<h2>Eutheria</h2>

<p>
Eutheria (/juːˈθɪəriə/; from Greek εὐ-, eu- "true/good" and θηρίον, thēríon "beast" hence "true beasts") is one of two mammalian clades with extant 
members that diverged in the Early Cretaceous or perhaps the Late Jurassic. The other is the Metatheria, which includes marsupials, most of whom 
accommodate their neonates in pouches. Except for the Virginia opossum, which is a metatherian, all mammals indigenous to Europe, Africa, Asia, 
and North America north of Mexico are eutherians. Extant eutherians, their last common ancestor, and all extinct descendants of that ancestor are placentals, in the group Placentalia.

Eutherians are distinguished from noneutherians by various features of the feet, ankles, jaws and teeth. One of the major differences between 
placental and nonplacental eutherians is that placentals lack epipubic bones, which are present in all other fossil and living mammals (marsupials and monotremes).

The oldest known eutherian species is Juramaia sinensis, dated at 160 million years ago from the Jurassic in China.

The name "Eutheria" was introduced by Thomas Henry Huxley in 1880, meant to encompass a more broadly defined group than Placentalia.
