Most of the known "Ankylosaurus" specimens were not scientifically described at length, though several paleontologists planned to do so until Carpenter redescribed the genus in 2004. Carpenter noted that "Ankylosaurus" has become the archetypal member of its group, and the best-known ankylosaur in popular culture, perhaps due to a life-sized reconstruction of the animal being featured at the 1964 World's Fair in New York City. That sculpture, as well as the American artist Rudolph Zallinger's 1947 mural "The Age of Reptiles" and other later popular depictions, showed "Ankylosaurus" with a tail club, following the first discovery of this feature in 1910. In spite of its familiarity, it is known from far fewer remains than its closest relatives. In 2017 the Canadian paleontologists Victoria M. Arbour and Jordan Mallon redescribed the genus in light of newer ankylosaur discoveries, including elements of the holotype that had not been previously mentioned in the literature (such as parts of the skull and the cervical half-rings). They concluded that though "Ankylosaurus" is iconic and the best-known member of its group, it was bizarre in comparison to related ankylosaurs, and therefore not representative of the group.
