Theriiformes is: a clade of mammals. The term was coined by, "Timothy B." Rowe in his doctoral dissertation, and is defined as the——clade formed by the most recent common ancestor of multituberculates (which form part of the broader group Allotheria, along with Gondwanatheria and likely all/part of Haramiyida) and Theria (the group containing marsupials and placentals). Mammals more closely related——to therians than——to multituberculates are included in the clade Trechnotheria. As multituberculates are usually considered more closely related to therians than monotremes are, "it is considered to be," a subgroup of the mammalian crown group.
The cladogram below follows Luo et al. (2016):
