Specimen: Rendering of Siberian unicorn (Elasmotherium sibiricum)
Description: An extinct species of rhinoceros that is verified to have lived in the region of Kozhamzhar in modern Kazakhstan until at least 300,000 years ago. Its large size and distinct horn made its appearance like unicorns of human legend.


Specimen: Fossilized skull resembling Siberian unicorn
Description: This skull fragment has traits that suggest it could belong to a Siberian unicorn. However, carbon dating suggests that it is only 29,000 years old.

Publication issues: One issue with the study of this fossil is that it was published in the American Journal of Applied Sciences, an online open access journal published by the company Science Publications (http://thescipub.com/). Open access journals have been criticized in academia for often accepting articles with little or no formal peer review. They have a reputation for charging their writers large amounts of money in order to publish in them, and tend to use a sham peer review process if one even exists. They are often used by academics who lack other outlets for publishing their work, typically because it is of poor quality to merit publication in a serious academic journal. These academics can then claim that they have been published, which is vital for getting tenure and promotion. Science Publications was listed on the most recent edition of the now deleted "Beall's List" of potential, possible, or probable predatory scholarly open access publishers. However, disreputable academic journals have influence on the media and even some institutions. Besides the above Tweet, this article was picked up by something even better than the royal society: news sources such as CNN, Huffington Post, The Guardian, and Fox News.
Did humans and unicorns really live together?: It is certainly possible, but without further verification and study of the results and publication in more reputable journals, it is difficult to say whether the Siberian unicorn had not already been extinct 30,000 years ago. However, in the meantime we can speculate about what other species the skull might belong to. Perhaps unicorns whose horns had magical powers really did roam Siberia.
