Achyrodon is an extinct genus of mammal from the Berriasian epoch of Early Cretaceous southern England . The taxon was first described by Richard Owen in 1871 for teeth from the Lulworth Formation.[1] The taxon has been considered a synonym of co-existing Amblotherium pusillum, but can be distinguished by differences in the dental anatomy and an overall smaller size. Achyrodon was closely related to co-existing genus Phascolestes and the slightly younger European form Crusafontia, and together they make up the subfamily Kurtodontinae within Dryolestidae, a family of early mammals between modern monotremes and therians with no living descendants.[2]
