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 ''Trematochampsa'' a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Miadanasuchus
''Miadanasuchus'' is an extinct genus of peirosaurid which existed in the Maevarano Formation of Madagascar during the late Cretaceous period (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 s ... age). It was first named by Erin L. Rasmusson Simons and Gregory A. Buckley in 2009 and the type species is ''Trematochampsa oblita''. Its teeth were irregularly spaced and variable in height.

Rukwasuchus
''Rukwasuchus'' is an extinct genus of peirosaurid mesoeucrocodylian known from the middle Cretaceous Galula Formation of southwestern Tanzania. It contains a single species, ''Rukwasuchus yajabalijekundu''. Discovery ''Rukwasuchus'' is known from its holotype, RRBP 08630, a well-preserved rear part of the skull including the cranial table, braincase, and interorbital region lacking the rostrum, the front portion of the palate, both lacrimals, jugals, and quadratojugals, as well as the mandible. RRBP 08630 was collected during 2008 at Namba 2 locality (also known as RRBP 2007-02), together with the titanosaurian '' Rukwatitan bisepultus'' which is exclusive to this locality. Material referred to ''Rukwasuchus'' includes four isolated teeth, which came from the neighboring localities RRBP 2007-01 yielding the 3 teeth RRBP 07351, 07369, 09362, and RRBP 2009-01 yielding the tooth RRBP 09367.

Cretaceous Niger
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth by the ...

Prehistoric Pseudosuchian Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Éric Buffetaut
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lacrimal Bone
The lacrimal bone is a small and fragile bone of the facial skeleton; it is roughly the size of the little fingernail. It is situated at the front part of the medial wall of the orbit. It has two surfaces and four borders. Several bony landmarks of the lacrimal bone function in the process of lacrimation or crying. Specifically, the lacrimal bone helps form the nasolacrimal canal necessary for tear translocation. A depression on the anterior inferior portion of the bone, the lacrimal fossa, houses the membranous lacrimal sac. Tears or lacrimal fluid, from the lacrimal glands, collect in this sac during excessive lacrimation. The fluid then flows through the nasolacrimal duct and into the nasopharynx. This drainage results in what is commonly referred to a runny nose during excessive crying or tear production. Injury or fracture of the lacrimal bone can result in posttraumatic obstruction of the lacrimal pathways. Structure Lateral or orbital surface The lateral or orbital surface i ...

Neosuchia
Neosuchia is a clade within Mesoeucrocodylia that includes all modern extant crocodilians and their closest fossil relatives. It is defined as the most inclusive clade containing all crocodylomorphs more closely related to ''Crocodylus niloticus'' (the Nile Crocodile) than to ''Notosuchus terrestris''. Members of Neosuchia generally share a crocodilian-like bodyform adapted to freshwater aquatic life, as opposed to the terrestrial habits of more basal crocodylomorph groups. The earliest neosuchian is suggested to be the Early Jurassic ''Calsoyasuchus'', which lived during the Sinemurian and Pliensbachian stages in North America. It is often identified as a member of Goniopholididae, though this is disputed, and the taxon may lie outside Neosuchia, which places the earliest records of the group in the Middle Jurassic. Characteristics A tooth notch between the maxilla and premaxilla is a basal characteristic of the Neosuchia, although it is lost in some more derived forms, most nota ...

Notosuchus
''Notosuchus'' (; 'southern crocodile') is an extinct genus of South American notosuchian crocodylomorph. It was terrestrial, living approximately 85 million years ago in the Santonian stage of the Late Cretaceous. Description ''Notosuchus'' was relatively small, reaching in length and a weight of . Remains have been found in the Bajo de la Carpa Formation in Patagonia, Argentina. First named in 1896, ''Notosuchus'' was the first known notosuchian. The type species is ''N. terrestris''. A second species, ''N. lepidus'', was named in 1957. A paper published in 2008 by Fiorelli and Calvo described new remains of the type species ''N. terrestris''. In it, the authors suggested that the skull would have supported a short trunk, or "hog's snout" as well as fleshy upper and lower lips. The anteriorly directed nares and the absence of a bony nasal septum (which presumably indicates cartilaginous tissue serving its place) provide evidence for a trunk-like snout, while striations on the ...

Anatosuchus
''Anatosuchus'' ("duck crocodile", the name from the Latin ''anas'' ("duck") and the Greek language, Greek ''souchos'' ("crocodile"), for the broad, duck-like snout) is an extinct genus of notosuchian Crocodylomorpha, crocodylomorph discovered in Gadoufaoua, Niger, and described by a team of palaeontologists led by the United States, American Paul C. Sereno, Paul Sereno in 2003, in the ''Journal of Vertebrate Paleontology''. Its duck-like snout coincidentally makes it resemble a crocoduck, an imagined hybrid animal with the head of a crocodile and the body of a duck. Discovery The type species of ''Anatosuchus'' is ''A. minor'', in reference to its small body size. The holotype material (MNN GDF603), is a nearly complete skull with articulated lower jaws, belonging to a juvenile. It was discovered from the upper portion of the Elrhaz Formation and lower portion of Echkar Formation, indicating an Early Cretaceous (Late Aptian or Early Albian) age. Another specimen was found later ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
