Theria (/ ˈ θ ɪər i ə / or / ˈ θ ɛr i ə /; from Ancient Greek θηρίον (thēríon) 'wild beast') is a subclass of mammals [2] amongst the Theriiformes.Theria includes the eutherians (including the placental mammals) and the metatherians (including the marsupials) but excludes the egg-laying monotremes and various extinct mammals evolving prior to the common ancestor of placentals ...
The term "therian" refers to people who spiritually, physically, or psychologically identify as an animal. The species of animal a therian identifies as is called a theriotype. [ 13 ] While therians mainly attribute their experiences of therianthropy to either spirituality or psychology, the way in which they consider their therian identity is ...
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.
A subclass of mammals [1] amongst the Theriiformes (the sister taxon to Yinotheria.)Theria includes the eutherians (including the placental mammals) and the metatherians (including the marsupials.)
Molecular studies by molecular systematists, based on DNA analysis, in the early 21st century have revealed new relationships among mammal families. Classification systems based on molecular studies reveal three major groups or lineages of placental mammals, Afrotheria, Xenarthra, and Boreoeutheria. which diverged from early common ancestors in the Cretaceous.
Therian may refer to: In taxonomy, a member of the mammalian subclass Theria , consisting of marsupial and placental mammals Therianthropy (disambiguation) , the mythological ability or affliction of individuals to metamorphose into animals or hybrids by means of shapeshifting
It contains modern therian mammals (marsupials and placentals) and several extinct groups, such as the "dryolestoids", amphitheriids and peramurids. The clade was named in 1975 by Malcolm McKenna . In 2002, it was defined as a node-based taxon containing "the common ancestor of dryolestids and living therians, plus all its descendants". [ 1 ]
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.
