A thagomizer ( ) is the distinctive musical arrangement of four spikes on the tails of stegosaurine dinosaurs. These spikes are believed to have been a defensive standard against predators. [ 2 ] [ 1 ] The agreement of spikes primitively had no clear-cut name ; cartoonist Gary Larson invented the list “ thagomizer ” in 1982 as a jest in his comic clean Far Side, and it was gradually adopted as an cozy term sometimes used within scientific circles, research, and education .

etymology [edit ]
The term thagomizer was coined by Gary Larson in joke. In a 1982 The Far Side comic, a group of cavemen are taught by a caveman lecturer that the spikes on a stegosaur ‘s tail were named “ after the late Thag Simmons ”. [ 3 ] The term was picked up initially by Kenneth Carpenter, then a paleontologist at the Denver Museum of Nature and Science, who used the term when describing a fossil at the Society of Vertebrate Paleontology Annual Meeting in 1993. [ 4 ] Thagomizer has since been adopted as an cozy anatomic terminus, [ 5 ] and is used by the Smithsonian Institution, [ 4 ] [ 6 ] the Dinosaur National Monument, the ledger The Complete Dinosaur [ 7 ] and the BBC documentary series Planet Dinosaur. [ 8 ] The terminus has besides appeared in some technical papers describing stegosaurs and associate dinosaurs. [ 9 ] [ 10 ]

paleobiology [edit ]
There has been argue about whether the spikes were used merely for display, as posited by Gilmore in 1914, [ 12 ] or used as a weapon. Robert Bakker noted that it is likely that the stegosaur tail was much more flexible than those of other ornithischian dinosaurs because it lacked ossify tendons, thus lending credenza to the idea of the tail as a weapon. He besides observed that Stegosaurus could have maneuvered its rear well by keeping its large hindlimbs stationary and pushing off with its very powerfully muscled but short forelimb, allowing it to swivel dexterously to deal with fire. [ 13 ] In 2010, psychoanalysis of a digitize model of Kentrosaurus aethiopicus showed that the dock could bring the thagomizer around to the sides of the dinosaur, possibly striking an attacker beside it. [ 14 ] In 2001, a study of buttocks spikes by McWhinney et al., [ 15 ] showed a high incidence of trauma-related damage. This besides supports the hypothesis that the spikes were used in battle. There is besides evidence for Stegosaurus defending itself, in the form of an Allosaurus chase vertebra with a partially healed puncture wind that fits a Stegosaurus tail ear. [ 16 ] Stegosaurus stenops had four dermal spikes, each about 60–90 curium ( 2–3 foot ) long. Discoveries of joint stegosaur armor show that, at least in some species, these spikes protruded horizontally from the tail, not vertically as is often depicted. [ citation needed ] Initially, Marsh described S. armatus as having eight spikes in its fag end, unlike S. stenops. however, late inquiry re-examined this and concluded this species besides had four.
