The 23 pages that link to Placentalia, each with the reason it gives.

• MammalCompared with: Placental mammals represent the dominant reproductive pattern among living mammal species.

• MarsupialCompared with: Its longer prenatal development contrasts with the typical marsupial pattern.

• MammaliaCompared with: Placental mammals represent one major reproductive branch within Mammalia.

• ViviparityBroader topic: They are the most familiar example of viviparity with extensive maternal-fetal exchange.

• Mammary glandCompared with: Placental mammals typically nurse offspring after a longer prenatal period than marsupials.

• PrimateRelated: Most primates belong to this major group of living mammals.

• Evolution of mammalsBroader topic: Placental mammals became the most species-rich living mammal group.

• AfrotheriaNarrower topic: Afrotheria is one of the deepest branches within placental mammals.

• XenarthraNarrower topic: Xenarthra is one major branch within this broader mammal group.

• DiprotodontiaCompared with: Placental mammals provide a reproductive contrast to the marsupial members of Diprotodontia.

• EutheriaBroader topic: Living members of Eutheria belong to this group, though the clade also includes extinct relatives.

• MetatheriaCompared with: Placental mammals belong to the sister lineage often contrasted with metatherians.

• EomaiaCompared with: Eomaia predates crown placentals and is not evidence that modern placental orders already existed.

• EulipotyphlaNarrower topic: Eulipotyphla is one order within this broader mammalian group.

• OxyaenidaeNarrower topic: Oxyaenidae belongs to the placental mammal lineage.

• DasyuromorphiaCompared with: Placental mammals differ from marsupials in reproductive development and include many ecological counterparts.

• HyaenodontaNarrower topic: Hyaenodonts belonged to the placental mammal radiation.

• PantodontaNarrower topic: Pantodonts are generally placed among early placental mammals.

• SparassodontaCompared with: Placental predators later entered South America and occupied some similar ecological roles.

• LitopternaNarrower topic: Litopterns belonged to the placental mammal radiation that diversified after the end-Cretaceous extinction.

• TreeshrewNarrower topic: Treeshrews are placental mammals, a broader group than their distinctive order.

• ErinaceidaeNarrower topic: Hedgehogs and moonrats are placental mammals, rather than marsupials or monotremes.

• TaeniodontaNarrower topic: Taeniodonts are classified among placental mammals.
