Placental mammals (infraclass Placentalia /plæsənˈteɪliə/) are one of the three extant subdivisions of the class Mammalia, the other two being Monotremata and Marsupialia. (wikipedia.org)
Placentalia mostly only if the crown group is meant) form, like the egg-laying monotons (Protheria) and the marsupials (Metatheria), a subclass of mammals (Mammalia). (zxc.wiki)
Mammals1
Placentalia contains the vast majority of extant mammals, which are partly distinguished from monotremes and marsupials in that the fetus is carried in the uterus of its mother to a relatively late stage of development. (wikipedia.org)
Theria1
Yn 'e measte yndielings wurde al dy soarten ferdield yn twa grutte subgroepen: de (aaien lizzende) oersûchdieren ( Prototheria ), mei net mear as fiif libbene soarten fûgelbekdieren en eamelychels , en de moderne sûchdieren ( Theria ), dêr't alle oare soarten ûnder falle. (wikipedia.org)

Marsupialia1
Dêrby kin dy lêste groep dan noch wer fierder ferdield wurde yn 'e wichtige subgroepen fan 'e bûdeldieren ( Marsupialia ) en de plasintadieren ( Placentalia ). (wikipedia.org)
