(''Pleistocene Vertebrates from Celebes. IV. - Archidiskodon celebensis nov spec.'' ) Zoologische Mededelingen, Museum Leiden 30: 205–226.〕 The most evident difference with the latter is the presence of functional lower tusks in some individuals. This was considered as paedomorphosis, a retention of juvenile characters in the adult stage, by Vincent Maglio in his revision of the proboscideans in 1973.〔Maglio, V.J. (1973). ''Origin and evolution of the Elephantidae''. Transactions of the American Philosophical Society Philadelphia Volume 63. American Philosophical Society, Philadelphia. Pp. 149〕 He based his conclusion on the presence of vestigial incisive germs in mandibles of ''Mammuthus planifrons''. This idea was followed by Hooijer in 1974.〔Hooijer, D.A. (1974). (''Elephas celebensis'' (Hooijer) from the Pleistocene of Java'' ).
