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.

In Beceten Formation
The In Beceten Formation, also Beceten or Ibecten is a Coniacian to Santonian geologic formation in the Iullemmeden Basin of Niger. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.Weishampel, et al. (2004). "Dinosaur distribution." Pp. 517-607. The lithology primarily consists of clays, fine limestones and sandy clays. Fossil content The following fossils have been reported from the formation: at Fossilworks.org ;Fish: * '' Amia sp.'' * '' Stromerichthys sp ...

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. All specimens came from approximately 25 km south of Lake Rukwa in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
