Puercosuchus
''Puercosuchus'' is an extinct genus of azendohsauridae, azendohsaurid archosauromorph from the Blue Mesa Member of the Chinle Formation in Arizona. The genus contains a Monotypic taxon, single species, ''Puercosuchus traverorum'', known from a bonebed of at least eight individuals. Discovery and naming The ''Puercosuchus'' holotype, Petrified Forest National Park, PEFO 43914, was discovered by a group of Girl Scouts of the USA, Girl Scouts in 2014, and since then, over 900 skeletal remains have been recovered from at least eight individuals.

Azendohsauridae
Azendohsauridae is a family of allokotosaurian archosauromorphs that lived during the Middle to Late Triassic period, around 242-216 million years ago. The family was originally named solely for the eponymous ''Azendohsaurus'', marking out its distinctiveness from other allokotosaurs, but the family now includes four other genera: the basal genus '' Pamelaria'', the large horned herbivore '' Shringasaurus'', and two carnivorous genera grouped into the subfamily-level subclade Malerisaurinae, '' Malerisaurus'' and '' Puercosuchus'', and potentially also the dubious genus ''Otischalkia''. Most fossils of azendohsaurids have a Gondwanan distribution, with multiple species known across Morocco and Madagascar in Africa as well as India, although fossils of malerisaurine azendohsaurids have also been found in the southwestern United States of North America. Azendohsaurids are notable for the various dinosaur-like traits found in some species, including the sauropodomorph-like nec ...

Late Triassic
The Late Triassic is the third and final epoch (geology), epoch of the Triassic geologic time scale, Period in the geologic time scale, spanning the time between annum, Ma and Ma (million years ago). It is preceded by the Middle Triassic Epoch and followed by the Early Jurassic Epoch. The corresponding series (stratigraphy), series of rock beds is known as the Upper Triassic. The Late Triassic is divided into the Carnian, Norian and Rhaetian Geologic time scale, Ages. Many of the first dinosaurs evolved during the Late Triassic, including ''Plateosaurus'', ''Coelophysis'', and ''Eoraptor''. The Triassic–Jurassic extinction event began during this epoch and is one of the five major mass extinction events of the Earth. Etymology The Triassic was named in 1834 by Friedrich August von Namoh, Friedrich von Alberti, after a succession of three distinct rock layers (Greek meaning 'triad') that are widespread in southern Germany: the lower Buntsandstein (colourful sandstone'')'', t ...

Prehistoric Reptile Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ...

Allokotosaurs
Allokotosauria is a clade of early archosauromorph reptiles from the Middle Triassic, Middle to Late Triassic known from Asia, Africa, North America and Europe. Allokotosauria was first described and named when a new monophyletic grouping of specialized herbivorous archosauromorphs was recovered by Sterling J. Nesbitt, John J. Flynn, Adam C. Pritchard, J. Michael Parrish, Lovasoa Ranivoharimanana and André R. Wyss in 2015 in paleontology, 2015. The name Allokotosauria is derived from Greek language, Greek meaning "strange reptiles" in reference to unexpected grouping of early archosauromorph with a high disparity of features typically associated with herbivore, herbivory. History Nesbitt ''et al.'' (2015) defined the group as a stem-based taxon containing ''Azendohsaurus madagaskarensis'' and ''Trilophosaurus buettneri'' and all taxa more closely related to them than to ''Tanystropheus longobardicus'', ''Proterosuchus fergusi'', ''Protorosaurus speneri'' or ''Rhynchosaurus art ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Puerco River
The Puerco River or Rio Puerco is a tributary of the Little Colorado River in northwestern New Mexico and northeastern Arizona. It flows through arid terrain, including the Painted Desert. Name The Puerco River is sometimes called Rio Puerco of the West, to distinguish it from the Rio Puerco of the East that rises in the same vicinity but flows east to the Rio Grande. Although the word Puerco means ''pig'', it also used to mean dirty or filthy in Spanish, this usage in the southwest United States is better translated as ''Dirty River or Muddy River'' due its high content of silt and mud. Geography The intermittent river is the main tributary of the Little Colorado River, which is a tributary of the Colorado River. It drains an area of about and is long. The river's average discharge is very low, less than in normal years, because its drainage basin is extremely dry. For most of the year, the Puerco River is a braided wash containing little or no water, although large ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ...

Malerisaurus
''Malerisaurus'' is an extinct genus of archosauromorph known from Andhra Pradesh of India and Texas of the USA. Description ''Malerisaurus'' was a medium-sized archosauromorph which averaged 1.2 meters in length. ''Malerisaurus'' is known from the holotype ISIR 150, two articulated and almost complete skeletons which were discovered as the presumable gastric contents of two skeletons of ''Parasuchus hislopi''. It was collected from the Lower Maleri Formation, dating to the late Carnian or early Norian stage of the Late Triassic. ''Malerisaurus robinsonae'' was a small archosauromorph, probably capable of climbing trees and swimming. The skull has some adaptations to a carnivorous diet, but is nevertheless unspecialised and probably more of an insectivore. ''Malerisaurus'', seen as a diapsid skull, shows primitive and advanced facies in its unossified laterosphenoid, absence of antorbital and mandibular fenestrae, gracile form, primitive girdles, elongated cervicals and a ...
