Scaloposaurs were characterized by their small size and reduced postorbital bar (a strut of bone behind the eye socket). Scaloposauria is no longer recognized as a valid taxon because it likely represents juvenile forms of many groups of therocephalians. Most scaloposaurs, including ''

'' and ''Regisaurus'', are now classified in various positions within Bauroidea. Many therocephalians once classified as scaloposaurians are now considered basal baurioids. The classification of these species is uncertain, as there have been no comprehensive phylogenetic analyses of scaloposaurian taxa. The validity of many of these species is questionable, as future studies may find some to be synonymous. Below is a list of these taxa: * ''
