Gasparinisuchus
''Gasparinisuchus'' is an extinct genus of peirosaurid notosuchian known from the Late Cretaceous (Santonian to early Campanian stage) of Neuquén and Mendoza Provinces, western central Argentina. It contains a single species, ''Gasparinisuchus peirosauroides''. Discovery ''Gasparinisuchus'' is known only from two individuals. The holotype MOZ 1750 PV represented by partial skull and lower jaws with teeth and various associated postcranial skeleton including vertebrae and dermal plates which are currently missing. It was originally described by Gasparini (1982) and Gasparini ''et al.'' (1991) and referred to '' Peirosaurus torminni''. MOZ 1750 PV 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 Neuqu� ...

Peirosaurus Torminni
''Peirosaurus'' is an extinct genus of peirosaurid crocodylomorph known from the Late Cretaceous period (late Maastrichtian stage) of Minas Gerais, southern Brazil. It contains a single species, ''Peirosaurus torminni''. It is the type genus of the family Peirosauridae. Discovery ''Peirosaurus'' is known from the holotype DGM 433-R, fragmentary skull (left premaxilla bearing five teeth, isolated maxillary and dentary teeth and left palpebral bone) and partial postcranial skeleton including radius, ulna, left pubis and ischium, some presacral and a single caudal vertebrae, ribs, haemal arches and dermal plates. It was collected by Llewellyn Ivor Price in 1947-1949 at the Price Quarry 3, Peirópolis Site near Uberaba, in the Serra de Galga Member of the Marília Formation (Bauru Group), dating to the late Maastrichtian stage of the Late Cretaceous, about 68-66 million years ago.

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''.

Anacleto Formation
The Anacleto Formation is a geologic formation with outcrops in the Argentine Patagonian provinces of Mendoza, Río Negro, and Neuquén. It is the youngest formation within the Neuquén Group and belongs to the Río Colorado Subgroup. Formerly that subgroup was treated as a formation, and the Anacleto Formation was known as the Anacleto Member. The type locality of this formation lies west of the city of Neuquén. At its base, the Anacleto Formation conformably overlies the Bajo de la Carpa Formation, also of the Río Colorado Subgroup, and it is in turn unconformably overlain by the Allen Formation of the younger Malargüe Group. The Anacleto Formation varies between thick, and consists mainly of claystones and mudstones, purple and dark red in color, deposited in fluvial, lacustrine and floodplain environments. Geodes are often found scattered throughout this formation. Fossil content The following animals are known from bones found in the Anacleto Formation: * s ...

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 under ... [...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 ...

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

Neuquén Group
The Neuquén Group is a group of geologic formations found in Argentina. Rocks in the Neuquén Group fall within the Cenomanian to early Campanian stages of the Late Cretaceous Period. It overlies the older Lohan Cura Formation and is itself overlain by the younger Allen Formation of the Malargüe Group, separated from both by unconformities, dated to 98 and 79 Ma respectively.Leanza et al., 2004, p.63 Description Deposits have been located in the provinces of Río Negro, Neuquén, and Mendoza. Although several different types of environments are represented in various sections of the Neuquén Group, the dominant regime is alluvial deposition. Many dinosaur and other fossil types have been discovered in these sediments. Subdivision There are seven formations within the Neuquén Group. These are divided into three subgroups named after major rivers in the area. In some works, the subgroups themselves are treated as formations and what usually is considered to be the formatio ...

Coniacian
The Coniacian is an age or stage in the geologic timescale. It is a subdivision of the Late Cretaceous Epoch or Upper Cretaceous Series and spans the time between 89.8 ± 1 Ma and 86.3 ± 0.7 Ma (million years ago). The Coniacian is preceded by the Turonian and followed by the Santonian. Stratigraphic definitions The Coniacian is named after the city of Cognac in the French region of Saintonge. It was first defined by French geologist Henri Coquand in 1857. The base of the Coniacian Stage is at the first appearance of the inoceramid bivalve species '' Cremnoceramus deformis erectus''. The official reference profile for the base (a GSSP) is located in Salzgitter-Salder, Lower Saxony, Germany. The top of the Coniacian (the base of the Santonian Stage) is defined by the appearance of the inoceramid bivalve '' Cladoceramus undulatoplicatus''. The Coniacian overlaps the regional Emscherian Stage of Germany, which is roughly coeval with the Coniacian and Santonian Stages. In ...
