There is something wrong here.
Placentalia=Eutheria (although Placentalia is something more inclusive). Why is Desmostylia listed while other extinct orders are not? Ucucha 17:26, 9 Apr 2005 (UTC)
To be checked
Meridiungulata - Incertae sedis
there is no direct link from placentalia to Superordo: Cetartiodactyla. One has to go to Ceatean and then back up to Cetartiodactyla. You should be able to go from placentalia to Superorder Cetartiodactyla
