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 ...

Baurusuchid
Baurusuchidae is a Gondwanan Family (biology), 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 (biology), suborder Baurusuchia, and two Subfamily (biology), 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: ''Campin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 one l ...

Baurusuchus Pachecoi
''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 Adamanti ...

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 ...

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] |
Pissarrachampsinae
Pissarrachampsinae is a subfamily of baurusuchid crocodyliforms from the Late Cretaceous of Brazil and Argentina. It was named in 2011 with the description of ''Pissarrachampsa sera'' and includes ''P. sera'' from Brazil and the related ''Wargosuchus australis'' from Argentina. Pissarrachampsinae is one of two subfamilies of Baurusuchidae, the other being Baurusuchinae. Pissarrachampsines are distinguished from baurusuchines mainly by the shapes of bones on the tops of their skulls. The nasals and frontal touch each other at only a small point on the midline of the skull. The frontal bone, which is positioned directly behind the prefrontals, bears a groove that runs along its midline. Pissarrachampsines also have a pitted depression at the tip of the snout called the circumnarial fossa. The nostril openings are found within this fossa. Phylogenetically, Pissarrachampsinae is a stem-based taxon. When it was named, Pissarrachampsinae was defined as ''Pissarrachampsa sera'' and all ...

Campanian
The Campanian is the fifth of six ages of the Late Cretaceous Epoch on the geologic timescale of the International Commission on Stratigraphy (ICS). In chronostratigraphy, it is the fifth of six stages in the Upper Cretaceous Series. Campanian spans the time from 83.6 (± 0.2) to 72.1 (± 0.2) million years ago. It is preceded by the Santonian and it is followed by the Maastrichtian. The Campanian was an age when a worldwide sea level rise covered many coastal areas. The morphology of some of these areas has been preserved: it is an unconformity beneath a cover of marine sedimentary rocks. Etymology The Campanian was introduced in scientific literature by Henri Coquand in 1857. It is named after the French village of Champagne in the department of Charente-Maritime. The original type locality was a series of outcrop near the village of Aubeterre-sur-Dronne in the same region.

Sympatric
In biology, two related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter one another. An initially interbreeding population that splits into two or more distinct species sharing a common range exemplifies sympatric speciation. Such speciation may be a product of reproductive isolation – which prevents hybrid offspring from being viable or able to reproduce, thereby reducing gene flow – that results in genetic divergence. Sympatric speciation may, but need not, arise through secondary contact, which refers to speciation or divergence in allopatry followed by range expansions leading to an area of sympatry. Sympatric species or taxa in secondary contact may or may not interbreed. Types of populations Four main types of population pairs exist in nature. Sympatric populations (or species) contrast with parapatric populations, which contact one another in adjacent but not shared ranges and do ...
