Large, four-legged beasts, each with a single horn growing from its head, once ambled across part of western Siberia, in what is now Kazakhstan.
Sometimes referred to as “unicorns” because of their single horns, these animals were originally thought to have gone extinct 350,000 years ago. However, fossils from a new dig site place the hefty creatures in the region as recently as 29,000 years ago, according to a recent study.
In spite of their magical-sounding nickname, these bruisers share little in common with the graceful and delicate horselike creatures described in song and story and pictured in medieval tapestries. A 1923 publication by paleontologist Henry Fairfield Osborn estimated the creatures to be larger than any of the modern rhino species. Artists’ reconstructions hint at a burly build and body plan that resemble that of the animals’ extant cousins. And the beasts go by an equally cumbersome name: Elasmotherium sibiricum (ee–laz–moh–THEER–ee–um sih–BIH–rih–cum).
