| Klassifikazzjoni xjentifika |
L-Ameridelphia huwa superordni ta' mammiferi marsupjali (l-opossumi u l-opossumi ġriedem ta' geddumhom twil). Dan qiegħed ikklassifikat fil-klassi Mammalia, fis-sottoklassi Theria, fl-infraklassi Metatheria, b' 2 ordnijiet (Paucituberculata u Didelphimorphia). Is-superordni Ameridelphia flimkien ma' l-Australidelphia jiffurmaw l-infraklassi Metatheria.
L-Ameridelphia jinkludi fiħ il-marsupjali kollha taż-2 kontinenti Amerikani, minbarra il-marsupjal kolokolo jew monito del monte Dromiciops gliroides, li għalkemm huwa mifrux mal-kontinent ta' l-Amerika ta' isfel jifforma parti mis-superordni Australidelphia.
