Sibian & Adult Unicorns & # 39; A New World's Walking on Earth with New Zealand



Adding up to 3,500kg, Elasmotherium sibiricum-The extinct wild canal that is known as the "Siberia Uncooked" – thought that it had been extinct for as long as 200,000 years ago. An updated fossil analysis indicates that this particular species was still around 39,000 years ago, and that the Ice Age situation, not human hunters, contributing to the decline.

Paleontologists know about 250 seabird species, and only five are still today. Among the most spectacular of these habitats were Elasmotherium sibiricum-Seibian Unicorn. For the Neanderthals and the new people living by side and her; hunting this great creature in the eastern Europe and Central Asia, it should have been a very scary look. Fossil evidence is a recommendation Elasmotherium is covered with 3.5 tons, covered in a thick gray coat, and an air resistance of biblical sections, & # 39; possibly as long as three feet (1 meter) length.

Although it was very spectacular, the Siberian unicorns grew last. Fossil presence praised a final closing date between 200,000 and 100,000 years ago, long before its late Quaternary megafaunal massive collapse, which was in the region of 40,000 years ago. New research published this week in Nature Ecology & Evolution now offers a more reliable estimate, and # 39; give up their decline Elasmotherium between 39,000 and 35,000 years ago. Thus, the decline of the Siberia unicorn can now be linked to the late Quaternary megafaunal collapse, an event that saw the end of wool women, Ireland's bird, and an informed cat.

Writers in their new study, led by Adrian Lister from the Natural History Museum in London, said researchers "there is no complete data, genetic analysis or ecological measurement of its & # 39; this species [had] has been adopted, "which explains why the pre-mortal estimate has been so long ago. The new study will impact on these problems, and bring it to an end. including updating the use of fossil handling techniques.

For the inspection, an international team of researchers from the UK, Holland, and Russia took a deeper look at 23 Elasmotherium Examples, including a pristine skull reserved at the Natural History Museum. Enhanced radiocarbon data technology has progressed to the revised exclusion dates; many of the samples were distributed in conservation materials, which required careful preparation for carbon data.

"Some of the samples we were learning about the pollution made by the radiocarbon data were extremely challenging," said Thibaut Devièse, a researcher at Oxford Archeology School and co-author of the survey, in recited. "For this reason, we used a new method of pulling one aminoidal bone collagen to ensure that the results are very correct."

In addition, the researchers respond, for their & # 39; the first time ever, to drag DNA from here Elasmotherium fossils. The genetic study that introduced the Siberian unicorn division of new seabirds was around 43 million years ago, "a debate situation based on fossil evidence and confirmed that the two climbs donated by the Eocene, "wrote the researchers in the study. These Ice Age seals are the last species of a "distinctive and ancient" series, "according to the research.

There was a Siberia unicorn living with people today and Neanderthal. That old century has not been to believe in these great tales so horrible & # 39; It's like it would be like. People are early in the early years, maybe they look like it Homo erectus, to seal seals in the Philippines for around 700,000 years ago. But although there were seals on the hominin menu, this new search is a & # 39; recommends that climate change, and not hunters, be the responsibility ElasmotheriumSouthwest

These windows, as we are now familiar with the new research, lived during the Ice Age just before the end of the highest-level glaciation with the ice divisions to & # 39; covering the largest area, about 26,500 years ago. The ground was subject to drama drama systems during this century, which caused illness, growth, fall in sea levels, and regular erosion of glaciers. This bad breach was fatal for many genres, Elasmotherium among them.

For the one-to-one Siberia, this meant habitat loss, and as a result, how did the place go? disappeared, as the new study thinks. In examinations, Lister and her colleagues examined a stable isotope ratio of fossil rhinoid teeth. The researchers sought to link between different plants with dental levels of dental nitrogen isototides. There was a Siberia unicorn, as this analysis revealed, living in a dry steam environment where they were going to; walking on hard, dry grass. The rhinos, with their highly specialized grazing life and numbers of numbers, can not be changed quickly enough for rapidly changing conditions, depending on the survey.

So, there was a change in climate, and not humans, for the decline E. sibiricumInterestingly, it's a decision that's a n; Looks well with a similar, but unrelated research, in which scientists say that people were not responsible for many to have an impact on the Ice Age. Unfortunately, it is not possible to say how the sixth mass has gone to an end, which is certainly our risk.
