Rogue taxidermy is a multi-media sculptural form which uses some of techniques of true taxidermy and often references the style of trophy or museum taxidermy. It does not necessarily use preserved animals and may be enitely artificial. Some modern instances are exhibited as artworks.
However, the practice is an old one, dating back as far as the construction of fantastic animals as the centrepieces of medieval banquets.
Later it became a standard practice of showmen. The Fiji Mermaid was one such piece, credited to P T Barnum, as was the 'Jackalope'. Other examples are the 'chupacabra' and Kap-Dwa, the 'Two-Headed Patagonian Giant'.
