Dental anomalies are described after analyzing series of skulls and mandibles of three species of South American marsupials: the monito del monte {Dromiciops gliroides), the silky shrew-opossum {Caenolestes fuliginosus) and the Chilean shrew-opossum {Rhyncholestes raphanurus). The anomalies are classified into three categories: (1) supernumerary or missing teeth in normal positions of the dental series, (2) morphological anomalies like teeth fusion or anomalous crown shape, and (3) presence of teeth in unusual positions. Cusp fusion and supernumerary teeth at the end of the toothrow have been observed predominantly in D. gliroides. A tendency to find supernumerary or missing teeth is observed between the procumbent incisors and the second l...
