Development and Morphology of the Dentition in the Asian Salamander, Ranodon sibiricus (Urodela: Hynobiidae)

Anna B. Vassilieva, Sergei V. Smirnov

Abstract


During ontogeny, the dentition in the hynobiid salamander Ranodon sibiricus exhibits successive series of non-pedicellate monocuspid, subpedicellate monocuspid, and pedicellate bicuspid teeth. Vomerine, premaxillary, and dentary teeth all display this ontogenetic trajectory, whereas coronoid and palatine teeth lack the pedicellate stage and maxillary teeth lack the non-pedicellate stage. Abbreviated development in the latter elements may be a consequence of the ontogenies of the corresponding bones: the coronoid and palatine are typically resorbed before the formation of the first pedicellate bicuspids, whereas the maxilla forms after the loss of the last non-pedicellate monocuspids. The palatine is rarely retained after metamorphosis, and in these instances its rudiment may bear pedicellate bicuspids. Jaw dentition is always monostichous; other dentigerous bones show a transition from mono- to bi- and tristichous teeth, which transform into monostichous following resorption of the corresponding bones. Undivided (non-pedicellate) and divided (subpedicellate and pedicellate) teeth show contrasting patterns of mineralization: the former mineralize from one center of calcification, which appears in the apex; the latter mineralize from two centers, which appear in the tooth apex and base. Similar ontogenetic differences in tooth calcification are characteristic of other salamanders and anurans and, most likely, apodans.
