Euungulata is a proposed clade

Clade

A clade is a group consisting of a species and all its descendants. In the terms of biological systematics, a clade is a single "branch" on the "tree of life". The idea that such a "natural group" of organisms should be grouped together and given a taxonomic name is central to biological...

Order (biology)

In scientific classification used in biology, the order is# a taxonomic rank used in the classification of organisms. Other well-known ranks are life, domain, kingdom, phylum, class, family, genus, and species, with order fitting in between class and family...

• Perissodactyla
• Cetacea
  Cetacea
  The order Cetacea includes the marine mammals commonly known as whales, dolphins, and porpoises. Cetus is Latin and is used in biological names to mean "whale"; its original meaning, "large sea animal", was more general. It comes from Ancient Greek , meaning "whale" or "any huge fish or sea...
  
  
• Artiodactyla

It is based on evidence from molecular phylogenetics. Within Euungulata, Cetacea and Artiodactyla form the clade

 Cetartiodactyla

Cetartiodactyla

Cetartiodactyla is the clade in which whales and even-toed ungulates have currently been placed. The term was coined by merging the name for the two orders, Cetacea and Artiodactyla, into a single word. The term Cetartiodactyla reflects the idea that whales evolved within the artiodactyls...

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

Zooamata

Zooamata is a proposed clade of mammals consisting of Ferae and Perissodactyla . Together with Cetartiodactyla and chiroptera it forms Scrotifera , and is part of Laurasiatheria...
