Weighing up to 7,700 pounds, Elasmotherium sibiricum—an extinct hairy rhino popularly known as the “Siberian unicorn”—was thought to have disappeared as long as 200,000 years ago. An updated fossil analysis suggests this formidable species was still around some 39,000 years ago, and that Ice Age conditions, not human hunters, contributed to its demise.

Paleontologists know of around 250 rhino species, of which only five still exist today. Among the most spectacular of these rhinos was Elasmotherium sibiricum—the Siberian unicorn. For the Neanderthals and modern humans who lived alongside and possibly hunted this massive creature in Eastern Europe and Central Asia, it must’ve been an impressive and deeply intimidating sight. Fossil evidence suggests Elasmotherium weighed over 3.5 tons, was covered in a thick coat of hair, and sported a horn of biblical portions, possibly as long as three feet (1 meter) in length.

  So many animals will go extinct in the next 50 years that it will take Earth at least 3 million years to recover, a study has found Mammals are facing high rates of extinction as humans destroy their habitats. In a new study, Danish researchers conclude that so many mammal species will go extinct in the next 50 years that the planet's evolutionary diversity won't recover for at least 3 million years.

A long- extinct animal known as the Siberian unicorn —which was actually a long-horned rhinoceros—may have walked the Earth 29,000 years ago, at the same time as prehistoric humans , researchers say. Until now, the Elasmotherium sibiricum was thought to have vanished 350,000 years

With a new discovery, paleontologists have found evidence that a Siberian “ unicorn ” likely walked the earth at the same time as humans . Researchers from Tomsk State University found a well-preserved skull belonging to a Siberian unicorn near the village of Kozhamzhar in modern -day

Impressive though it may have been, the Siberian unicorns eventually died out. Previous fossil dating suggested an expiry date at some point between 200,000 and 100,000 years ago, long before the large-scale late Quaternary megafaunal extinction, which got rolling around 40,000 years ago. New research published this week in Nature Ecology & Evolution is now offering a more reliable estimate, dating the demise of Elasmotherium at some point between 39,000 and 35,000 years ago. The extinction of the Siberian unicorns, therefore, can now be connected to the late Quaternary megafaunal extinction, an event that witnessed the end of the wooly mammoth, Irish elk, and saber-toothed cat.

Writing in their new study, led by Adrian Lister from the Natural History Museum in London, the researchers said “no absolute dating, genetic analysis or quantitative ecological assessment of this species [had] been undertaken,” which explains why the prior extinction estimate was so far off. The new study overcomes these shortcomings, and includes the use of updated fossil dating techniques.

But cutting-edge research has shown the beast shared the earth with early modern humans right up until 35,000 years ago. The ancient rhino species known as Elasmotherium sibericum ( Siberian unicorn ), because of its extraordinary single horn, was thought to have become extinct between 200

For the study, an international team of researchers from the UK, Netherlands, and Russia took a closer look at 23 Elasmotherium specimens, including a pristine skull kept at the Natural History Museum. An improved radiocarbon dating technique resulted in the revised extinction dates; many of the samples were slathered in preservation materials, requiring careful preparation for the carbon dating.

“Some of the samples we studied were very contaminated which made the radiocarbon dating very challenging,” Thibaut Devièse, a researcher at Oxford’s School of Archaeology and a co-author of the study, said in a statement. “For this reason we used a novel method of extracting a single amino acid from the bone’s collagen in order to ensure highly accurate results.”

In addition, the researchers succeeded, for the first time ever, in extracting DNA from the Elasmotherium fossils. The ensuing genetic analysis showed that Siberian unicorns split from modern rhinos around 43 million years ago, “settling a debate based on fossil evidence and confirming that the two lineages had diverged by the Eocene,” the researchers wrote in the study. These Ice Age rhinos are the last species of a “highly distinctive and ancient lineage,” according to the research.

New research suggests that a species of unicorn -like horned rhinos went extinct much later than previously thought. Researchers from Tomsk State University in Russia recently analyzed the well-preserved skull fossils of an Elasmotherium sibiricum, also known as the " Siberian unicorn ," that was

Siberian unicorns lived alongside anatomically modern humans and Neanderthals. That ancient hominids may have preyed upon these oversized rhinos is not as outrageous a proposition as it may seem. Early humans, likely a form of Homo erectus, were hunting rhinos in the Philippines around 700,000 years ago. But while rhinos were on the hominid menu, this new research suggests climate change, and not hunters, was responsible for Elasmotherium’s demise.

These rhinos, as we now know from the new research, lived during the Ice Age just prior to the Last Glacial Maximum—the stage at which the ice sheets covered their largest area, around 26,500 years ago. Earth was prone to dramatic climate shifts during this period, producing drought, desertification, a drop in sea levels, and the steady encroachment of glaciers. These climactic disruptions proved fatal to many species, Elasmotherium among them.

For the Siberian unicorn, this meant a loss of habitat, and by consequence, the disappearance of a critical food source, as the new study hypothesizes. In experiments, Lister and his colleagues analyzed stable isotope ratios from the fossilized rhino teeth. The researchers sought to link various plants with the levels of carbon and nitrogen isotopes in their teeth. Siberian unicorns, as this analysis revealed, lived in a dry steppe environment where they chomped on tough, dry grasses. The rhinos, with their highly specialized grazing lifestyle and naturally low population numbers, could not adapt quickly enough to the rapidly changing conditions, the study suggests.

Neanderthals might not be the hunched cavemen we thought they were, study says Neanderthals may not have sported the barrel-chested bodies and hunched posture we see in museums and textbooks, according to a new study. require(["medianetNativeAdOnArticle"], function (medianetNativeAdOnArticle) { medianetNativeAdOnArticle.getMedianetNativeAds(true); }); The first 3D virtual reconstruction of a Neanderthal ribcage has revealed that they had straighter spines and a greater lung capacity than modern humans. The findings about the Neanderthal, also spelled Neandertal, were published Tuesday in the journal Nature Communications.

Now scientists have found new evidence to suggest that this unicorn -like creature may have actually survived until as recently as 26,000 years ago, meaning that it would have lived alongside modern humans for many thousands of years. The discovery was made after fossil fragments were unearthed

Unicorns are real, or at least were real in prehistoric times. It was long believed that the last of the Siberian Unicorns died out several hundreds of Called the Elasmotherium sibiricum, these animals had more in common with modern -day rhinos than horses and deer and had one massive horn.

A changing climate, and not humans, were thus responsible for the demise of E. sibiricum. Interestingly, it’s a conclusion that jibes well with similar, but unrelated, research, in which scientists claim that humans weren’t responsible for many megafaunal extinctions of the Ice Age. Sadly, the same cannot be said for the ongoing sixth mass extinction, which is most certainly our fault.
