With almost 4800 extinct and extant genera, including 1135 extant (living) genera and over 5000 extant species arrayed in 20 extant orders, placentals (extant eutherians) are the most taxonomically diverse of the three branches of extant mammals. Some functions of … Eutheria They are distinguished from non-eutherians by various features of the feet, ankles, jaws and teeth. Order Dermoptera(2species) Order Chiroptera(928species) Order Carnivora(271species) Order Insectivora(429species) Order Artiodactyla(220species) Order Cetacea(78species) Order Tubulidentata(1species) Order Perissodactyla(18species) Order Hyracoidea(6species) Order Proboscidea(2species) Order Sirenia(5species) Eutheria (Placental Mammals) This list should help guide you to particular groups of interest. Spec's eutherians are much less diverse than those of our home timeline, although even in Spec, the "true beasts" make up more than two thirds of the planet's mammalian species. Other orders are made up of only one sort of creature; Order Chiroptera, or example, consists of 18 families of bats. The Latin names of the orders of mammals given here are followed by their common names and the families that make up each order. The order of mammals without which no TV nature documentary would be complete, carnivores are divided into two broad categories: feliforms and caniforms. ‘Previous paleontological and molecular evidence has indicated that cetaceans and artiodactyls constitute a natural clade within the subclass Eutheria.’ ‘They either sequenced this fragment or obtained published sequences for a wide variety of mammals, covering almost all traditional orders of the Eutheria.’ Eutheria includes one of three major clades of mammals, the extant members of which are referred to as placentals. The placental mammals include such diverse forms as whales, elephants, shrews, and armadillos. They are also some of the most familiar organisms to us, including pets such as dogs and cats, as well as many farm and work animals, such as sheep, cattle, and horses. Feliforms include not only obvious felines (like lions, tigers, cheetahs, and house cats), but also hyenas, civets, and mongooses. The taxa are given in the order in which they are considered. Start studying Eutheria Overview. Examples of the various types of animals included in each family also are given. Eutheria (/ j uː ˈ θ ɪər i ə /; from Greek εὐ-, eu-"good" or "right" 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.All placental mammals are eutherians. mammals.

The full classification is given in the three lists in the menu indicated by Classification 1, Classification 2, and Classification 3. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Placental mammals are a rather diverse group, with nearly 4000 described species, mostly rodents and bats (photos at left). Eutheria, mammals that carry their young in the womb until fully developed, are the most familiar of the mammalian groups - a fact that is not surprising, since this is the group to which humans belong. One of the major differences between placental and non-placental eutherians is that placentals lack the epipubic bones, which are present in all other fossil and living mammals.
