Euungulata

Euungulata ("true ungulates") is a proposed clade of mammals within Laurasiatheria, consisting of the following orders and their common ancestors:

It is based on evidence from molecular phylogenetics.[1][2] Within Euungulata, Cetacea and Artiodactyla form the clade Cetartiodactyla.

   Laurasiatheria   

 Eulipotyphla

   Scrotifera   

 Chiroptera

   Fereuungulata   
   Ferae   

 Pholidota


 Carnivora


   Euungulata   

 Perissodactyla    


 Cetartiodactyla





There is still uncertainty regarding the placement of Perissodactyla within the overall Laurasiatheria tree; an alternate grouping of Perissodactyla with Ferae has been proposed as the clade Zooamata.
