Monotremes and marsupials are both orders within the classification of marsupials.Because monotremes and marsupials are mammals, they are warm-blooded vertebrates with skin, fur or hair, and breathe using lungs.Monotremes and marsupials, along with placental mammals, feed their young on mothers' milk.Monotremes and marsupials are both found primarily (but not exclusively) on the Australian continent.

Skin.
Monotremes lay eggs, as do reptiles. Monotremes' limbs go outward (rather than downward) from their main body, which is also true for reptiles. Monotremes lack a corpus callosum (which placental mammals have), as do reptiles. Monotremes and reptiles both have cloacas, while placental mammals have separate openings for urination and defecation. This evidence all shows monotremes to be a link between reptiles and mammals, but we now think that monotremes just evolved from an earlier branching from the mammalian tree of lineage than the marsupials and placental mammals evolved from. Monotremes are not a link between reptiles and mammals.
