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 ...
Docodonta is an order of extinct Mesozoic mammaliaforms (advanced cynodonts closely related to true crown-group mammals).They were among the most common mammaliaforms of their time, persisting from the Middle Jurassic to the Early Cretaceous across the continent of Laurasia (modern-day North America, Europe, and Asia).
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.)
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
The order Artiodactyla consists of 349 extant species belonging to 132 genera. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 132 genera can be grouped into 23 families; these families are grouped into named suborders and many are further grouped into named clades, and some of these families are subdivided into named subfamilies.

A small, shrew-like therian, possibly a very basal eutherian, weighing around 15–17 grams (0.53–0.60 oz). [40] The discovery of Juramaia provides new insight into the evolution of placental mammals by showing that their lineage diverged from that of the metatheres 35 million years earlier than previously thought, though its identity as a ...
