Trematochampsidae
Trematochampsidae is an extinct family of mesoeucrocodylian crocodylomorphs. Fossils are present from Madagascar, Morocco, Niger, Argentina, and Brazil (in the case of ''Caririsuchus'', where some specimens have been found in the Romualdo Member of the Santana Formation). Possible trematochampsids have been found from Spain and France, but classification past the family level is indeterminant. The trematochampsids first appeared during the Barremian stage of the Early Cretaceous and became extinct during the late Maastrichtian stage of the Late Cretaceous. Description Trematochampsids are deep-snouted and have a ziphodont tooth structure. The dentition differs from most other crocodilians in that the teeth are recurved, serrated, and lateromedially compressed. This may be an adaptation to a terrestrial or at least semiterrestrial lifestyle as such teeth would be better suited for cutting and tearing into prey as opposed to capturing them and holding them underwater.

Trematochampsa
''Trematochampsa'' is a dubious extinct genus of crocodyliform from the Late Cretaceous (Coniacian-Santonian age) In Beceten Formation of Niger. Taxonomy The type species, ''T. taqueti'', was described by Eric Buffetaut in 1974. A second species, ''T. oblita'', was named from Madagascar in 1979, but was renamed '' Miadanasuchus'' in 2009. ''Trematochampsa'' gives its name to the Trematochampsidae, a poorly known group of fossil crocodiles. However, the labile phylogenetic position of ''Trematochampsa'' in many studies has been attributed to character conflict, leading many authors to exclude this genus from many cladistic analyses, but Sertich et al. (2014) noted that the referred material of ''Trematochampsa'' consists of more than one crocodyliform taxon, so they opted to use only the cranial material in the dataset for the cladistic analysis of '' Rukwasuchus'' and recommended removing the postcranial material from ''Trematochampsa''. The analysis recovered ''Trematocham ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Mahajangasuchus
''Mahajangasuchus'' is an extinct genus of crocodyliform which had blunt, conical teeth. The type species, ''M. insignis'', lived during the Late Cretaceous; its fossils have been found in the Maevarano Formation in northern Madagascar. It was a fairly large predator, measuring up to long. Discovery and naming With the inception of the Mahajanga Basin Project (MBP) in 1993, led by Dr. David Krause, came a significant increase of discoveries and research into the fauna of the Maastrichtian Maevarano Formation in northern Madagascar. This included a variety of crocodylomorphs with the largest specimen being a well preserved disarticulated skeleton discovered in 1995 roughly 1 km south-east of the village of Berivotra. This skeleton, specimen ''UA 8654'', consisted of a complete left and partial right mandible, vertebrae of the cervical, dorsal, saccral and caudal regions, several ribs as well as material of the pectoral, pelvic girdle and limb bones.

Amargasuchus
''Amargasuchus'' is an extinct genus of crocodylomorph. It was a member of the Trematochampsidae, an enigmatic family of mesoeucrocodylians. Fossils have been found from the La Amarga Formation in Argentina and date back to the Barremian and Aptian stages of the Early Cretaceous. ''Amargasuchus'' inhabited a terrestrial paleoenvironment that existed during the Early Cretaceous in the Neuquén basin that was characterized by a system of braided rivers, lakes, and alluvial plains. Sauropod, abelisauroid, and stegosaur Stegosauria is a group of herbivorous ornithischian dinosaurs that lived during the Jurassic and early Cretaceous periods. Stegosaurian fossils have been found mostly in the Northern Hemisphere, predominantly in what is now North America, Europe, ...ian dinosaurs have also been found existing in the Neuquén basin at this time. The holotype was discovered in 1984 in association with the dicraeosaurid sauropod dinosaur '' Amargasaurus''. References ...

Barreirosuchus
''Barreirosuchus'' is an extinct genus of trematochampsid notosuchian known from the Late Cretaceous of São Paulo State, southeastern Brazil. It contains a single species, ''Barreirosuchus franciscoi''. It is most closely resembles '' Caririsuchus camposi'' from the Araripe Basin and '' Itasuchus jesuinoi'' also from the Bauru Basin, and shares with them several synapomorphies. Discovery ''Barreirosuchus'' is known only from the holotype specimen MPMA-04-0012/00, an undeformed posterior portion of the skull with six teeth and a series of four vertebrae, two dorsal and two sacral. It was found four kilometer from Monte Alto County, in the escarpment of the Serra do Jabuticabal, in the rural area of Monte Alto, São Paulo. It was collected from the Adamantina Formation of the Bauru Basin, which dates to the Turonian and Santonian stages of the Late Cretaceous. Etymology ''Barreirosuchus'' was first named by Fabiano Vidoi Iori and Karina Lucia Garcia in 2012 and the type ...

Bergisuchus
''Bergisuchus'' is an extinct genus of small sebecosuchian mesoeucrocodylian known primarily from the Eocene Messel Pit in Germany. Few fossils of ''Bergisuchus'' have been discovered, only a single incomplete snout, a few partial lower jaws and some teeth. Despite being fragmentary, the jaw bones are enough to indicate that ''Bergisuchus'' had a short, deep, narrow snout and serrated teeth, quite unlike the broad flat snouts of modern crocodylians. As with other sebecosuchians, it is likely that ''Bergisuchus'' was a fast, terrestrial predator and not an aquatic ambush hunter like modern crocodylians. Its presence in Europe is also unusual, as later sebecosuchians were restricted entirely to South America, and so ''Bergisuchus'' indicates the group was once much more widespread in the early Cenozoic. History of Discovery ''Bergisuchus'' was first discovered by Dr. Dietrich Berg from the German Messel Pit in 1966, who originally classified it as an unnamed new species of seb ...

Maastrichtian (geological Period)
The Maastrichtian () is, in the ICS geologic timescale, the latest age (uppermost stage) of the Late Cretaceous Epoch or Upper Cretaceous Series, the Cretaceous Period or System, and of the Mesozoic Era or Erathem. It spanned the interval from . The Maastrichtian was preceded by the Campanian and succeeded by the Danian (part of the Paleogene and Paleocene). The Cretaceous–Paleogene extinction event (formerly known as the Cretaceous–Tertiary extinction event) occurred at the end of this age. In this mass extinction, many commonly recognized groups such as non-avian dinosaurs, plesiosaurs and mosasaurs, as well as many other lesser-known groups, died out. The cause of the extinction is most commonly linked to an asteroid about wide colliding with Earth, ending the Cretaceous. Stratigraphic definitions Definition The Maastrichtian was introduced into scientific literature by Belgian geologist André Hubert Dumont in 1849, after studying rock strata of the Chalk Gro ...

Barremian
The Barremian is an age in the geologic timescale (or a chronostratigraphic stage) between 129.4 ± 1.5 Ma ( million years ago) and 121.4 ± 1.0 Ma). It is a subdivision of the Early Cretaceous Epoch (or Lower Cretaceous Series). It is preceded by the Hauterivian and followed by the Aptian Stage.See Gradstein ''et al.'' (2004) or the online geowhen database (link below) Stratigraphic definitions The original type locality for the Barremian Stage is in the vicinity of the village of Barrême, Alpes-de-Haute-Provence, France. Henri Coquand defined the stage and named it in 1873. The base of the Barremian is determined by the first appearance of the ammonites ''Spitidiscus hugii'' and ''Spitidiscus vandeckii''. The end of the Barremian is determined by the geomagnetic reversal at the start of the M0r chronozone, which is biologically near the first appearance of the ammonite '' Paradeshayesites oglanlensis''.

Early Cretaceous
The Early Cretaceous (geochronological name) or the Lower Cretaceous ( chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 145 Ma to 100.5 Ma. Geology Proposals for the exact age of the Barremian-Aptian boundary ranged from 126 to 117 Ma until recently (as of 2019), but based on drillholes in Svalbard the defining early Aptian Oceanic Anoxic Event 1a (OAE1a) was carbon isotope dated to 123.1±0.3 Ma, limiting the possible range for the boundary to c. 122–121 Ma. There is a possible link between this anoxic event and a series of Early Cretaceous large igneous provinces (LIP). The Ontong Java- Manihiki- Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history. The Ontong Java Plateau today covers an area of 1,860,000 km2. In the Indian Ocean another LIP began to form at c. 120 Ma, the Kergue ...
