Maehary
''Maehary'' (meaning "one who looks to the sky" in Guaraní) is a genus of pterosauromorph from the Late Triassic (Norian) Caturrita Formation of Rio Grande do Sul, Brazil. The genus contains a single species, ''M. bonapartei'', known from a partial skull and fragmentary postcrania. Discovery and naming The ''Maehary'' holotype specimen, CAPPA/UFSM 0300, was discovered sometime between 2002 and 2005 in layers of the Caturrita Formation (Linha São Luiz Site, Candelária Sequence, Santa Maria Supersequence) near Faxinal do Soturno, Rio Grande do Sul, Brazil. The holotype consists of a partial skull, vertebral centra, and fragmentary scapula. Another specimen has also been assigned to the genus, UFRGS-PV-0769-T, which consists of a left maxilla and was previously referred to '' Faxinalipterus''. The specimen was originally described in 2010 as belonging to the supposed basal pterosaur '' Faxinalipterus''.J. F. Bonaparte, C. L. Schultz, and M. B. Soares. (2010). Pterosauria from ...

Pterosauromorpha
Pterosauromorpha (meaning "pterosaur-like forms") is one of the two basic divisions of Ornithodira that includes pterosaurs and all taxa that are closer to them than to dinosaurs and their close relatives (i.e. Dinosauromorpha). In addition to pterosaurs, Pterosauromorpha also includes the basal clade Lagerpetidae and some other Late Triassic ornithodirans ('' Maehary'' and '' Scleromochlus''). Classification The name Pterosauromorpha was originally coined by Emil Kuhn-Schnyder and Hans Rieber (1986) for a reptilian subclass distinct from Archosauria which includes pterosaurs. In 1997, Kevin Padian classified Pterosauromorpha as a clade of archosaurs and proposed phylogenetic definition for this group: "Pterosauria and all ornithodiran archosaurs closer to them than to dinosaurs". Brian Andres and Kevin Padian redefined Pterosauromorpha as: "The clade consisting of ''Pterodactylus'' (originally ''Ornithocephalus'') ''antiquus'' (Sömmerring 1812) (Pterosauria) and all org ...

Caturrita Formation
The Caturrita Formation is a geological formation, rock formation found in Rio Grande do Sul, Brazil. Its sediments were deposited in the Paraná Basin. The formation is from the Upper Triassic and forms part of the Santa Maria Supersequence in the upper section of the Rosário do Sul Group. Etymology The formation received this name, because Caturrita is a neighbourhood (barrio) of Santa Maria, Rio Grande do Sul, Santa Maria. In Portuguese ''caturrita'' also refers to the monk parakeet. Stratigraphy The sediments of the Caturrita Formation belong to the second unit of the Santa Maria Supersequence and overlie the Alemoa Member of the Santa Maria Formation. The clayey sediments of the Alemoa Member gradually give way to the more sandy, rarely conglomeratic, Caturrita Formation, which finishes with an unconformity. After this erosional event follow the Rhaetian sediments of the Mata Sandstone, the third unit of the Santa Maria Supersequence. The Caturrita Formation was once re ...

Faxinalipterus
''Faxinalipterus'' is a genus of ornithodiran archosaur, originally described as a pterosaur, from the Late Triassic Caturrita Formation of southern Brazil. A study from 2022 reinterpreted the fossil remains and instead suggests them to belong to a member of the Lagerpetidae, a more basal clade of pterosauromorph. Description The type species, ''Faxinalipterus minima'' was named and described in 2010 by José Fernando Bonaparte, Marina Bento Soares and César Leandro Schultz. The generic name is derived from Faxinal do Soturno and a Latinised Greek ''pteron'', "wing". The specific name, from Latin ''minima'', means "smallest". The name was later amended and changed to ''minimus'' in accordance with the rules of the International Commission on Zoological Nomenclature (ICZN). Fossils of the species were found in 2002 and 2005 at a site 1.5 kilometres northeast of Faxinal do Soturno, Rio Grande do Sul, from the Caturrita Formation dating from the Carnian-Norian, 220–215 m ...

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 ...

Guarani-Kaiowá
Guarani-Kaiowás () are an indigenous people of Paraguay, the Brazilian state of Mato Grosso do Sul and northeastern Argentina. In Brazil, they inhabit Ñande Ru Marangatu, an area of tropical rainforest. This was declared a reservation in October 2004. Marcos Verón, a leader of this people was beaten to death in January 2003. They are one of the three Guaraní sub-groups (the others are Ñandeva and Mbya). They mainly live in the Brazilian state of Mato Grosso do Sul. It is estimated that more than 30,000 Guaranis live in Brazil. In Paraguay they number about 40,000. The Guaraní language is one of the official languages of Paraguay, alongside the Spanish language. Name The Guarani-Kaiowá are also known as the Kaiwá, Caingua, Caiua, Caiwa, Cayua, Kaiova, and Kayova. These spellings were largely devised by Europeans, The National Museum of Brazil (Portuguese: Museu Nacional) keeps records of the earliest Latinized forms for transcribing the name on behalf of the people, c ...

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 ...

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 ...

José Bonaparte
José Fernando Bonaparte (14 June 1928 – 18 February 2020) was an Argentine paleontologist who discovered a plethora of South American dinosaurs and mentored a new generation of Argentine paleontologists . One of the best-known Argentine paleontologists, he has been described by paleontologist Peter Dodson as "almost singlehandedly ... responsible for Argentina becoming the sixth country in the world in kinds of dinosaurs". Biography Bonaparte was the son of an Italian sailor, with no close connection to Napoleon's House of Bonaparte. He was born in Rosario, Santa Fe, Argentina, and grew up in Mercedes, Buenos Aires. Despite a lack of formal training in paleontology, he started collecting fossils with many friends at an early age, and created a museum in their home town. He later became the curator of the National University of Tucumán, where he was named ''Doctor Honoris causa'' in 1976, and then in the late 1970s became a senior scientist at the Museo Argentino de Cienci ...

Phylogenetics
In biology, phylogenetics (; from Greek language, Greek wikt:φυλή, φυλή/wikt:φῦλον, 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, protein Amino acid, amino acid sequences, or Morphology (biology), 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 un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
