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.
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 ...
The latter subclass is divided into two infraclasses: pouched mammals (metatherians or marsupials), and placental mammals (eutherians, for which see List of placental mammals). Classification updated from Wilson and Reeder's "Mammal Species of the World: A Taxonomic and Geographic Reference" using the "Planet Mammifères" website. [1]
Marsupials are a diverse group of mammals belonging to the infraclass Marsupialia.They are natively found in Australasia, Wallacea, and the Americas.One of the defining features of marsupials is their unique reproductive strategy, where the young are born in a relatively undeveloped state and then nurtured within a pouch on their mother's abdomen.
Eutheria (from Greek εὐ-, eú-'good, right' and θηρίον, thēríon 'beast'; lit. ' true beasts '), also called Pan-Placentalia, is the clade consisting of placentals and all therian mammals that are more closely related to placentals than to marsupials.
