Once called simply "tail spikes" or ''osteoderms'' scientifically, the word ''thagomizer'' had its origins as a mere joke. In 1982 cartoonist [[Gary Larson]] published a panel from his ''[[Far Side]]'' series of comic strips, which showed a lecture hall of caveman scientists, one of which was pointing out the feature of the stegosaur responsible for the demise of "the late Thag Simmons". In fact, so popular was the panel with scientists that the term ''thagomizer'' was adopted as an actual anatomical term for the Stegosaurus tail-spike arrangment. | Once called simply "tail spikes" or ''osteoderms'' scientifically, the word ''thagomizer'' had its origins as a mere joke.
