Dryolestidae
Dryolestidae was a widespread family of Mesozoic mammals. The clade is not based on a phylogenetic definition, but instead on the possession of unequal roots for the molars of the lower jaw. Additionally, the clade is distinguished by hypsodonty in lower molars, and uneven labio-lingual height for the alveolar borders of the dentary.[1]
