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.
