Newly described marsupial specimens of Judithian (late Campanian) and Lancian (Maastrichtian) age in the western interior of North America (Wyoming to Alberta) have dental morphologies consistent with those expected in ...

Tetrapods have flexor tendons in the palmar surface of the manus that transmitforces generated by superficial and deep forearm muscles to the digits. Two patterns (“P”and “L”) of tendinous connections among the deep layer ...

Extant marsupials are highly diverse, both morphologically and ecologically. As a key ecological factor, diet has been studied in marsupials at the species level. However, a general lack of phylogenetic integration has ...

The honey possum is the only non-volant mammal to feed exclusively on a diet of nectar and pollen. Like other mammalian and avian nectarivores, previous studies indicated that the honey possum's basal metabolic rate was ...

Systematic revisions of South American marsupials have contributed to our knowledge about genus and species diversity in the last decades, including studies of the most recently described genus Cryptonanus (Didelphidae), ...

Most extant New World marsupials belong in the Didelphidae, which comprises ca. 110 currently recognized species of opossums. Didelphids are small mammals with their mean body mass, at species level, ranging from ca. 7 g ...

In this study I provide a phylogenetic hypothesis for didelphid Marsupials including a suite of 114 postcranial characters. The postcranial evidence was cladistically analyzed separately and concatenated with a nonmolecular ...
