Donodon is an extinct genus of mammal from the Ksar Metlili Formation of Talssint, Morocco, which has been dated to the Late Jurassic to Early Cretaceous epochs ( Tithonian– Berriasian ages). The type species D. perscriptoris was described in 1991 by the palaeontologist Denise Sigogneau-Russell. A second species, D. minor, was named in 2022. [1] Donodon was a member of Cladotheria, a group that includes therian mammals ( marsupials and placentals) and some of their closest relatives. It differed from dryolestids in having upper molars that were not compressed mesiodistally. [2] Some studies have suggested that it was closely related to various South American cladotherians in the clade Meridiolestida, [3] with specific similarities to Mesungulatum, a herbivorous mesungulatid, being noted. [4] On the other hand, a 2022 phylogenetic analysis found it to be only distantly related to meridiolestidans, and instead closer to crown group therians. [1]
