Peirosaurids
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''.

Hamadasuchus Rebouli
''Hamadasuchus'' is an extinct genus of sebecian Crocodylomorpha, crocodylomorph. Fossils have been found from the Kem Kem Formation outcropping in southeastern Morocco. These beds date back to the Albian and Cenomanian stages of the Late Cretaceous. It was first assigned to the family (biology), family Trematochampsidae. Diagnostic features of the genus include its lateromedially compressed and serrated teeth. It was deep-snouted and had a slightly heterodont dentition with three distinct tooth morphologies present from sections of the lower jaw.Larsson, H. C. E. and Christian Sidor, Sidor, C. A. (1999).

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 ...

Montealtosuchus
''Montealtosuchus'' was an extinct genus of terrestrial crocodyliform.C. F. C. Geroto and R. J. Bertini. (2019). New material of ''Pepesuchus'' (Crocodyliformes; Mesoeucrocodylia) from the Bauru Group: implications about its phylogeny and the age of the Adamantina Formation. ''Zoological Journal of the Linnean Society'' 185(2):312-334 It was discovered in 2004 in the Bauru Basin of Brazil, from Campanian-Maastrichtian deposits of the Adamantina Formation. The species was described in 2007, and assigned to the family Peirosauridae. The type species is ''M. arrudacamposi''. The genus takes its name from the type locality in Monte Alto municipality. This fossil, which was found in 2004, near the town of Monte Alto, in São Paulo state is very well preserved and quite complete. Most importantly, skull material has been found and this can help to link this fossil specimen with today's modern crocodiles. It would have grown to about 2 metres in length and would have been an active p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It is known only from the holotype MOZ 4084 PV which was found in the Loma de la Lata locality of the Neuquén Province, Patagonia. It was originally reported as collected from sediments of the Rio Colorado Subgroup, Neuquén Group. Later, Hugo and Leanza (2001) noted that this specimen was actually collected from the underlying Portezuelo Formation of the Rio Neuquén Subgroup, Neuquén Group. More recent stratigraphic work on this area identified that horizon as belonging to the younger, Coniacian-age, Plottier Formation of the R ...

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 ...

Patagosuchus
''Patagosuchus'' is an extinct genus of peirosaurid crocodyliform known from the early Late Cretaceous Portezuelo Formation of Neuquén Province, western central Argentina. It contains a single species, ''Patagosuchus anielensis''. It is distinguished from other peirosaurids by its extremely heterodont dentition, which includes small serrated teeth at the front of the jaws with much larger, laterally compressed caniniform teeth behind them. ''Patagosuchus'' also has large spaces between its teeth called interalveolar spaces that are not found in any other peirosaurid. Discovery ''Patagosuchus'' is known solely from its holotype, MANE-PV 1, which consists of some associated bones belonging to a single individual. The remains include a fragmentary left dentary and splenial, the right maxilla and right jugal bone, a back vertebra, a back osteoderm and the right humerus.

Phylogenetically
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An unrooted tree diagram (a network) makes no assumption about the ancestral line, and does n ...
