Goniopholis is an extinct genus of goniopholidid crocodyliform that lived in Europe and North America during the Late Jurassic and Early Cretaceous. Like other goniopholidids, it resembled living crocodilians, and probably had a similar ecology as semi-aquatic ambush predators.
Simosuchus is an extinct genus of notosuchian crocodyliforms from the Late Cretaceous of Madagascar. It is named for its unusually short skull. Fully grown individuals were about 0.75 metres (2.5 ft) in length. The type species is Simosuchus clarki, found from the Maevarano Formation in Mahajanga Province, although one isolated multicuspid tooth of this genus was discovered in Kallamedu Formation of India.
Chimaerasuchidae is a family of mesoeucrocodylians. It was erected as a clade in 2004 by Carvalho et al and included Chimaerasuchus from the Early Cretaceous of China and possibly also Simosuchus from the Late Cretaceous of Madagascar. The validity of the clade has been questioned in later studies that found the two genera to be more distantly related.
Mariliasuchus is an extinct genus of Late Cretaceous notosuchian crocodyliforms found near Marilia, Brazil. The first bone remains were found and collected in 1995 by Brazilian paleontologist William Nava, in red rocks from the fossiliferous Adamantina Formation. Four years later, it was described as Mariliasuchus amarali, by Brazilian paleontologists Ismar de Souza Carvalho and Reinaldo J. Bertini.
Malawisuchus is an extinct genus of notosuchian mesoeucrocodylian from the Early Cretaceous Dinosaur Beds of Malawi. It was described in 1997 by Elizabeth Gomani as a member of the family Notosuchidae. The type species is M. mwakasyungutiensis, referring to Mwakasyunguti, the area of northern Malawi where it was found. It was classified as a member of the family Itasuchidae by Carvalho and colleagues in 2004.
Baurusuchus is an extinct genus of baurusuchid mesoeucrocodylian, which lived in Brazil from 90 to 83.5 million years ago, in the Late Cretaceous period. It was a terrestrial predator and scavenger, estimated to reach up to 113.4 kilograms (250 lb) in weight. Baurusuchus lived during the Turonian to Santonian stages of the Late Cretaceous Period, in Adamantina Formation, Brazil. It gets its name from the Brazilian Bauru Group. It was related to the earlier-named Cynodontosuchus rothi, which was smaller, with weaker dentition. The three species are B. pachechoi, named after Eng Joviano Pacheco, its discoverer, B. salgadoensis and B. albertoi. The latter species is disputed. Its relatives include the similarly sized Stratiotosuchus from the Adamantina Formation, and Pabweshi, from the Pakistani Pab Formation.
Peirosauridae is a Gondwanan family of mesoeucrocodylians that lived during the Cretaceous period. It was a clade of terrestrial crocodyliforms that evolved a rather dog-like skull, and were terrestrial carnivores. It was phylogenetically defined in 2004 as the most recent common ancestor of Peirosaurus and Lomasuchinae and all of its descendants. Lomasuchinae is a subfamily of peirosaurids that includes the genus Lomasuchus.
Baurusuchidae is a Gondwanan family of mesoeucrocodylians that lived during the Late Cretaceous. It is a group of terrestrial hypercarnivorous crocodilians from South America and possibly Pakistan. Baurusuchidae has been, in accordance with the PhyloCode, officially defined as the least inclusive clade containing Cynodontosuchus rothi, Pissarrachampsa sera, and Baurusuchus pachecoi. Baurusuchids have been placed in the suborder Baurusuchia, and two subfamilies have been proposed: Baurusuchinae and Pissarrachampsinae.
Sphagesaurus is an extinct genus of sphagesaurid notosuchian crocodylomorph from the Late Cretaceous of southwest São Paulo, southern Brazil.
The Adamantina Formation is a geological formation in the Bauru Basin of western São Paulo state, in southeastern Brazil.
Trematochampsidae is an extinct family of mesoeucrocodylian crocodyliforms. Fossils are present from Madagascar, Morocco, Niger, Argentina, and Brazil. Possible trematochampsids have been found from Spain and France, but classification past the family level is indeterminant. The trematochampsids first appeared during the Barremian stage of the Early Cretaceous and became extinct during the late Maastrichtian stage of the Late Cretaceous.
Candidodon is an extinct genus of notosuchian mesoeucrocodylian. Fossils have been found in the Early Cretaceous Itapecuru Formation in Brazil.
Eremosuchus is an extinct genus of sebecosuchian mesoeucrocodylian. Fossils have been found from El Kohol, Algeria of Eocene age. It had serrated, ziphodont teeth.
Candidodontidae is a family of notosuchian crocodyliforms. It was originally used in 2002 as a name for a clade that includes the genera Araripesuchus, Candidodon, and Malawisuchus. Later in 2004 the family was formally defined as a node-based taxon including Candidodon itapecuruense and Mariliasuchus amarali. A 2009 study redefined Candidodontidae as a stem-based taxon which included Candidodon, Malawisuchus, and possibly Mariliasuchus.
Sebecosuchia is an extinct group of mesoeucrocodylian crocodyliforms that includes the families Sebecidae and Baurusuchidae. The group was long thought to have first appeared in the Late Cretaceous with the baurusuchids and become extinct in the Miocene with the last sebecids, but Razanandrongobe pushes the origin of Sebecosuchia to the Middle Jurassic. Fossils have been found primarily from South America but have also been found in Europe, North Africa, Madagascar, and the Indian subcontinent.
Caipirasuchus is an extinct genus of sphagesaurid notosuchians known from the Late Cretaceous of northern São Paulo State and western Minas Gerais State, southeastern Brazil. The type species, C. paulistanus, was named in 2011. A second species, C. montealtensis, was referred to Caipirasuchus in 2013 after having been named in 2008 as a species of Sphagesaurus. A third species, C. stenognathus, was described in 2014. A fourth species, C. mineirus, was described in 2018. A fifth species, C. attenboroughi, was named in 2021 in honour of David Attenborough, and a sixth species, C. catanduvensis, was described in 2024, with a distinct chamber associated with the airways, possibly used in vocalization.
Barreirosuchus is an extinct genus of trematochampsid notosuchian known from the Late Cretaceous of São Paulo State, southeastern Brazil. It contains a single species, Barreirosuchus franciscoi. It is most closely resembles Caririsuchus camposi from the Araripe Basin and Itasuchus jesuinoi also from the Bauru Basin, and shares with them several synapomorphies.
Coelognathosuchia is an extinct clade of neosuchian crocodyliforms that includes all taxa more closely related to the family Pholidosauridae than to Bernissartia fagesii or Eusuchia. Martin et al. (2014) named the clade after finding goniopholidids and pholidosaurids to group together in their phylogenetic analysis of crocodyliform evolutionary relationships. In their analysis, Pholidosauridae was monophyletic and Goniopholididae was paraphyletic, being an assemblage of successively more basal taxa within Coelognathosuchia. Coelognathosuchia itself was positioned near the base of the larger clade Neosuchia as the sister group to a clade containing the Early Cretaceous neosuchian Bernissartia and Eusuchia, the group that includes all modern crocodilians and their closest extinct relatives.
The Presidente Prudente Formation is a geological formation of the Bauru Group in the Paraná Basin, located in Brazil whose strata date back to the Late Campanian to Early Maastrichtian.
Roxochampsa is an extinct genus of crocodylomorph from the Late Cretaceous of Brazil belonging to the sebecosuchian clade Itasuchidae. The type species is R. paulistanus.
