Amphilestes is a genus of extinct triconodont mammal from the Middle Jurassic

It is known from various dental and mandibular remains. These were discovered in the shale fields of Oxfordshire in the United Kingdom.^[1]

The dental formula of the mandible is 4:1:4:5.

The premolars are symmetrical and the crowns look like tricusped molars, with the central cusp being largest in premolars and molars, though the size difference is less great in the premolars.
