Lomasuchus
''Lomasuchus'' is an extinct genus of peirosaurid notosuchian known from the Late Cretaceous (Santonian stage) of Neuquén Province, western central Argentina. It contains a single species, ''Lomasuchus palpebrosus''. Gasparini, Z., Chiappe, L. M. and Fernandez, M. (1991). A new Senonian peirosaurid (Crocodylomorpha) from Argentina and a synopsis of the South American Cretaceous crocodilians. ''Journal of Vertebrate Paleontology'' 11:316-333. 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 ...

Peirosaurid
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''.

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] |
Bajo De La Carpa Formation
The Bajo de la Carpa Formation is a geologic formation of the Neuquén Basin that crops out in northern Patagonia, in the provinces of Río Negro and Neuquén, Argentina. It is the oldest of two formations belonging to the Río Colorado Subgroup within the Neuquén Group. Formerly, that subgroup was treated as a formation, and the Bajo de la Carpa Formation was known as the Bajo de la Carpa Member.Sánchez ''et al.'', 2006 At its base, this formation conformably overlies the Plottier Formation of the older Río Neuquén Subgroup, and it is in turn overlain by the Anacleto Formation, the youngest and uppermost formation of the Neuquén Group. The Bajo de la Carpa Formation can reach in thickness in some locations, and consists mainly of sandstones of various colors, all of fluvial origin, with thin layers of mudstone and siltstone in between. Geological features such as geodes, chemical nodules, impressions of raindrops, and paleosols (fossil soils) are commonly found in this ...

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Australia and Ant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plottier Formation
The Plottier Formation is a geologic formation that outcrops in the Argentine Patagonian provinces of Río Negro and Neuquén. It is the younger of two formations belonging to the Río Neuquén Subgroup within the Neuquén Group of the Neuquén Basin, with the oldest rocks dating from the late Coniacian and its youngest maybe from the very start of the Santonian. Formerly, that subgroup was treated as a formation, and the Plottier Formation was known as the Plottier Member.Sánchez ''et al.'', 2006 Description A section near the Neuquén City airport, north of the town of Plottier, is the type locality of the Plottier Formation. At its base, this formation grades into the Portezuelo Formation, and it is in turn overlain conformably by the Bajo de la Carpa Formation, a unit of the Río Colorado Subgroup. The Plottier Formation is the thinnest formation within the Neuquén Group, with a maximum thickness of only . It is differentiated from the underlying Portezuelo Formation pr ...

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.

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
