Plot twist – "unicorns" apparently did the Earth once, but they were more like rhinos than horses.
Researchers are learning more about the fuzzy rhinos called "Siberian Unicorns" after DNA tests of fossils provide insight into their extinction. Paleontologists say they were around much longer than originally thought, living up to at least 39,000 years ago. This means the animals lived among people.
They were previously thought to have gone extinct between 100,000 to 200,000 years ago.
The study also says the Elasmotherium sibiricum Probably died out because climate change wiped out their grasslands and food sources, not because of humans.
The team's research was published in the journal Nature Ecology and Evolution.

This photo taken on July 28, 2015 on the archaeological site of Angeac-Charente, southwestern France, shows fossilized dinosaur bones during their unearthing process, a femur (Sauropod dinosaur's femur) and an Ornithomimosaur (Ostrich Dinosaur, a new species of dinosaur identified on the site, where at least 43 specimen have been inventoried) dinosaur's shinbone (still in a clay gangue). The Angeac dinosaur fossil deposit is unique in France by its abundance; or the thousands of fossils unearthed there, two species until then unknown have been identified.

TORONTO, ON – JUNE 2: A fossil cast of an Archaeopteryx lithographica, which lived in the Late Jurassic period, 148 million years ago. A new study suggests feathers were less common among dinosaurs than previously believed. Interview with the ROM's Dr. David Evans about his new research that could shake up how we imagine dinosaurs.

Photo taken on July 29, 2014 shows a 34 cm long phalanx of a dinosaur Sauropoda, discovered during excavations in Angeac-Charente, central-western France. A student in paleontology found the fossil on July 25. The world's largest Sauropoda thigh bone was found on this site in summer 2010. The site was discovered in 2008 and is actively searched since January 2010. AFP PHOTO / JEAN PIERRE MULLER read JEAN PIERRE MULLER / AFP / Getty Images)

LAS VEGAS – SEPTEMBER 30: One of the world's largest set of shark jaws comprised of about 180 fossil teeth from the prehistoric species, Carcharocles megalodon, which grew to the size of a school bus, is displayed at the Venetian Resort Hotel Casino September 30, 2009 in Las Vegas, Nevada. Auctioneers Bonhams & Butterfields hope the fossil will take about $ 900,000-1.2 million when it is auctioned off on October 3 at the Venetian as part of their Natural History auction. The centerpiece of the lot of 50 fossils being auctioned is a 66-million-year-old Tyrannosaurus rex skeleton dubbed 'Samson.' The 40-foot-long female fossil dinosaur, excavated in South Dakota in 1992, contains about 170 bones and is said to be the third most complete T. rex skeleton ever unearthed. Bonhams & Butterfields hoping Samson will get more than USD 6 million at the auction. (Photo by Ethan Miller / Getty Images)

NEW YORK – MAY 10: A Fossil of a Microraptor from a 130-million year old forest that existed in what is now Liaoning Province, China is displayed at the new exhibition 'Dinosaurs: Ancient Fossils, New Discoveries' at the American Museum of Natural History May 10, 2005 in New York City. The exhibition, which will open to the public on May 14 and runs on January 8, uses recent fossil finds, computer simulations and life-size models to trace changes in the thinking of dinosaur biology over the past two decades.
