Although some believed that the armor resembled that of the modern armadillo, the popular opinion was the Megatherium theory. It was not until Professor E. D’Alton wrote a memoir to the Berlin Academy in 1833 comparing the extreme similarities of these mysterious fossils to that of the armadillo, that the scientific world seriously considered that the pieces of carapaces and fragments of bone could belong to some prehistoric version of Dasypus. D’Alton said that "all the peculiarities of the former [Dasypus] may be paralleled to the latter [fossil pieces]" He concluded that the fossils belonged to some prehistoric version of an armadillo. However, since a full skeleton was not available at the time, he said that his idea was not conclusive. This uncertainty in the fossil remains continued until a man named Dr. Lund identified the remains as a new genus in his 1837 memoir.
When scholars first acknowledged the genus Glyptodon, there was not a consensus on its name. In 1837 Dr. Lund, a professor who wrote a memoir on Brazil’s ancient fauna, suggested these creatures be recognized as the new genus "Hoplophorus". In 1838, another scientist, Professor Bronn, published in the second edition of his book Lethaea Geognostica a proposal for the new genus to be called "Chlamydotherium". In Professor D’Alton’s 1839 memoir, it was called "Pachypus". The director at the Museum of Natural History in Dijon at the time, M.L. Nodot, had named the genus "Schistopleuron".
It was finally given a single name when English scholar
After unifying the name of this genus, Owen continued working on its taxonomy. In 1845, after analyzing the fossils of his colleagues, he named four species within the genus: G. clavipes, G. reticulatus, G. ornatus, and G. tuberculatus.
