Rauisuchidae
Rauisuchidae is a group of large (up to or more) predatory Triassic archosaurs. There is some disagreement over which genera should be included in Rauisuchidae and which should be in the related Prestosuchidae and Poposauridae, and indeed whether these should even be thought of as separate valid families. Rauisuchids occurred throughout much of the Triassic, and may have first occurred in the Early Triassic if some archosaurian taxa such as "Scythosuchus" and "Tsylmosuchus" are considered to be within the family.

An early cladistic analysis of crocodylotarsan (pseudosuchian) archosaurs included "Lotosaurus", "Fasolasuchus", "Rauisuchus", and "the Kupferzell rauisuchid" (later called "Batrachotomus") within Rauisuchidae. However, a later study found that "Batrachotomus" was a more basal pseudosuchian only slightly more "advanced" than "Prestosuchus". In addition, the toothless "Lotosaurus" has been found to be more closely related to the Ctenosauriscidae, a clade of poposauroids with sails on their backs.

Two genera previously classified as poposaurids, are in fact rauisuchids. These include "Teratosaurus" and "Postosuchus".
