[3] Judging from its teeth, it was likely an omnivore, feeding on fruits, invertebrates and possibly small vertebrates.

Alphadon had a very good sense of smell and sight to track down its food, both during the day and night.

[2] The species Alphadon jasoni was originally described by Storer (1991);[5] it was subsequently transferred to the herpetotheriid genus Nortedelphys.

[6] Recent phylogenetic studies group it with other northern non-marsupial metatherians such as Albertatherium and Turgidodon.
