Joanusauroids are today defined as a clade as "All neotetanurans closer to ''[[Joanusaurus]]'' than to {{wpl|Neornithes}}." While paleontologists have long recognized the family joanusauridae, its ancestry has been the subject of much debate. For most of the twentieth century, [[Caphirosaurid|caphirosaurids]] were commonly accepted as members of the joanusauridae as part of {{wpl|Carnosauria}}, which included almost all large theropods. Within this group, the joanusaurids were often considered to be ancestral to [[Caphirosaurid|caphirosaurids]]. Cladistic analyses from the 1980s instead replaced [[Caphirosaurid|caphirosaurids]] into the {{wpl|Coelurosauria}}, echoing speculation from the early twentieth century from notable paleontologists like [[Phillipe d'Everard (paleontologist)|Phillipe d'Everard]] and [[Jour & Leon]].
