Sebecidae

Barinasuchus (meaning "Barinas crocodile", in reference to where the type material was found) is an extinct genus of sebecid mesoeucrocodylian. It lived in Argentina, Peru, and Venezuela between the middle Eocene and the Late Miocene, ~42–11.6 Ma. Described in 2007, based on a severely damaged specimen from which only a snout tip was recovered, Barinasuchus is known from a single species, B. arveloi, named after Alberto Arvelo Torrealba, a local educator and poet.

Sebecidae is an extinct family of prehistoric terrestrial sebecosuchian crocodylomorphs, known from the Late Cretaceous and Cenozoic of Europe, South America and the Caribbean. They were the latest surviving group of non-crocodilian crocodylomorphs.

Bretesuchus is an extinct genus of sebecosuchian mesoeucrocodylian within the family Sebecidae known from northwestern Argentina. It was a large apex predator (total length approximately 4 m).

Sebecus (meaning "Sobek" in Latin) is an extinct genus of sebecid crocodylomorph from Paleogene period of South America. Like other sebecosuchians, it was entirely terrestrial and carnivorous. The genus is currently represented by two species, the type S. icaeorhinus and S. ayrampu. Several other species have been referred to Sebecus, but were later reclassified as their own genera.

Langstonia (meaning "[crocodile] of Langston", in honor of paleontologist Wann Langston, Jr.) is an extinct genus of notosuchian crocodylomorph of the family Sebecidae. It lived in the middle Miocene (specifically in the Laventan land-mammal age), in the "Monkey Beds" of the Colombian Villavieja Formation. Langstonia was named in 2007 by Alfredo Paolillo and Omar Linares for fossils originally described by Langston in 1965 as Sebecus huilensis. Thus, the type species is L. huilensis. == Discovery and naming == left|thumb|The Tatacoa Desert, in which has been discovered numerous Miocene fossil

Lorosuchus is an extinct genus of sebecid mesoeucrocodylian known from the Río Loro Formation in Tucumán Province of northwestern Argentina.

Zulmasuchus (meaning "Zulma Gasparini's crocodile") is an extinct genus of sebecid sebecosuchian mesoeucrocodylian. Its fossils have been found in Early Paleocene-age rocks (Danian stage) of the Santa Lucía Formation in Bolivia. Zulmasuchus was named in 2007 by Alfredo Paolillo and Omar Linares for fossils originally described by Buffetaut and Marshall in 1991 as Sebecus querejazus. Thus, the type species is Sebecus querezajus and the combinatio nova is Zulmasuchus querejazus.

Ayllusuchus is an extinct genus of medium-sized sebecid mesoeucrocodylian. Fossils have been found in the Lumbrera Formation of Argentina (Eocene age, Casamayoran). It possessed a relatively long and low snout compared to other sebecids.

Pehuenchesuchus (meaning "Pehuenche crocodile", after the Mapuche name for the region in which it was found) is an extinct genus of sebecosuchian mesoeucrocodylian. It was discovered in rocks of the late Turonian-Coniacian-age Upper Cretaceous Río Neuquén Formation (Neuquén Group, near Rincón de los Sauces, Neuquén, Argentina.

Sahitisuchus is an extinct genus of sebecid mesoeucrocodylian known from Rio de Janeiro State of southeastern Brazil. It contains a single species, Sahitisuchus fluminensis. It is a terrestrial sebecid, although it may also have adopted a semi-aquatic lifestyle to some degree, most probably coexisting with the semi-aquatic alligatorid Eocaiman itaboraiensis.

Dentaneosuchus is a genus of large bodied sebecid crocodylomorph from the Middle Eocene of Issel and Réalmont (France). Originally described as Atacisaurus crassiproratus, the discovery of additional remains led to it being placed in a separate genus in 2023. It was tentatively recovered as the basalmost member of the family Sebecidae. Because of this Dentaneosuchus could play an important part in deciphering the origins and dispersal of European sebecids, as their presence on the continent, far away from their primary range in South America, is still not entirely resolved. It reached a simila
