Fossil of ‘largest snake to have ever existed’ found in western India

Posted on by

Scientists estimate Vasuki indicus was up to 15m long, weighed a tonne and would have constricted its prey

Fossil vertebrae unearthed in a mine in western India are the remains of one of the largest snakes that ever lived, a monster estimated at up to 15 metres in length – longer than a T rex.

Scientists have recovered 27 vertebrae from the snake, including a few still in the same position as they would have been when the reptile was alive. They said the snake, which they named Vasuki indicus, would have looked like a large python and would not have been venomous.

The French aristocrat who understood evolution 100 years before Darwin – and even worried about climate change

Georges-Louis Leclerc proposed species change and extinction back in the 1740s, a new book reveals

Shortly after Charles Darwin published his magnum opus, The Origin of Species, in 1859 he started reading a little-known 100-year-old work by a wealthy French aristocrat.

Its contents were quite a surprise. “Whole pages [of his book] are laughably like mine,” Darwin wrote to a friend. “It is surprising how candid it makes one to see one’s view in another man’s words.”

In later editions of The Origin of Species, Darwin acknowledged Georges-Louis Leclerc, Comte de Buffon, as one of the “few” people who had understood that species change and evolve, before Darwin himself.

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.

Traits associated with the neurodevelopmental disorder could have helped early humans when foraging for food

Traits common to attention deficit hyperactivity disorder (ADHD), such as distractibility or impulsivity, might have been an evolutionary advantage for our ancestors by improving their tactics when foraging for food, researchers have said.

ADHD is a neurodevelopmental disorder with symptoms including impulsiveness, disorganisation and difficulty focusing. While estimates of prevalence have varied, diagnoses have been rising in many countries, including the UK.

Tritylodonts, mid-sized mammal-related herbivores, roamed the area’s deserts 200m years ago

Scientists have discovered an “extremely rare” set of fossils at Lake Powell that the National Park Service (NPS) is calling one of the most important vertebrate discoveries in the US this year.

The findings, revealed this week, include skulls and teeth from dozens of mid-sized, mammal-related herbivores called tritylodonts that once roamed the region’s vast desert. The bones lay hidden in the sandstone walls of the reservoir for roughly 180m years before a lucky discovery in March.

Fossils found in Peru from extinct species show it may have had body mass of 85-340 tonnes – heavier than blue whales

The fossilised bones of an ancient creature that patrolled coastal waters 40m years ago belong to a newly discovered species that is a contender for the heaviest animal ever to have existed on Earth.

Fossil hunters discovered remnants of the enormous and long-extinct whale in a rock formation in the Ica desert of southern Peru. Fully grown adults might have weighed hundreds of tonnes, researchers believe.

Discovery in China challenges view of early mammals as ‘fodder’ for dinosaurs, say researchers

Whether they had sharp teeth, vicious claws or were simply enormous, dinosaurs were creatures to be feared. But a newly identified fossil shows that, at least sometimes, the underdog bit back.

Experts revealed the 125m-year-old fossil that froze in time after being taken on by a small mammal a third of its size. They are tangled together, the mammal’s teeth sunk into the beaked dinosaur’s ribs, its left paw clasping the beast’s lower jaw.

Elk tooth pendant unearthed in Siberia is first prehistoric artefact to be linked to specific person using genetic sleuthing

Scientists have used a new method for extracting ancient DNA to identify the owner of a 20,000-year-old pendant fashioned from an elk’s canine tooth.

The method can isolate DNA that was present in skin cells, sweat or other body fluids and was absorbed by certain types of porous material including bones, teeth and tusks when handled by someone thousands of years ago.

The technique – known as proteomics – could bring new insights into the past two million years of humanity’s history

Tiny traces of protein lingering in the bones and teeth of ancient humans could soon transform scientists’ efforts to unravel the secrets of the evolution of our species.

Researchers believe a new technique – known as proteomics – could allow them to identify the proteins from which our predecessors’ bodies were constructed and bring new insights into the past 2 million years of humanity’s history.

Bipedalism in humans may have come from foraging in treetops, research suggests

Walking on two legs may not have been linked to environmental shifts, as previously thought

The ancestors of humans may have begun moving on two legs to forage for food among the treetops in open habitat, researchers have suggested, contradicting the idea that the behaviour arose as an adaptation to spending more time on the ground.

The origins of bipedalism in hominins around 7m years ago has long been thought to be linked to a shift in environment, when dense forests began to give way to more open woodland and grassland habitats. In such conditions, it has been argued, our ancestors would have spent more time on the ground than in the trees, and been able to move more efficiently on two legs.

‘The sheer scale is extraordinary’: meet the titanosaur that dwarfs Dippy the diplodocus

One of the largest creatures to have walked the Earth is to become the Natural History Museum’s new star attraction

It will be one of the largest exhibits to grace a British museum. In spring, the Natural History Museum in London will display the skeleton of a titanosaur, a creature so vast it will have to be shoehorned into the 9-metre-high Waterhouse gallery.

One of the most massive creatures ever to have walked on Earth, Patagotitan mayorum was a 57-tonne behemoth that would have shaken the ground as it stomped over homelands which now form modern Patagonia. Its skeleton is 37 metres long, and 5 metres in height – significantly larger than the museum’s most famous dinosaur, Dippy the diplodocus, which used to loom over its main gallery.

Group’s earliest primogenitor was probably a diminutive creature with a long snout, researchers suggest

The last common ancestor of today’s placental mammals – a group that includes humans, whales and armadillos – was probably a shrew-like creature with a long snout, researchers have revealed.

The forerunners of mammals are believed to have split from what eventually became reptiles around 320m years ago, but it was not until some time between 70 and 80m years ago that placental mammals arose.

Research suggests species coexisted for more than 1,000 years and uncovers possible ‘exchange of ideas’

Modern humans lived alongside Neanderthals for more than 1,000 years in Europe, according to research that suggests the two species may have imitated each other’s jewellery and stone tools.

Previously, it was known that humans and their ancient relatives existed at the same time on the European continent for more than 6,000 years and that the two species interbred on several occasions. But the extent of their interactions remains the focus of scientific investigation.

Researchers think they may have solved enduring mystery of where Typhloesus wellsi sits on tree of life

The mystery of a bizarre creature dubbed the “alien goldfish”, which has baffled fossil experts for decades, may have been solved, according to scientists who say the animal appears to have been some sort of mollusc.

Typhloesus wellsi lived about 330m years ago and was discovered in the Bear Gulch Limestone fossil site in Montana in the late 1960s, with the remains of other species subsequently identified.

Remains from Chad desert provoke rancorous dispute over whether species was earliest to walk upright

It is a dispute that has taken a long time to reach boiling point. Seven million years after an apelike creature – since nicknamed Toumaï – traversed the landscape of modern Chad, its means of mobility has triggered a dispute among fossil experts. Some claim this was the oldest member of the human lineage. Others that it was just an old ape.

The row, kindled by a paper in Nature, last week led scientists to denounce opponents while others accused rivals of building theories on “less than five minutes’ observation” .
