Notosuchia

Araripesuchus is a genus of extinct crocodyliform that existed during the Cretaceous period of the late Mesozoic era some 125 to 66 million years ago. Araripesuchus is generally considered to be a notosuchian (belonging to the clade Mesoeucrocodylia), characterized by the varied teeth types and distinct skull elements. Seven species have been referred to Araripesuchus, though it has been argued that the phylogenetic position of this genus is uncertain, and that taxonomic revision is required.

Notosuchia is a clade of primarily Gondwanan mesoeucrocodylian crocodylomorphs that lived during the Jurassic and Cretaceous. Some phylogenies recover Sebecosuchia as a clade within Notosuchia, others as a sister group (see below); if Sebecosuchia is included within Notosuchia its existence is pushed into the Late Miocene or Early Pliocene, about 7 to 4.5 million years ago. Fossils have been found from South America, Africa, Asia, and Europe. Notosuchia was a clade of terrestrial crocodilians that evolved a range of feeding behaviours, including herbivory (Chimaerasuchus), omnivory (Simosuchus

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 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.

Kaprosuchus is an extinct genus of mahajangasuchid crocodyliform. It is known from a single nearly complete skull collected from the Upper Cretaceous Echkar Formation of Niger. The name means "boar crocodile" from the Greek , kapros ("boar") and , soukhos ("crocodile") in reference to its unusually large caniniform teeth which resemble those of a boar. It has been nicknamed "BoarCroc" by Paul Sereno and Hans Larsson, who first described the genus in a monograph published in ZooKeys in 2009 along with other Saharan crocodyliforms such as Anatosuchus and Laganosuchus. The type species is K. saha

Anatosuchus ("duck crocodile", the name from the Latin anas ("duck") and the Greek souchos ("crocodile"), for the broad, duck-like snout) is an extinct genus of notosuchian crocodyliforms discovered in Gadoufaoua, Niger, and described by a team of palaeontologists led by the American Paul Sereno in 2003, in the Journal of Vertebrate Paleontology.

Mahajangasuchus is an extinct genus of crocodyliform which had blunt, laterally compressed and serrated teeth. The type species, M. insignis, lived during the Late Cretaceous; its fossils have been found in the Maevarano Formation in northern Madagascar. It was a fairly large predator, measuring up to long.

Notosuchus (; 'southern crocodile') is an extinct genus of South American notosuchian crocodyliforms. It was terrestrial, living approximately 85 million years ago in the Santonian stage of the Late Cretaceous.

Pakasuchus is a genus of notosuchian crocodyliform distinguished by its unusual mammal-like appearance, including mammal-like teeth that would have given the animal the ability to chew. It also had long, slender legs and a doglike nose. Fossils have been found in the Galula Formation of Rukwa Rift Basin of southwestern Tanzania, and were described in 2010 in the journal Nature. Pakasuchus is originally considered to lived approximately 105 million years ago, in the mid-Cretaceous, but later age of site is reconsidered to the late Cretaceous, Cenomanian to Campanian instead. The type species is

Razanandrongobe (meaning "ancestor [of the] large lizard" in Malagasy) is a genus of carnivorous ziphosuchian crocodyliform from the Middle Jurassic of Madagascar. It contains the type and only species Razanandrongobe sakalavae, named in 2004 by Simone Maganuco and colleagues based on isolated bones found in 2003. The remains, which included a fragment of maxilla and teeth, originated from the Bathonian-aged Sakaraha Formation of Mahajanga, Madagascar. While they clearly belonged to a member of the Archosauria, Maganuco and colleagues refrained from assigning the genus to a specific group beca

Uruguaysuchus is an extinct genus of crocodyliforms from the Late Cretaceous Guichón Formation of Uruguay. It was related to Simosuchus and Malawisuchus. It was of small to moderate size reaching an estimated length of .

Uruguaysuchidae is a family of notosuchian crocodyliforms that lived in South America and Africa during the Cretaceous period. It was formally defined under the PhyloCode in 2024 as "the most inclusive clade containing Uruguaysuchus aznarezi but not Baurusuchus pachecoi, Peirosaurus torminni, Mahajangasuchus insignis, Notosuchus terrestris, and Crocodylus niloticus." Below is a modified cladogram that depicts the preferred reference phylogeny, chosen from Fernández Dumont et al. (2020):

Mahajangasuchidae is an extinct family of notosuchian crocodyliforms. It currently contains two genera, Mahajangasuchus and Kaprosuchus, both of which lived during the Late Cretaceous in Gondwana. It is defined as the most inclusive clade containing Mahajangasuchus insignis but not Notosuchus terrestris, Simosuchus clarki, Araripesuchus gomesii, Baurusuchus pachecoi, Peirosaurus torminni, Goniopholis crassidens, Pholidosaurus schaumbergensis, or Crocodylus niloticus. Phylogenetically, Mahajangasuchidae is placed just outside pholidosaurids and more derived neosuchians.

Comahuesuchus is an extinct genus of notosuchian crocodylomorphs from the late Cretaceous of Argentina. It was described by palaeontologist José Bonaparte in 1991. The type species is C. brachybuccalis from the Santonian Bajo de la Carpa Formation. In 2023 another species, C. bonapartei from the Sierra Barrosa Formation and Portezuelo Formation, was assigned to the genus.

Pabwehshi (meaning "Pab [Formation] beast ["wehshi" in Urdu]") is an extinct genus of baurusuchine mesoeucrocodylian. It is based on GSP-UM 2000, a partial snout and corresponding lower jaw elements, with another snout assigned to it. These specimens were found in Maastrichtian-age Upper Cretaceous rocks of the Vitakri and Pab formations in Balochistan, Pakistan, and represent the first diagnostic crocodyliform fossils from Cretaceous rocks of South Asia. Pabwehshi had serrated interlocking teeth in its snout that formed a "zig-zag" cutting edge. Pabwehshi was named in 2001 by Jeffrey A.

Malawisuchus (meaning "Malawi crocodile") 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.

Iberosuchus (meaning "Iberian crocodile") is a genus of extinct sebecosuchian mesoeucrocodylian found in Western Europe from the Eocene. Remains from Portugal was described in 1975 by Antunes as a sebecosuchian crocodilian. This genus has one species: I. macrodon (meaning "large toothed). Iberosuchus was a carnivore. Unlike the crocodilians today, they were not aquatic but were instead terrestrial.

Morrinhosuchus is an extinct genus of notosuchian crocodyliform from the Late Cretaceous Adamantina Formation of Brazil. It is known from a mandible and a portion of the front of the skull collected from the municipality of Monte Alto in São Paulo state. Morrinhosuchus refers to Morrinho de Santa Luzia, a hill nearby the collection site of the holotype, while luziae refers to the chapel of Santa Luzia, which is located on top of the hill.

Ziphosuchia is a clade of mesoeucrocodylian crocodyliforms that includes notosuchians and sebecosuchians.

Bergisuchus is an extinct genus of small sebecosuchian mesoeucrocodylian known primarily from the Eocene Messel Pit in Germany. Few fossils of Bergisuchus have been discovered, only a single incomplete snout, a few partial lower jaws and some teeth. Despite being fragmentary, the jaw bones are enough to indicate that Bergisuchus had a short, deep, narrow snout and serrated teeth, quite unlike the broad flat snouts of modern crocodylians.

Notosuchidae is a Gondwanan family of notosuchians. They were small-bodied terrestrial crocodyliforms that lived during the Late Cretaceous.

Chimaerasuchus ("chimera crocodile") is an extinct genus of Chinese crocodyliform from the Early Cretaceous Wulong Formation. The four teeth in the very tip of its short snout gave it a "bucktoothed" appearance. Due its multicusped teeth and marked heterodonty, it is believed to have been an herbivore. Chimaerasuchus was originally discovered in the 1960s but not identified as a crocodyliform until 1995, instead thought to possibly be a multituberculate mammal. It is highly unusual, as only two other crocodyliforms (Notosuchus and an unnamed specimen from Malawi) have displayed any characteris

Sebecosuchia (meaning "Sobek crocodiles") 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, but Razanandrongobe pushes the origin of Sebecosuchia to the Middle Jurassic. The last surviving members of the group, the sebecids, appear to have lasted until the late Miocene or early Pliocene on the Greater Antilles. Fossils have been found primarily from South America but have also been found in Europe, North Africa, Madagascar, and the Indian

Libycosuchus is an extinct genus of North African crocodyliform possibly related to Notosuchus; it is part of the monotypic Libycosuchidae and Libycosuchinae. It was terrestrial, living approximately 95 million years ago in the Cenomanian stage of the Late Cretaceous. Fossil remains have been found in the Bahariya Formation in Egypt, making it contemporaneous with the crocodilian Stomatosuchus, and dinosaurs, including the famous Spinosaurus.

Comahuesuchidae is a family of notosuchian crocodyliforms. Constructed in 1991, it includes the genera Comahuesuchus and Anatosuchus. Among the characteristics that are unique to this family is an external naris that is inset into the tip of the snout. There is also a diastema, or gap between the teeth, at the tip of the upper and lower jaws. Both Anatosuchus and Comahuesuchus have maxillary tooth rows in the upper jaw that extend out and over the dentary tooth rows of the lower jaw.

Itasuchus is an extinct genus of crocodyliforms from the Late Cretaceous of Brazil. Fossils of the type species I. jesuinoi, first described in 1955 by Llewellyn Ivor Price, have been found from the Marília Formation, though later finds also support its presence in the sediments of the Presidente Prudente Formation.

Candidodon is an extinct genus of notosuchian mesoeucrocodylian. Fossils have been found in the Early Cretaceous Itapecuru Formation and Alcântara Formation in Brazil.
