good condition, that would store carbon equating to half of all human caused greenhouse gas emissions since the industrial revolution.

Sixth mass extinction of wildlife accelerating, scientists warn

Analysis shows 500 species on brink of extinction – as many as were lost over previous century

The sixth mass extinction of wildlife on Earth is accelerating, according to an analysis by scientists who warn it may be a tipping point for the collapse of civilisation.

More than 500 species of land animals were found to be on the brink of extinction and likely to be lost within 20 years. In comparison, the same number were lost over the whole of the last century. Without the human destruction of nature, even this rate of loss would have taken thousands of years, the scientists said.

Giant river animals on verge of extinction, report warns

Populations of great freshwater species, from catfish to stingrays, have plunged by 97% since 1970

Populations of the great beasts that once dominated the world’s rivers and lakes have crashed in the last 50 years, according to the first comprehensive study.

Some freshwater megafauna have already been declared extinct, such as the Yangtze dolphin, and many more are now on the brink, from the Mekong giant catfish and stingray to India’s gharial crocodiles to the European sturgeon. Just three Chinese giant softshell turtles are known to survive and all are male. Across Europe, North Africa and Asia, populations have plunged by 97% since 1970.

‘Frightening’ number of plant extinctions found in global survey

Study shows 571 species wiped out, and scientists say figure is likely to be big underestimate

Human destruction of the living world is causing a “frightening” number of plant extinctions, according to scientists who have completed the first global analysis of the issue.

They found 571 species had definitely been wiped out since 1750 but with knowledge of many plant species still very limited the true number is likely to be much higher. The researchers said the plant extinction rate was 500 times greater now than before the industrial revolution, and this was also likely to be an underestimate.

Cull invasive mammals to save island species, experts urge

Posted on by

Move ‘would save 10% of all endangered birds, mammals, amphibians and reptiles’

Nearly 10% of the world’s bird, mammal, amphibian and reptile species currently on the brink of extinction could be saved by killing invasive mammals such as cats and rats on 169 islands, according to a new study.

Islands comprise just 5.3% of the Earth’s landmass yet have experienced 75% of known bird, mammal, amphibian and reptile extinctions since 1500. More than a third of species currently classified as “critically endangered” on the IUCN Red List are found on islands, with many particularly vulnerable to just eight species – including feral pigs, dogs, goats and mongooses – introduced by humans.
