Stolokrosuchus
''Stolokrosuchus'' is an extinct genus of neosuchian crocodylomorph that lived during the Early Cretaceous. Its fossils, including a skull with a long thin snout and bony knobs on the prefrontal, have been found in Niger. ''Stolokrosuchus'' was described in 2000 by Hans Larsson and Boubacar Gado. The type species is ''S. lapparenti''. They initially described it as related to Peirosauridae, if not a member of that family. One study has shown it to be related to ''Elosuchus''. However, more recent works usually find ''Stolokrosuchus'' to be one of the basalmost neosuchian, only distantly related to the elosuchid or pholidosaurid, ''Elosuchus ''Elosuchus'' is an extinct genus of neosuchian crocodyliform that lived during the Middle Cretaceous of what is now Africa (Niger, Morocco and Algeria).

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 ...

Mahajangasuchidae
Mahajangasuchidae is an extinct family of notosuchian crocodyliforms. It currently contains two genera, '' Mahajangasuchus'' and '' Kaprosuchus'', both of which lived during the Late Cretaceous in Gondwana. It is defined as the most inclusive clade containing ''Mahajangasuchus insignis'' but not ''Notosuchus terrestris'', '' Simosuchus clarki'', '' Araripesuchus gomesii'', ''Baurusuchus pachecoi'', '' Peirosaurus torminni'', '' Goniopholis crassidens'', '' Pholidosaurus schaumbergensis'', or ''Crocodylus niloticus''. Phylogenetically, Mahajangasuchidae is placed just outside pholidosaurids and more derived neosuchians. Defining characters of the family include fused nasals, a jaw articulation below the posterior maxillary tooth row, a deep mandibular symphysis that is oriented anterodorsally, and the formation of a hornlike posterodorsal process from the squamosal and parietal (which is much more pronounced in ''Kaprosuchus'').

Notosuchia
Notosuchia is a suborder of primarily Gondwanan mesoeucrocodylian crocodylomorphs that lived during the Jurassic and Cretaceous. Some phylogenies recover Sebecosuchia as a clade within Notosuchia, others as a sister group (see below); if Sebecosuchia is included within Notosuchia its existence is pushed into the Middle Miocene, about 11 million years ago. Fossils have been found from South America, Africa, Asia, and Europe. Notosuchia was a clade of terrestrial crocodilians that evolved a range of feeding behaviours, including herbivory ('' Chimaerasuchus''), omnivory (''Simosuchus''), and terrestrial hypercarnivory (''Baurusuchus''). It included many members with highly derived traits unusual for crocodylomorphs, including mammal-like teeth, flexible bands of shield-like body armor similar to those of armadillos (''Armadillosuchus''), and possibly fleshy cheeks and pig-like snouts (''Notosuchus''). The suborder was first named in 1971 by Zulma Gasparini and has since undergone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elosuchid
''Elosuchus'' is an extinct genus of neosuchian crocodyliform that lived during the Middle Cretaceous of what is now Africa (Niger, Morocco and Algeria). Description and taxonomy ''Elosuchus'' had an elongated snout like a gharial and was probably a fully aquatic animal. The type species, ''E. cherifiensis'' from Algeria and Morocco, was originally described as a species of ''Thoracosaurus'' by Lavocat, but was recognized as a genus separate from ''Thoracosaurus'' by de Broin in 2002. ''Elosuchus felixi'', described from the Echkar Formation of Niger, was renamed ''Fortignathus'' in 2016 and is either a dyrosaurid relative or a non-hyposaurine dyrosaurid.de Broin, F. de L., 2002, ''Elosuchus'', a new genus of crocodile from the Lower Cretaceous of the North of Africa: C.

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.

Barrosasuchus
''Barrosasuchus'' is a genus of peirosaurid notosuchian from the Santonian of Argentina and part of the extensive peirosaurid record of Late Cretaceous Patagonia. It contains one species, ''Barrosasuchus neuquenianus''. ''B. neuquenianus'' is known from an almost complete skull and the majority of the articulated postcranial skeleton, making it the best preserved Patagonian peirosaurid. Discovery and naming In February of 2001 the Museo Carmen Funes conducted a joint expedition with the Royal Tyrell Museum at the Sierra Barrosa Locality, 30km north-east of Plaza Huincul, Neuquén province. There the team uncovered the bones of dinosaurs and mammals, bird footprints and notably a nearly complete peirosaurid fossil from the Bajo de la Carpa Formation. The holotype, MCF-PV 413, was found lying on its ventral side, the skull articulated with the remaining skeleton which consisted of both forelimbs, most of the vertebral column up to the sacrals, one hindlimb and semi-articulate oste ...

Pholidosaurid
Pholidosauridae is an extinct family of aquatic neosuchian mesoeucrocodylian crocodylomorphs. Fossils have been found in Europe (Denmark, England, France, Germany, Spain and Sweden), Africa (Algeria, Niger, Mali, Morocco and Tunisia), North America (Canada and the United States) and South America (Brazil and Uruguay). The pholidosaurids first appeared in the fossil record during the Bathonian stage of the Middle Jurassic. Jouve & Jalil (2020) described postcranial material of a pholidosaurid from the Paleocene (Danian) of Ouled Abdoun Basin (Morocco), representing the most recent record of the family. The authors also reinterpreted putative Maastrichtian dyrosaurid ''Sabinosuchus'' as a pholidosaurid, and argued that at least two independent pholidosaurid lineages reached the Maastrichtian, among which one survived the Cretaceous–Paleogene extinction event. Before the publication of this study it was thought that the family became extinct during the Late Turonian stage of the La ...

Peirosauridae
Peirosauridae is a Gondwanan family of mesoeucrocodylians that lived during the Cretaceous period. It was a clade of terrestrial crocodyliforms that evolved a rather dog-like form, and were terrestrial carnivores. It was phylogenetically defined in 2004 as the most recent common ancestor of ''Peirosaurus'' and Lomasuchinae and all of its descendants. Lomasuchinae is a subfamily of peirosaurids that includes the genus ''Lomasuchus''. Lomasuchinae was defined in the same 2004 study as the most recent common ancestor of ''Lomasuchus'' and Mahajangasuchini and all of its descendants. Mahajangasuchini, also constructed in the study, was defined as the most recent common ancestor of ''Mahajangasuchus'' and ''Uberabasuchus'' and all of its descendants. However, all more recent phylogenetic analyses placed ''Mahajangasuchus'' within its own family, Mahajangasuchidae, along with the newly named ''Kaprosuchus''.

Antaeusuchus
''Antaeusuchus taouzensis'' is a species of peirosaurid notosuchian from the Late Cretaceous Kem Kem Group of Morocco. It was described in 2021, and it is the only species in the genus ''Antaeusuchus''. It is the fourth notosuchian described from the region and the second Kem Kem peirosaurid after ''Hamadasuchus''. Discovery and naming ''Antaeusuchus'' is known from two specimens: the holotype NHMUK PV R36829, consisting of paired mandibles, and the paratype NHMUK PV R36874, a partial right mandible. Both specimens were commercially collected and recovered from unspecified beds of the Kem Kem Group near Jebel Beg'aa, Taouz township in the Errachidia Province of Morocco. Both fossils are preserved without distortion and in good condition, with damage mostly restricted to the teeth. The generic name derives from Antaeus, a giant from Greek and Berber mythology said to be buried in northern Morocco and the Ancient Greek σοῦχος, soukhos meaning crocodile. The species name refe ...

Araripesuchus Buitreraensis
''Araripesuchus'' is a genus of extinct crocodyliform that existed during the Cretaceous period of the late Mesozoic era some 125 to 66 million years ago. Six species of ''Araripesuchus'' are currently known. They are generally considered to be notosuchians (belonging to the clade Mesoeucrocodylia), characterized by their varied teeth types and distinct skull elements. This genus consists of six species: ''A. buitreraensis'', discovered in Argentina, ''A. wegeneri'', discovered in Cameroon and Niger, ''A. rattoides'', discovered in Niger, ''A. tsangatsangana'', discovered in Madagascar, ''A. gomesii'' (the type species), discovered in Brazil and another species discovered in Argentina, ''A. patagonicus''. Description Its length was about with a weight of . ''Araripesuchus'' can be distinguished by their laterally bulged edges of the snout, with the bulge being the most prominent around the area of an enlarged maxillary tooth. The snout and premaxilla are also smoother than that o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
