    • n glyptodon The typical and best-known genus of the family Glyptodontidæ; the long-tailed fossil armadillos or glyptodons, with 5 toes on the hind feet and 4 on the fore, the fifth digit of which is wanting. Species are G. clavipes and G. reticulatus, from the Pleistocene of South America.
    • n glyptodon [lowercase] An animal of the family Glyptodontidæ) or Hoplophoridæ; one of the gigantic fossil armadillos of South America. They are all distinguished from the living armadillos not only by their superior size, but by having the carapace composed of a single solid piece without movable segments, and also by possessing a ventral shield or plastron. The superficial resemblance to tortoises is striking; the feet are like those of some turtles, and, as in chelonians, the head could be withdrawn into the shell, though the rest of the vertebral column is a solid tube. The genera are several and the species rather numerous.
