Discussion of Phylogenetic Relationships
The name Salientia generally has referred to †Triadobatrachus + Anura (Milner, 1988). Ford and Cannatella (1993) defined it as a stem-based name for amphibians that are more closely related to Anura than to Caudata or Gymnophiona. Synapomorphies that unite all of the currently known taxa in Salientia include 14 presacral vertebrae, elongate and anteriorly directed ilium, presence of a frontoparietal, and a toothless dentary (Milner, 1988). To these, Trueb and Cloutier (1991) added the absence of a lacrimal and unicapitate ribs as other unique synapomorphies, and four other synapomorphies that showed homoplasy among closely related dissorophoid temnospondyls.
