Hundreds of years ago, a hodgepodge of incomplete animal skeletons were arranged together into what is now called the "Magdeburg Unicorn". This bizarre beast is made from a rhino skull, mammoth legs, and a narwhal horn. At the time, the people who assembled it thought all the bones were from one creature.
