Plot Twist – "Unicorns" once apparently roamed the earth, but they were more rhinos than horses.
Researchers learn more about the fuzzy rhinos called "Siberian unicorns" after fossil DNA testing has revealed their extinction. Paleontologists say they last much longer than originally thought and lived at least 39,000 years ago. This means that the animals lived among the humans.
It was believed that they were extinct 100,000 to 200,000 years ago.
The study also says that Elasmotherium sibiricum is likely to have died because of climate change that has destroyed grasslands and food sources, not humans.
The team's research has been published in the journal Nature Ecology and Evolution.
