Theriiformes is a clade of mammals. The term was coined by Timothy B. Rowe in his doctoral dissertation,[1] 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).[2] Mammals more closely related to therians than to multituberculates are included in the clade Trechnotheria.[3] 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.[4]
