Hi! Dont all the animals within Monotremata actually lay eggs? If so, then why are they classified as Theria if all Theria "...give birth to live young without using a shelled egg?" Email me at ksuttles@email.unc.edu with the answer...I am studying this for a paleontology class. —Preceding unsigned comment added by 152.23.209.219 ( talk) 19:47, 14 April 2009 (UTC)
Are these not the Eutheria? User:Wetman
Eutheria are the placental mammals. Theria includes the marsupials but not the monotremes.
Thank you, I got it now. Erase this at your pleasure ````
Added the stub flag and some context.
Note the word is also used as abbervation for Therianthrope. -- DustWolf 12:04, 10 October 2005 (UTC)

Theria are indeed the eutheria; theria are also the metatheria; thus theria include both [all of] the eutheria in addition to [all of] the metatheria.
OR, if you prefer: All eutherians (placentals) are therians; All metatherians (marsupials) are also therians; Therefore, Therians = all eutherians + all metatherians
The designation or grouping "Theria" describes what placentals and marsupials have in common with each other (namely, giving live birth to their young), and what distinguishes them both from the more primitive, egg-laying protherians. This may seem like "overclassification" to some of my fellow laypeople, but it seems to me like it is quite standard procedure among those professionals and other experts dealing with taxonomy ( classification).

Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
So far so good. But then:
Subclass: Theriiformes
Superorder: Theria
and then it lists "infraclasses". Surely infraclass is a higher taxonomic rank than superorder?
Eutheria gives Theria as being a subclass, which makes more sense, but then what is Theriiformes? -- Smjg ( talk) 20:50, 27 October 2009 (UTC)
In the taxobox, the links from infraclasses and below don't work. Dab14763 ( talk) 21:16, 1 November 2009 (UTC)
I removed this claim as the term is poorly defined and not to my knowledge really favoured in modern ecology. While the Cenozoic is often called the age of mammals, number of mammal species is vastly outnumbered by bird species, and estimates on absolute global numbers of wild mammals vs. wild birds could go either way. Either way, it didn't seem a particularly useful addition as it stood nor was it sourced or defined. Hedge89 ( talk) 13:53, 20 April 2021 (UTC)
