Scientists have recently discovered that a giant rhino, known as the Siberian unicorn, survived until at least 39,000 years ago – much longer than previously thought.
New evidence shows the hefty beast may have eventually died out because it was such a picky eater.
Scientists say knowing more about the animal’s extinction could help save the remaining rhinos on the planet.
Rhinos are in particular danger of extinction because they are very picky about their habitat, said Prof Adrian Lister of the Natural History Museum, London, who led the study.
“Any change in their environment is a danger for them,” he said.
Today there are just five remaining species of rhino. Very few survive outside national parks and reserves due to persistent poaching and habitat loss over many decades.
By studying fossilised rhinos, scientists can learn more about the fate of the many prehistoric rhino species that once roamed the planet and how they adapted to climate change and human pressures.
