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, 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. Genera 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'', ''Pissarracha ...

Stratiotosuchus
''Stratiotosuchus'' (from Greek, (stratiōtēs, "soldier") and (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. Description ''Stratiotosuchus'' has a deep, laterally compressed skull long. ''Stratiotosuchus'' reached up to in total length (including tail), 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 on ...

Campinasuchus
''Campinasuchus'' is an extinct genus of baurusuchid mesoeucrocodylian from Minas Gerais State of Brazil. Description ''Campinasuchus'', like other baurusuchids, was a fully terrestrial predator. It had 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 ...

Aplestosuchus
''Aplestosuchus'' is an extinct genus of baurusuchid mesoeucrocodylian known from the Late Cretaceous Adamantina Formation of São Paulo, southern Brazil. It contains a single species, ''Aplestosuchus sordidus''. ''A. sordidus'' is represented by a single articulated and nearly complete skeleton, preserving the remains of an unidentified sphagesaurid crocodyliform in its abdominal cavity. The specimen represents direct evidence of predation between different taxa of crocodyliforms in the fossil record. Discovery ''Aplestosuchus'' is known solely from the holotype LPRP/USP 0229a, an articulated and nearly complete skeleton including the skull, housed at the Laboratório de Paleontologia, Universidade de São Paulo. Additionally, isolated teeth and skull bones of an unidentified sphagesaurid crocodyliform were preserved in the abdominal cavity of LPRP/USP 0229a, and assigned to the specimen number LPRP/USP 0229b. The find represents direct evidence of predation between different ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aphaurosuchus
''Aphaurosuchus'' is an extinct genus of baurusuchid mesoeucrocodylian known from the Late Cretaceous Bauru Basin of São Paulo, southern Brazil. It contains a single species, ''Aphaurosuchus escharafacies.'' Discovery and naming In 2012 the Laboratório de Paleontologia lead an expedition to the municipality of Jales, São Paulo State, excavating at the Fazenda Furnas site which had yielded baurusuchid remains during previous digs. This site, belonging to the Adamantina Formation/Vale do Rio do Peixe Formation, contained a nearly complete baurusuchid skeleton, specimen ''LPRP/USP 0697'', broken into six main blocks. The first block contains the skull, all cervical vertebrae with associated osteoderms as well as the first four thoracic vertebrae, both scapulae and articulated coracoids. The second block is made up of most of the postcranial skeletal from the 8th thoracic to the 9th caudal vertebra with the associated double row of parasagittal osteoderms, the posterior thoracic ...

Baurusuchus
''Baurusuchus'' is an extinct member of the ancestral crocodilian lineage, which lived in Brazil from 90 to 83.5 million years ago, in the Late Cretaceous period. Technically, it is a genus of baurusuchid mesoeucrocodylian. It was a terrestrial predator and scavenger, about long and 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 ("Bauru crocodile"). 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'' (named after General Salgado County in São Paulo, Brazil) and ''B. albertoi'' (named after Alberto Barbosa de Carvalho, Brazilian paleontologist). The latter species is disputed (see phylogeny section). Its relatives include the similarly sized '' Stratiotosuchus'' from the Adamant ...

Razanandrongobe
''Razanandrongobe'' (meaning "ancestor f thelarge 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 because the fragmentary remains resembled lineages among both the theropod dinosaurs and crocodylomorphs. Further remains (including a premaxilla and lower jawbone) had been discovered as early as 1972, but were not described until 2017 by Cristiano Dal Sasso and colleagues. These remains allowed them to confidently assign ''Razanandrongobe'' as the oldest-known member of the Notosuchia, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baurusuchinae
Baurusuchinae is a subfamily of baurusuchid crocodyliforms from the Late Cretaceous of Brazil. Named in 2011, it contains the baurusuchids '' Aphaurosuchus'', '' Aplestosuchus, Baurusuchus'' and '' Stratiotosuchus''. Baurusuchinae is one of two subfamilies of Baurusuchidae, the other being Pissarrachampsinae. Several features distinguish baurusuchines from pissarrachampsines and help diagnose the subfamily. The orbital section of the jugal is twice the depth of the infratemporal portion. There are depressions on the quadrate running from top to bottom. The condyle on the side of the quadrate is almost as wide as the middle condyle. The bottom of the choanal septum is smooth. The ridged border of the middle face of the angular does not overcome the front of the mandibular fenestra. The frontal bone, situated behind the prefrontals, is very wide. The skull of baurusuchines is relatively straight when viewed from above. Baurusuchinae is a stem-based taxon formally defined in 2021 ...

Eremosuchus
''Eremosuchus'' is an extinct genus of sebecosuchian mesoeucrocodylian. Fossils have been found from El Kohol, Algeria of Eocene age. It had serrated, ziphodont teeth. The genus was originally referred to the family Trematochampsidae in 1989. A close relation to the baurusuchids was also considered. However, it was only tentatively assigned to this family on the basis of a few features of the cranial skeleton. Some features, such as a broad concave symphysis and laterally compressed teeth, are not restricted to the trematochampsids and occur in some sebecosuchians such as ''Baurusuchus'' and ''Sebecus''. Other features such as the surangular forming part of the craniomandibular articulation can also be found in many basal mesoeucrocodylians. A later phylogenetic analysis placed ''Eremosuchus'' within the suborder Sebecosuchia. It is now thought to be one of many putatively assigned sebecosuchians that cannot be firmly placed within any one family. It is thought to be the closest ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency ...

Gondwana
Gondwana () was a large landmass, often referred to as a supercontinent, that formed during the late Neoproterozoic (about 550 million years ago) and began to break up during the Jurassic period (about 180 million years ago). The final stages of break-up, involving the separation of Antarctica from South America (forming the Drake Passage) and Australia, occurred during the Paleogene. Gondwana was not considered a supercontinent by the earliest definition, since the landmasses of Baltica, Laurentia, and Siberia were separated from it. To differentiate it from the Indian region of the same name (see ), it is also commonly called Gondwanaland. Gondwana was formed by the accretion of several cratons. Eventually, Gondwana became the largest piece of continental crust of the Palaeozoic Era, covering an area of about , about one-fifth of the Earth's surface. During the Carboniferous Period, it merged with Laurasia to form a larger supercontinent called Pangaea. Gondwana ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
