- Hans-Dieter Sues and Philippe Taquet described the new genus and species Majungatholus atopus.[5]
- Alan Jack Charig rejected the validity of the Ceratosauria and Ceratosauridae.[2]
1980s
1980
- José Bonaparte and Jaime Powell described the new genus and species Noasaurus leali.[5] They classified it in a new family, the Noasauridae.[2]
1985
- Bonaparte and Fernando Emilio Novas described the new genus and species Abelisaurus comahuensis.[5]
- Bonaparte described the new genus and species Carnotaurus sastrei.[5]
1986
- Robert T. Bakker thought the loose joints in the skull of Ceratosaurus was an adaptation allowing it to swallow prey that would otherwise be too large.[6]
- Ricardo Martínez and others described the new genus and species Xenotarsosaurus bonapartei.[5]
- Gauthier "resurrected the name Ceratosauria" to apply to the sister group of the tetanuran theropods. However, while he listed the members of his Ceratosauria, he did not propose a formal phylogenetic definition.[2]
1989
- Rowe formally defined the Ceratosauria as theropods more closely related to Ceratosaurus nasicornis than birds, based on Gauthier's 1986 usage of the term.[2]
1990s
1990
- Rowe and Gauthier published a node-based definition of Ceratosauria.[2]
1991
- Jean Le Loeuff and Eric Buffetaut described the new genus and species Tarascosaurus salluvicus.[3]
- Bonaparte described the new genus and species Velocisaurus unicus.[5]
- Novas regarded the Ceratosauria as consisting of two sister groups, the Coelophysoidea and their sister group, the Neoceratosauria.[2]
1994
- Thomas Holtz named the Coelophysoidea, then thought to be ceratosaurs. He defined them as all theropods more closely related to Coelophysis than to Ceratosaurus. Holtz defined the Neoceratosauria as all theropods closer to Ceratosaurus than to Coelophysis. He also defined the ceratosaur subclade Abelisauroidea as all theropods closer to Carnotaurus sastrei than to Ceratosaurus nasicornis.[2]
1995
- Hugues Accarie and others described the new genus and species Genusaurus sisteronis.[5]
1996
- Bonaparte described the new genus and species Ligabueino andesi.[3]
- Sankar Chatterjee and Dhiraj Kumar Rudra observed that abelisaur teeth had lower crowns than other carnivorous dinosaurs either within or outside of Ceratosauria.[6]
1998
- Coria and Leonardo Salgado described the new genus and species Ilokelesia aguagrandensis.[5]
- Sereno redefined Ceratosauria as all neotheropods closer to Coelophysis bauri than to birds. However, this definition never received broad acceptance by the scientific community because the Rowe had already defined the group in 1989, and therefore had priority.[2] He also split the Abelisauridae into two subfamilies; the Abelisaurinae (all abelisaurids more closely related to Abelisaurus than to Carnotaurus) and Carnotaurinae (all abelisaurids more closely related to Carnotaurus than to Abelisaurus).[2]
- Sampson and others described a more complete specimen of Majungatholus atops. They performed an X-ray CT scan of the skull of Majungatholus atopus. They found that the dome on the animal's skull formed of its frontal bone was actually hollow. This suggests that this structure was purely for display rather than used in fights between Majungatholus.[6]

2000
