Laurasiatheria (/ l ɔː r ˌ eɪ ʒ ə ˈ θ ɪər i ə,-θ ɛr i ə /; "Laurasian beasts") is a superorder of placental mammals that groups together true insectivores (eulipotyphlans), bats (chiropterans), carnivorans, pangolins (), even-toed ungulates (artiodactyls), odd-toed ungulates (perissodactyls), and all their extinct relatives.
Boreoeutheria (/ b oʊ ˌ r iː oʊ j uː ˈ θ ɛr i ə /, "northern eutherians") is a magnorder of placental mammals that groups together superorders Euarchontoglires and Laurasiatheria. [ 1 ] [ 2 ] [ 5 ] The clade includes species as diverse as giraffes , pigs , zebras , rhinos , dogs , cats , rabbits , mice , squirrels , bats , whales ...
The class Mammalia is divided into two subclasses based on reproductive techniques: monotremes, which lay eggs, and therians, mammals which give live birth, which has two infraclasses: marsupials/metatherians and placentals/eutherians. See List of monotremes and marsupials, and for the clades and families, see Mammal classification ...
In 1997, the classification of mammals was revised by Malcolm C. McKenna and Susan K. Bell. [10] The Classification of Mammals Above the species level, here referred to as the "McKenna/Bell classification", is a comprehensive work on the systematics, relationships, and occurrences of all mammal taxa, living and extinct, down through the rank of ...
Cetartiodactyla is a large order of hoofed mammals, the even-toed ungulates, and aquatic mammals, cetaceans. Cetacea was found to be nested within "Artiodactlya" and has now been moved into that order, whose name is now Cetartiodactyla. [2] Even-toed ungulates are found nearly world-wide, although no species are native to Australia or Antarctica.
Bats are flying mammals of the order Chiroptera (/ k aɪ ˈ r ɒ p t ər ə /). [ a ] With their forelimbs adapted as wings , they are the only mammals capable of true and sustained flight . Bats are more agile in flight than most birds, flying with their very long spread-out digits covered with a thin membrane or patagium .
Placental mammals (infraclass Placentalia / p l æ s ə n ˈ t eɪ l i ə /) are one of the three extant subdivisions of the class Mammalia, the other two being Monotremata and Marsupialia. Placentalia contains the vast majority of extant mammals, which are partly distinguished from monotremes and marsupials in that the fetus is carried in the ...
Scrotifera ("scrotum bearers") is a clade of placental mammals that groups together grandorder Ferungulata, Chiroptera (bats), other extinct members and their common ancestors. The clade Scrotifera is a sister group to the order Eulipotyphla (true insectivores) based on evidence from molecular phylogenetics , [ 1 ] and together they make ...
