Description
Not much is known about the appearance of Alphadon, as it is only known from teeth. It probably grew to about 12 in (30 cm) and may have resembled a modern opossum. Judging from its teeth, it was likely an omnivore, feeding on fruits, invertebrates and possibly small vertebrates.
Taxonomy and classification
The type species is Alphadon marshi. Eight other species are known.
The species Alphadon jasoni was originally described by Storer (1991); it was subsequently transferred to the herpetotheriid genus Nortedelphys.
Recent phylogenetic studies group it with other northern non-marsupial metatherians such as Albertatherium and Turgidodon. A 2016 phylogenetic analysis is shown below.
