Metatheria
Metatheria is a mammalian clade that includes all mammals more closely related to marsupials than to placentals. First proposed by Thomas Henry Huxley in 1880, it is a more inclusive group than the marsupials; it contains all marsupials as well as many extinct non-marsupial relatives. It is one of two groups placed in the clade Theria alongside Eutheria, which contains the placentals. Remains of metatherians have been found on all of Earth's continents.
Pinheirodontidae
Pinheirodontidae is a poorly known family of fossil mammals which belong to the informal suborder "Plagiaulacida" within the order Multituberculata. Remains are known from the Late Jurassic to Early Cretaceous of Europe (predominantly Portugal and Spain), but are so far restricted to isolated teeth, as well as a single lower jaw. The family Pinheirodontidae was named by Hahn G. and Hahn R. in 1999, after the locality of Porto Dinheiro, in central west Portugal.
Astroconodon
Astroconodon is an extinct genus of mammal from the Cretaceous of North America. Part of Eutriconodonta, it was a small sized predator, either a terrestrial insectivore and carnivore, or a semi-aquatic piscivore.
