Venetoraptor
''Venetoraptor'' (meaning "Vale Vêneto plunderer") is an extinct genus of lagerpetid archosaurs from the Late Triassic Santa Maria Formation (Paraná Basin) of Rio Grande do Sul, Brazil. The genus contains a single species, ''V. gassenae'', known from a partial skeleton. ''Venetoraptor'' is characterized by the presence of a beak and scythe-like claws on long fingers. Discovery and naming The ''Venetoraptor'' holotype specimen, CAPPA/ UFSM 0356, was discovered in the Santa Maria Formation (''Hyperodapedon'' Assemblage Zone) in the Paraná Basin of São João do Polêsine in Rio Grande do Sul, Brazil. The partially-articulated specimen consists of an incomplete skull, cervical, dorsal, and caudal vertebrae, a partial pelvic girdle, and elements of the arms and legs. In 2023, Müller et al. described ''Venetoraptor gassenae'' as a new genus and species of lagerpetid archosaur based on these fossil remains. The generic name, "''Venetoraptor''", combines a reference to the tou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lagerpetid
Lagerpetidae (; originally Lagerpetonidae) is a family of basal avemetatarsalians (early-diverging members of the reptile lineage leading to birds and other dinosaurs). Though traditionally considered the earliest-diverging dinosauromorphs (archosaurs closer to dinosaurs than to pterosaurs), fossils described in 2020 suggested that lagerpetids are instead an early branch of pterosauromorphs (closer to pterosaurs than to dinosaurs). Lagerpetid fossils are known from the Triassic of San Juan (Argentina), Arizona, New Mexico, and Texas (United States), Rio Grande do Sul (Brazil), and Madagascar. ''Scleromochlus'', a minuscule archosaur from Scotland, is sometimes regarded as a lagerpetid or close relative of the family. Lagerpetids were generally small and lightly-built animals; the largest include '' Dromomeron gigas'' (from Argentina) and an indeterminate ''Dromomeron'' specimen from the Santa Rosa Formation of Texas, reaching a femoral length of . Lagerpetid fossils are rare; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2023 In Archosaur Paleontology
This article records new taxa of every kind of fossil archosaur that were scheduled to be Binomial nomenclature, described during 2023, as well as other significant discoveries and events related to the paleontology of archosaurs that were published in 2023. Pseudosuchians New pseudosuchian taxa General pseudosuchian research * Evidence of the impact of the interplay of abiotic and biotic processes on the evolution of pseudosuchians is presented by Payne ''et al.'' (2023). * A study on the biomechanical properties of the skull of ''Riojasuchus, Riojasuchus tenuisceps'' is published by Taborda, Von Baczko & Desojo (2023), who propose that ''R. tenuisceps'' could have had a wading habit, feeding on small-sizey prey caught from the shoreline. * A study on the bone histology of ''Decuriasuchus, Decuriasuchus quartacolonia'' is published by Farias ''et al.'' (2023), who interpret their findings as indicative of early ontogenetic stage of known specimens, which might have stay ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Maria Formation
The Santa Maria Formation is a sedimentary rock formation found in Rio Grande do Sul, Brazil. It is primarily Carnian in age (Late Triassic), and is notable for its fossils of cynodonts, " rauisuchian" pseudosuchians, and early dinosaurs and other dinosauromorphs, including the herrerasaurid '' Staurikosaurus'', the basal sauropodomorphs '' Buriolestes'' and ''Saturnalia,'' and the lagerpetid '' Ixalerpeton''. The formation is named after the city of Santa Maria in the central region of Rio Grande do Sul, where outcrops were first studied. The Santa Maria Formation makes up the majority of the Santa Maria Supersequence, which extends through the entire Late Triassic. The Santa Maria Supersequence is divided into four geological sequences, separated from each other by short unconformities. The first two of these sequences (Pinheiros-Chiniquá and Santa Cruz sequences) lie entirely within the Santa Maria Formation, while the third (the Candelária sequence) is shared with the ...

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'', ''Herrerasaurus'', 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 ...

Life Restoration
Paleoart (also spelled palaeoart, paleo-art, or paleo art) is any original artistic work that attempts to depict prehistoric life according to scientific evidence. Ansón, Fernández & Ramos (2015) pp. 28–34. Works of paleoart may be representations of fossil remains or imagined depictions of the living creatures and their ecosystems. While paleoart is typically defined as being scientifically informed, it is often the basis of depictions of prehistoric animals in popular culture, which in turn influences public perception of and fuels interest in these organisms. The word paleoart is also used in an informal sense as a name for prehistoric art, most often cave paintings. The term "paleoart"–which is a compound of ''paleo'', the Ancient Greek word for "old", and "art"–was introduced in the late 1980s by Mark Hallett for art that depicts subjects related to paleontology, Hallett (1987) pp. 97–113. but is considered to have originated as a visual tradition in early 1800s ...

Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
