2024 In Archosaur Paleontology
This article records new taxa of every kind of fossil archosaur that are scheduled to be Species description, described during 2024, as well as other significant discoveries and events related to the paleontology of archosaurs that will be published in 2024. Pseudosuchians New pseudosuchian taxa General pseudosuchian research * Sennikov (2024) interprets Ornithosuchidae, ornithosuchids as macrophagous predators with specialized jaw apparatus, and notes analogs between them and saber-toothed therapsids (including mammals). * A study on the locomotion of ''Riojasuchus, Riojasuchus tenuisceps'' is published by von Baczko ''et al.'' (2024), who reconstruct ''R. tenuisceps'' as having an erect posture and parasagittal gait, but do not conclusively resolve whether it was bipedal or quadrupedal. * A study on the anatomy of the skull and on the neurology of ''Tarjadia, Tarjadia ruthae'' is published by Desojo ''et al.'' (2024). * A study on the humeral bone histology of ''Bengg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poposauroidea
Poposauroidea is a clade of advanced pseudosuchians (archosaurs closer to crocodilians than to dinosaurs). It includes poposaurids, shuvosaurids, ctenosauriscids, and other unusual pseudosuchians such as ''Qianosuchus'' and '' Lotosaurus''. However, it excludes most large predatory quadrupedal " rauisuchians" such as rauisuchids and " prestosuchids". Those reptiles are now allied with crocodylomorphs (crocodile ancestors) in a clade known as Loricata, which is the sister taxon to the poposauroids in the clade Paracrocodylomorpha. Although it was first formally defined in 2007, the name "Poposauroidea" has been used for many years. The group has been referred to as Poposauridae by some authors, although this name is often used more narrowly to refer to the family that includes ''Poposaurus'' and its close relatives. Poposauroids went extinct at the end of the Triassic period along with other non-crocodylomorph pseudosuchians. However, they were among the most diverse and lon ...

Gracilisuchidae
Gracilisuchidae is an extinct family of suchian archosaurs known from the early Middle Triassic to the early Late Triassic (Anisian – early Carnian) of China and Argentina. Distribution Currently, the oldest known gracilisuchid is ''Turfanosuchus dabanensis'' from the Anisian stage of Xinjiang, China. Two gracilisuchids are known from the Ladinian or early Carnian stage, '' Gracilisuchus stipanicicorum'' and '' Yonghesuchus sangbiensis'', from La Rioja Province of Argentina, and Shanxi, respectively. These species were considered enigmatic prior to the recognition of the family in 2014, suggesting a rapid phylogenetic diversification of archosaurs by the Middle Triassic. This radiation is a part of the broader recovery of terrestrial ecosystems after the Permian–Triassic extinction event. Gracilisuchids are known from approximately similar northern and southern mid-palaeolatitudes, demonstrating a wide distribution of early archosaurs over much or all of Pangaea by the ear ...

Parvosuchus
''Parvosuchus'' (meaning "small crocodile") is an extinct genus of gracilisuchid pseudosuchians from the Middle Triassic, Middle–Late Triassic Santa Maria Formation (Paraná Basin) of Brazil. The genus contains a Monotypic taxon, single species, ''P. aurelioi'', known from a cranium and partial skeleton. Discovery and naming The ''Parvosuchus'' holotype specimen, CAPPA/Federal University of Santa Maria, UFSM 0412, was discovered at the Linha Várzea 2 site in the Pinheiros-Chiniquá Sequence, which belongs to the Santa Maria Formation of the Santa Maria Supersequence (Paraná Basin) in Paraíso do Sul municipality of Rio Grande do Sul state, Brazil. This locality represents the ''Dinodontosaurus'' Assemblage Zone. The specimen consists of a largely Joint, articulated skeleton, including the skull and lower jaws, the last 11 dorsal vertebrae, two sacral vertebrae, a pelvic girdle, part of the right femur, and a partial left hindlimb (comprising pieces of the femur, tibia, fib ...
