Alphadon (meaning “first tooth”) was a genus of small, primitive metatherians, a group of mamals that include modern-day marsupials. Being only known from teeth, not much is known about its physiological appearance; however it is suspected to have grown to a length of 12 in (30 cm) and presumably resembled the modern opossum. The aforementioned teeth hint at a likely-omnivorous diet, and it is believed that it must have fed upon fruits, invertebrates and potentially small vertebrates.

It lived during the end of the late Cretaceous period, alongside dinosaurs such as Tyrannosaurus and Triceratops. They were distributed across North America, ranging from as far north as Alberta, Canada to as far south as New Mexico. When the marsupial numbers began to plummet at the end of the Cretaceous, Alpahadon would become one of only two surviving representatives, with the other being its Paleocene successor Peradectes.
