Metatheria

**Metatheria** hija infraklassi ta' mammiferi marsupjali, fil-klassi Mammalia u fis-sottoklassi Theria. Il-Metatheria tiġbor fiha żewġ superordnijiet l-Australidelphia u l-Ameridelphia u seba' ordnijiet li huma id-Didelphimorphia, il-Paucituberculata, il-Microbiotheria, id-Dasyuromorphia, il-Peramelemorphia, in-Notoryctemorphia, u d-Diprotodontia. Din l-infraklassi flimkien mal-Eutheria jiffurmaw is-sottoklassi Theria.

Il-Metatheria tinkludi fiha l-ispeċij marsupjali kollha eżistenti, kemm dawk estinti kif ukoll dawk estanti.
