Gondwanasuchus is an extinct genus of baurusuchid mesoeucrocodylian from the Late Cretaceous Adamantina Formation of Brazil. The type species is Gondwanasuchus scabrosus.

 80 миллионов лет назад на юго-востоке современной Бразилии обитало множество разнообразных крокодилов. Некоторые из них так вошли в роль сухопутных хищников, что начали всерьез конкурировать с динозаврами-тероподами. Одного из таких "динокроков" описали недавно бразильские палеонтологи.

 Профессор палеонтологии университета Бразилиа (UnB) Рикардо Пинта объяснил, почему Gondwanasuchus не был динозавром. "Он принадлежит к группе крокодиломорфов, не очень разнообразной, зато дожившей до наших дней. В прошлом сухопутные крокодиломорфы были довольно успешными", – сообщил профессор. Открытие очередного ископаемого, по его словам, помогает исследователям реконструировать сценарии прошлого и таким образом лучше представить себе историю развития жизни на Земле. Особенно любопытным оказалось то, что в местности, где обитал гондваназух и еще шесть других видов крокодиломорфов из его семейства, было довольно мало хищных динозавров.

 "Вполне возможно, что крокодиломорфы просто лучше сохранялись в этих местах, и они были более многочисленны, чем плотоядные динозавры. Но разнообразие форм крокодилов и их образ жизни удивили нас. Они занимали самые разные экологические ниши. G. scabrosus, например, имел прекрасное бинокулярное зрение, которое помогало ему точно оценивать расстояние до жертвы перед нападением. Такие адаптации имели и некоторые хищные динозавры. Вполне возможно, что крокодиломорфы вытеснили динозавров из экологической ниши среднеразмерных хищников, и именно поэтому остатки последних так редки в этих местах. Бассейн Бауру в меловом периоде был землей крокодиломорф", – подчеркнул, в свою очередь Марино.

 Стоит отметить, что в честь бассейна Бауру было названо семейство сухопутных крокодиломорфов Baurusuchidae, особенно обильных в этом регионе и особенностями строения напоминавших динозавров-тероподов. Ранее бразильские палеонтологи уже описали отсюда четрехметрового Stratiotosuchus maxhechti, охотившегося на своих динозавров, и двухметрового Campinasuchus dinizi с клыками, сделавшими бы честь саблезубому тигру.

 Название рода образовано от древнего суперконтинента Гондвана и греческого слова "suchus" - крокодил. Видовое имя в переводе с латыни обозначает шероховатый или зазубренный.

 Гондваназух был современником титанозавров, которые считаются одними из самых крупных сухопутных животных. Их вес мог достигать 100 тонн. Ископаемые остатки помогают нам восстановить древнюю историю Земли. Например, благодаря тому, что окаменелости некоторых животных находят в разных частях света, мы смогли узнать о распаде Гондваны. Мелкие окаменелости используются геологами, например, при поисках нефти, помогая им в определении возраста горных пород.

 Stratiotosuchus (from Greek, στρατιώτης (stratiōtēs, "soldier") and σοῦχος (suchos, "crocodile")) is an extinct genus of baurusuchid mesoeucrocodylian from the Adamantina Formation in Brazil. It lived during the Late Cretaceous. The first fossils were found in the 1980s, and the type species Stratiotosuchus maxhechti was named in 2001. A hyperpredator, it and other baurusuchids may have filled niches occupied elsewhere by theropod dinosaurs.

 Stratiotosuchus has a deep, laterally compressed skull 470 millimetres (1.54 ft) long. It reached up to 4 metres in length, making it about the same size as Baurusuchus. The teeth are ziphodont, meaning that they are laterally compressed, curved, and serrated. Like other baurusuchids, Stratiotosuchus has a reduced number of teeth: three in its premaxilla and five in its maxilla. When the jaw is closed, the teeth of the upper jaw overlie those of the lower jaw and shear closely together. Stratiotosuchus has one large caniniform tooth in its premaxilla, and several large maxillary teeth behind it. An enlarged fourth dentary tooth in the lower jaw also forms a canine, and is visible when the jaw is closed.

 Like all crocodyliforms, Stratiotosuchus was quadrupedal. Unlike the sprawling gait of crocodilians living today, Stratiotosuchus is thought to have been a fully erect quadruped. The transition from a sprawling, low to the ground posture in the ancestors of Stratiotosuchus to an erect, elevated posture involved a significant transformation of the limbs, hips, and shoulders.

 Large crests are present over the acetabulum, or hip socket, stabilizing the hip in what is known as a pillar-erect stance (the acetabular crest lies like a shelf on top of the femur to form a pillar). The ischium bone, which extends backward from the hip, has a large projection that in life would serve as a strong attachment site for the puboischiotibialis muscle. The puboischiotibialis is also present in living crocodilians and is used primarily to keep the legs upright in what is known as a high walk, in which they hold their legs underneath them while walking. The puboischiotibialis is very weak in living crocodilians, so they cannot sustain a high walk for very long. Stratiotosuchus is thought to have had a much stronger puboischiotibialis, allowing it to have a permanent upright stance.

 Stratiotosuchus also has a relatively straight femur bone; while the bone is somewhat twisted along its length, the degree of torsion is not as high as that of other crocodyliforms. The shape of the femur is more similar to that of rauisuchids and poposaurids, which were early crocodile relatives that are known to have had erect gaits. The femur even shares similarities with those of early theropod dinosaurs, which were fully bipedal. When compared to crocodilians, the top of the femur of Stratiotosuchus is rotated toward the front, so that the femoral head faces backward rather than medially inward. This position restricts the movement of the hindlimbs along a forward-backward or parasagittal axis. Muscles that attach to the side of the leg in crocodilians would have attached to the back of the leg in Stratiotosuchus, enabling a powerful backward extension of the hind leg.

 The arm socket faces backwards and downwards from a bone in the shoulder girdle called the coracoid, suggesting that the arms were held beneath the body. The large articular surface on the head of the humerus implies that the arms had a wide range of movement, but restricted to a parasagittal axis. The deltopectoral crest on the front of the humerus would have anchored large arm muscles to bring the arm forward while walking. Modern crocodilians also have a deltopectoral crest, but it is positioned laterally and anchors to muscles that pull the arms up to the sides, not forward. The muscle thought to have facilitated forward movement in Stratiotosuchus is called the deltoideus clavicularis; it is also present in modern crocodilians, which use it for high walking.

 Other features that suggest an erect posture are tightly clustered metacarpals forming narrow hands well-suited for walking and a backward-projecting calcaneal tuberosity in the ankle, which would have attached to muscles that fixed the lower limb in a parasagittal axis. A backward-projecting calcaneal tuberosity is present in most early crocodilian relatives, including those that are thought have sprawling gaits, yet modern crocodilians have more laterally projected tuberosities impeding a parasagittal orientation of the hind foot.

 The first known fossil of Stratiotosuchus was a nearly complete skeleton, cataloged as DGM 1477-R. It was found by paleontologist José Martin Suárez in the town of Irapuru in São Paulo State in 1988. This skeleton and all other specimens of Stratiotosuchus come from the Adamantina Formation, which is either Turonian-Santonian in age (about 85 million years old) or Campanian-Maastrichtian in age (about 70 million years old). DGM 1477-R includes a nearly complete skull, partial lower jaw, vertebral column, and limb bones. The skeleton was identified as that of a baurusuchid, closely related but distinct from Baurusuchus pachechoi, which had been known since 1945. Stratiotosuchus maxhechti was named in 2001 on the basis of this skeleton, designated the holotype of the species. Stratiotosuchus means "soldier crocodile" in Greek, and the species name honors paleontologist Max K. Hetch.

 Further preparation of DGM 1477-R revealed that two individuals were present in the same block of sandstone, as indicated by two extra leg bones, an extra fragment of the hip, and extra metatarsals. They are the same size as the other bones, suggesting that the second individual was equal in body size to the first.

 Stratiotosuchus has been recognized as a baurusuchid since it was first described in 1988. In 2004, Baurusuchidae was even defined as the most recent common ancestor of Baurusuchus and Stratiotosuchus and all of its descendants; thus, the definition of Baurusuchidae relies on the inclusion of Stratiotosuchus. Stratiotosuchus and Baurusuchus both belong to a large clade called Metasuchia, which includes living crocodilians and many extinct relatives extending back into the Jurassic. However, the exact position of Stratiotosuchus and Baurusuchus within Metasuchia is still uncertain. Below are several possibilities that have been uncovered in various phylogenetic analyses:

 Baurusuchidae is grouped with the family Sebecidae in a clade called Sebecosuchia.

 Sebecids are closer to Neosuchia (the group including modern crocodilians), while baurusuchids are either basal metasuchians or deeply nested within Notosuchia, a large clade of extinct metasuchians.

 Baurusuchidae is polyphyletic, with Stratiotosuchus and Baurusuchus positioned as basal metasuchians while other baurusuchids are placed in the clade Sebecia along with sebecids. This also makes Sebecosuchia polyphyletic.

 Montefeltro et al. (2011) found support for baurusuchids as advanced notosuchians, and divided the family into two subfamilies, Baurusuchinae and Pissarrachampsinae. Stratiotosuchus belonged to Baurusuchinae along with Baurusuchus.

 Another phylogenetic analysis of baurusuchids was conducted by Riff and Kellner (2011). Their analysis placed Stratiotosuchus and Baurusuchus deep within Notosuchia, as the sister taxon of the family Sphagesauridae.

 Based on the types of deposits in the Adamantina Formation, Stratiotosuchus most likely lived alongside a river system with many small ephemeral lakes.

 With a fully erect stance, Stratiotosuchus has many features convergent with theropod dinosaurs, which are fully bipedal. In Stratiotosuchus, a roughly surfaced region on the upper part of the femur is analogous to the accessory trochanter common to tetanuran theropods. These projections are thought to have anchored the same muscle, called the puboischiofemoralis internus pars dorsalis. A crest on the forward edge of the tibia is similar to those seen in early theropod dinosaurs. The articular surface of the tibia that attaches to the femur is laterally compressed, which is unlike the more circular surface in living crocodilians and more like that of a theropod dinosaur. On the hip of Stratiotosuchus, a depression on the ilium is convergent with the brevis fossa of dinosaurs, and the small bump anchoring the puboischiotibialis muscle is convergent with the obturator tubercle of maniraptoriform theropods.

 Along with anatomical similarities, Stratiotosuchus and other baurusuchids are thought to have had lifestyles very similar to those of theropod dinosaurs. While many small carnivorous crocodyliforms are known from the Adamantina Formation, Stratiotosuchus and Baurusuchus are believed to have been the only large carnivores the Adamantina ecosystem. Decades of paleontological exploration in these deposits have uncovered only a few theropod dinosaur bones, so it appears that baurusuchids like Stratiotosuchus occupied the niche of top predators in the absence of these dinosaurs. A nearby Cretaceous deposit in Argentina called the Neuquén Group also contains baurusuchids, but they are much smaller than Stratiotosuchus and were likely out-competed by the wide range of theropod dinosaurs known from these deposits. In the absence of large theropods, carnivores like Stratiotosuchus may have fed on large herbivorous titanosaurs, including Adamantisaurus, Aeolosaurus, Gondwanatitan, and Maxakalisaurus.

 Pseudosuchians superficially resembling Stratiotosuchus were the top predators of the Triassic period, until they were decimated by the Triassic–Jurassic extinction event and replaced by large theropods. The appearance of Stratiotosuchus and other baurusuchids marks a brief recovery of this top position during the Late Cretaceous.

 Pissarrachampsa (meaning "piçarra [the local name for the sandstones it was recovered from] crocodile") is an extinct genus of baurusuchid mesoeucrocodylian from the Late Cretaceous of Brazil. It is based on a nearly complete skull and a referred partial skull and lower jaw from the Campanian - Maastrichtian-age Vale do Rio do Peixe Formation of the Bauru Group, found in the vicinity of Gurinhatã, Brazil.

 Pissarrachampsa is known from a nearly complete holotype skull with the tip of the snout eroded away. The end of the snout and the bottom of the palate are also represented by a second fossil. Like other baurusuchids, it has a deep skull that narrow in front of the eyes and wider at the back, giving it a roughly triangular shape when viewed from above. The snout is not as narrow as other related baurusuchids, however. At around 70% the length of the entire skull, the snout is also short in comparison to those of other crocodyliforms. Like other baurusuchids, Pissarrachampsa has an enlarged caniniform tooth in the upper jaw. Including the enlarged caniniform, there are four teeth implanted in the maxilla, less than other baurusuchids. A groove extends behind the last of the maxillary teeth. While other baurusuchids have more teeth implanted this groove, Pissarrachampsa likely lost these teeth, giving it a reduced dentition. A deep notch between the maxillae and premaxillae provides room for an enlarged fourth dentary tooth in the lower jaw when the mouth is closed. Another large dentary tooth fits into a hole at the back of the upper jaw. Except for the fourth dentary tooth, no teeth in the lower jaw are visible when the mouth is closed.

 The nostrils are positioned at the tip of the snout and face forward. They are found in a depressed region called the circumnarial fossa. Thick palpebral bones overly the eyes. The supratemporal fenestrae, two large holes on the skull roof, are almost the same size as the eye sockets and are roughly triangular in shape. The thick anterior and medial rims of the supratemporal fenestrae are a diagnostic feature of Pissarrachampsa. At the back of the skull are four quadrate fenestrae, small depressions that Pissarrachampsa shares with other notosuchians. In Pissarrachampsa, these fenestrae are visible when the skull is viewed from the side, but in other baurusuchids, they are hidden within a deep notch in the back of the skull. The pterygoid wings extend down from the bottom of the skull as two large triangular pieces of bone. A deep depression on each wing serves as another diagnostic characteristic of the genus. Another unique feature can be found underneath the back of the skull; four holes called Eustachian foramina provide an opening for the Eustachian tubes, and in Pissarrachampsa the outer or lateral pair are larger than the inner or medial pair.

 Интересную находку удалось обнаружить простому муниципальному служащему из маленького городка в одном из бразильских штатов Минас-Жерайс еще в 2008 году. Ранее этой находкой никто не интересовался. Но недавно об этом узнали палеонтологи из Университета Сан-Паулу и канадского Университета Макгилла.
Когда ученые увидели окаменелый скелет, они поняли, что это необычный представитель отряда крокодиломорф. В ходе детального изучения останков, было установлено, что их возраст составляет более 70 миллионов лет, а найденный вид принадлежит к семейству баурузухид (Baurusuchidae). Еще одним интересным моментом, который привлек внимание ученых, было то, что голова найденного крокодила, больше походила на голову собаки, чем на голову современных крокодилов.

  Стоит отметить, что наука уже давно признала большие различия между представителями семейства баурузухид и другими крокодиломорфами. До недавнего времени баурузухии были прекрасно изучены и описаны во многих трудах по палеонтологии. Но теперь, ученые получили целый череп крокодила, принадлежавшего к неизвестному ранее виду. Этого представителя корокодиломорф назвали Pissarrachampsa sera.

  Со слов одного из ученых проводивших исследования останков этого ископаемого Ханса Ларсона стало понятно, что современная наука не располагает глубокими знаниями об этом виде, а лишь только предположениями об их анатомическом строении и способе жизни. На основе анализа данных полученных в ходе исследования останков крокодиломорфа, ученые предположили, что представители семейства баурузухид были высокого роста, имели увеличенные клыки в пасти и долговязое, подвижное тело.
 
  Кроме того, было сделано предположение о том, что способ жизни этих животных напоминал способ жизни диких собак. К такому выводу ученые пришли после детального изучения количества и размеров зубов. Эти крокодиломорфы могли охотиться на животных такого же размера, что и они сами, примерно от 4 до 6 метров в длину. Данные животные благодаря своему стереоскопическому зрению, могли точно определить расстояние до жертвы, а затем догнать ее на своих удлиненных ногах.

  Нельзя оставить без внимания и другие предположения ученых, о том, что найденные останки могли принадлежать динозавру. Но такое предположение крайне сомнительно, поскольку найденный череп имеет признаки, характерные для крокодиломорф позднего мелового периода.

 После сравнения Pissarrachampsa sera с другими баурузухиями, палеонтологи обнаружили большие отличия в строении нового вида. "Мы имеем дело с исключительно далеко расходящимися линиями крокодиловых. Предстоит найти еще много окаменелостей, чтобы связать этого крокодиломорфа с его предшественниками и потомками в процессе эволюции”, – убежден один из авторов исследования Фелипе Монтефельтро (Felipe Montefeltro).

 Campinasuchus is an extinct genus of baurusuchid mesoeucrocodylian from Minas Gerais State of Brazil.

 Campinasuchus is known from four partial skulls from the Honorópolis District of the Adamantina Formation, Bauru Basin, dating to the Turonian or the Santonian stage of the late Cretaceous, about 93.5-83.5 million years ago. The specimens were collected at Três Antas Farm, Campina Verde County of the Minas Gerais State. The holotype CPP 1235 consists of a well preserved posterior skull and partial rostrum, and the paratypes, CPP 1234, partial skull, CPP 1236, nearly complete rostrum and CPP 1237, partial skull (including mandible) and associated postcranial skeleton. Campinasuchus is the fifth baurusuchid species from the Adamantina Formation to date.

 Campinasuchus, like other baurusuchids, was a fully terrestrial predator. It has a deep and laterally compressed skull with large, blade-like teeth. Compared to other baurusuchids, it has a very short, low snout. It is much narrower than the back of the skull. Its upper margin is also lower than the back of the skull, giving the head a slightly sloping profile (other baurusuchids have high snouts that are level with the rest of the skull). The third maxillary tooth of the upper jaw and the fourth dentary tooth of the lower jaw are greatly enlarged. A small pit on the premaxilla accommodates the first tooth of the mandible when the jaws are closed. This pit is positioned between the first and second premaxillary teeth. A deep notch forms the boundary between the premaxilla and maxilla, and provides an opening for the large fourth dentary tooth of the lower jaw. The supratemporal fenestrae, holes at the back of the skull, are relatively small. In other baurusuchids, the fenestrae are almost as large as the eye sockets.

 Campinasuchus was first named by Ismar De Souza Carvalho, Vicente De Paula Antunes Teixeira, Mara Lúcia Da Fonseca Ferraz, Luiz Carlos Borges Ribeiro, Agustín Guillermo Martinelli, Francisco Macedo Neto, Joseph J. W. Sertich, Gabriel Cardoso Cunha, Isabella Cardoso Cunha and Partícia Fonseca Ferraz in 2011 and the type species is Campinasuchus dinizi. The generic name is derived from Campina in reference to Campina Verde County in which Campinasuchus was found, and suchus, Latinized from the Greek souchos, an Egyptian crocodile god Sebek. The specific name honours the owners of the farm where the specimens were excavated: Izonel Queiroz Diniz Neto and the families Diniz and Martins Queiroz.

 Baurusuchus is an extinct genus of baurusuchid mesoeucrocodylian from the Late Cretaceous of Brazil. It was a terrestrial predator and scavenger, about 3.5 to 4 metres (11 to 13 ft) long and 80 to 100 kilograms (180 to 220 lb) in weight. Baurusuchus lived during the Turonian to Santonian stages (90-83.5 million years ago) of the Late Cretaceous Period, in Adamantina Formation, Brazil.^[2] It gets its name from the Brazilian Bauru Group ("Bauru crocodile"). It was related to the earlier-named Cynodontosuchus rothi, which was smaller, with weaker dentition (Bonaparte, 1996). The three species are B. pachechoi (Price, 1945), B. salgadoensis (Carvalho et al., 2005) (named after General Salgado County in São Paulo, Brazil) and B. albertoi (Nascimento & Zaher, 2010) (named after Dr. Alberto Barbosa de Carvalho, Brazilian paleontologist). Its relatives include the similarly sized Stratiotosuchus from the Adamantina Formation, and Pabweshi, from the Pakistani Pab Formation.

 B. salgadoensis is seen as a terrestrial predator, living in hot and arid climate. The position of the external nares was unsuited for an amphibious lifestyle like in modern crocodilians and the snout and teeth are laterally compressed like in theropods. Both of this supports the terrestrial hypothesis. The hot environment hypothesis is based on the lifestyle of modern crocodilians and the stratigraphy of Baurusuchus. B. salgadoensis was found in fine massive sandstones which are interpreted as a floodplain area in hot and arid climate. Baurusuchus was likely able to dig holes for finding water in dry seasons or, like modern alligators do, for thermoregulation. The occurrence of very complete skeletons in correlated stratigraphic levels supports this. Such a strategy would have made it less water-bound than most modern crocodiles, allowing it to live in more continental climate. The strongly bent pterygoids suggest a powerful bite and that Baurusuchus could close it's jaw very quickly. The skull and teeth morphology (biology) indicates that the biting strategies of Baurusuchus were similar to a komodo dragon which include ambushing the prey, biting it and pulling back the serrated, blade-like teeth. Baurusuchus likely played an important role in it's ecosystem, competing with the abelisaurids for food.

 Баурузух - сухопутный крокодиломорф позднего мелового периода из местности Бауру (Бразилия).

 Тяжелый, мощный, уплощенный с боков череп, скорее предназначенный, для продирания сквозь густую кустарниковую растительность, нежели чем для охоты в водной среде. Возможно, конкурировал с хищными динозаврами (абелизавридами).

 Удивительная особенность этой рептилии – на черепе явные признаки строения, свойственные только крупным плотоядным динозаврам: это antorbital fenestra – широкое отверстие между ноздрями и глазницами, которое появилось еще у архозавров в раннем Триасовом периоде, этот признак сохранили птицы, но полностью утратили современные крокодилы.

 Кроме того баурузух отличался невысокими гребнями сверху черепа. Строение крестцовых позвонков явно свидетельствует об успешном приспособлении к активному перемещению по суше.

 Имел высокие грацильные (почти собачьи по строению) лапы. Специалисты в 2010 году предположили, что по строению передних конечностей вполне был способен в засушливые периоды вырывать достаточно глубокие ямы в поисках воды

 Sebecosuchia is an extinct group of mesoeucrocodylian crocodyliforms that includes the families Sebecidae and Baurusuchidae. The group first appeared in the Late Cretaceous with the baurusuchids and went extinct in the Miocene with the last sebecids. Fossils have been found primarily from South America but have also been found in Europe, North Africa, and Asia. Some recent studies have separated Baurusuchidae and Sebecidae, making Sebecosuchia polyphyletic, but others have retained it as a valid grouping.

 Sebecosuchia was first constructed in 1946 by American paleontologist Edwin Colbert to include Sebecus and Baurusuchidae. Sebecus, which had been known from South America since 1937, was an unusual crocodyliform with a deep snout and teeth that were ziphodont, or serrated and laterally compressed. The family Baurusuchidae was named the year before and included the newly described Baurusuchus, which was also a South American deep-snouted form.

 More recently, other crocodyliforms have been assigned to Sebecosuchia that cannot be placed into either family. These include the genera Eremosuchus, named in 1989, and Pehuenchesuchus, named in 2005. They are usually considered to be more basal sebecosuchians than the sebecids and baurusuchids.

 Baurusuchidae is a Gondwanan family of mesoeucrocodylians that lived during the Late Cretaceous. It is a group of terrestrial hypercarnivorous crocodilians from South America (Argentina and Brazil) and possibly Pakistan. Baurusuchidae has been defined as a clade containing the most recent common ancestor of Baurusuchus and Stratiotosuchus and all of its descendants. It may, however, be polyphyletic, as recent phylogenetic analyses have placed Baurusuchus within Notosuchia and other baurusuchids within the more distantly related clade Sebecia. A recent study of the family finds it monophyletic by including the South American genera Baurusuchus, Cynodontosuchus, Pissarrachampsa, Stratiotosuchus, and Wargosuchus. Other traditional baurusuchids like Pabwehshi are excluded. The recently named Campinasuchus is also included in the family. Baurusuchids have been placed in the suborder Baurusuchia, and two subfamilies have been proposed: Baurusuchinae and Pissarrachampsinae.

 Several genera have been assigned to Baurusuchidae. Baurusuchus was the first, being the namesake of the family. Remains of Baurusuchus have been found from the Late Cretaceous Bauru Group of Brazil in deposits that are Turonian - Santonian in age. In addition to Baurusuchus, five other South American crocodyliforms have been assigned to Baurusuchidae: Campinasuchus, Cynodontosuchus, Pissarrachampsa, Stratiotosuchus, and Wargosuchus. Cynodontosuchus was the first known baurusuchid, named in 1896 by English paleontologist Arthur Smith Woodward, although it was only recently assigned to Baurusuchidae. Wargosuchus was described in 2008.^[3] Cynodontosuchus and Wargosuchus are known only from fragmentary remains. Both genera are from the Santonian of Argentina.

 A fourth genus, Stratiotosuchus, was assigned to Baurusuchidae in 2001. Fossils have been found from the Turonian - Santonian of Brazil. Pabwehshi is the youngest genus that has been assigned to Baurusuchidae, and is from the Maastrichtian of Pakistan. It was named in 2001 but has since been reassigned as a basal member of Sebecia.

A new genus, Campinasuchus, was assigned to the family in May, 2011. It is known from the Turonian-Santonian Adamantina Formation of the Bauru Basin of Brazil. Soon after, the new genus Pissarrachampsa was named from the Campanian–Maastrichtian Vale do Rio do Peixe Formation, also in the Bauru Basin.
