The elasmotherium’s 33-inch-long skull has a huge bony protuberance on the frontal bone consistent with the support structure for a massive horn.4 In fact, archaeologist Austen Henry Layard, in his 1849 book Nineveh and Its Remains, sketched a single-horned creature from an obelisk in company with two-horned bovine animals; he identified the single-horned animal as an Indian rhinoceros.5 The biblical unicorn could have been the elasmotherium.6
