This class gave rise to Multituberculata ( herbivorous mammals ), Triconodonta and Symmetrodonta ( carnivorous and insectivorous mammals ).
2.
It is named for the three tubercles ( cusps ) of the molar teeth ( not to be confused with Triconodonta ).
3.
:: I mostly agree, however, I don't think that Allotheria and Triconodonta are Theriiformes ( multis may have been given birth to live young, but that's probably convergent evolution ).
4.
First described in 1859 by Richard Owen, it is the type genus for the order "'Triconodonta "', a group of mammals characterised by their three-cusped ( triconodont ) molar teeth.
5.
These characters appeared to unite monotremes with a range of Mesozoic fossil orders ( Morganucodonta, Triconodonta, Docodonta and Multituberculata ) in a broader clade for which the name Prototheria was retained, and of which monotremes were thought to be only the last surviving branch ( Benton 2005 : 300, 306 ).
6.
"Triconodonta " had long been used as the name for an order of early mammals which were close relatives of the ancestors of all present-day mammals, characterized by molar teeth with three main cusps on a crown that were arranged in a row . but was later expanded to include other taxa such as " Morganucodon " or " Sinoconodon ".
