![]() ![]() Because its feeding habits were highly specialized, E. Temperatures dropped and the grounds on which the animal grazed froze over, reducing the amount of available grass. But in the lead up to the Last Glacial Maximum, when the world’s ice sheets reached their greatest extent around 27,000 years ago, E. sibiricum teeth, the researchers were able to determine that the rhinoceros fed almost exclusively on tough, dry grasses. But according to the study authors, human hunters were likely not the cause of the animal’s extinction.īy studying stable isotopes in fossilized E. sibiricum’s demise also suggests that it overlapped in time with Neanderthals and early modern humans. “So Elasmotherium, with its apparent extinction date of 100,000 years ago or more, has not been considered as part of that same event.” “This megafaunal extinction event didn't really get going until about 40,000 years ago,” says Adrian Lister, a study co-author and a researcher at the Natural History Museum in London. This in turn places the Siberian unicorn’s extinction within a period known as the “Quaternary extinction event,” which saw the mass die-offs of ancient megafauna like the woolly mammoth, Irish elk and sabre-toothed cat. sibiricum was still alive 39,000 years ago-and possibly as recently as 35,000 years ago. “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.” “Some of the samples we studied were very contaminated which made the radiocarbon dating very challenging,” explains Thibaut Devièse, study co-author and principal investigator at Oxford University’s Radiocarbon Accelerator Unit. According to Gizmodo’s George Dvorsky, many of the specimens had been covered in preservation materials, requiring the researchers to use advanced dating techniques. Scientists from the Netherlands, Russia and the United Kingdom analyzed fossils from 23 E. The new study, published in the journal Nature Ecology & Evolution, took a more comprehensive look at a range of Siberian unicorn specimens. But these findings, based on individual fossils, were not conclusive. A complete skull held by the Natural History Museum in London was found to be less than 40,000 years old. sibiricum skull found in Kazakhstan was radiocarbon dated to 29,000 years ago. sibiricum’s extinction might be off by tens of thousands of years. Previous research has suggested that the commonly accepted timeline of E. sibiricum appears to have been relatively limited its fossils have been found primarily in Kazakhstan, western and central Russia, Ukraine, Azerbaijan and Uzbekistan. ![]() Its body was covered in shaggy hair, and the horn that jutted out from its skull was the largest of any known rhinoceros species, living or extinct. It weighed around 3.5 tons, but in spite of its massive heft, it had relatively slender limbs, suggesting it was an adept runner. sibiricum was a tremendous animal, and a strange one. sibiricum died out between 100,000 and 200,000 years ago, but as Natasha Frost reports for Quartz, a new study has found that the hulking unicorn actually survived until about 39,000 years ago, which places it roaming alongside modern humans and neanderthals.Į. Among them was the great Elasmotherium sibiricum, known as the “Siberian unicorn” for the huge horn that protruded from its skull. Five species of rhinoceroses exist today, but the lumbering creatures were once far more plentiful palaeontologists have identified 250 species that historically roamed throughout Africa, Eurasia and North America. ![]()
