The Early Evolution of Rhynchosaurs
(Frontiers, 2016-01)
The rhynchosaurian archosauromorphs are an important and diverse group of fossil tetrapods that first appeared during the Early Triassic and probably became extinct during the early Late Triassic (early Norian). Here, the ...
The oldest rhynchosaur from Argentina: a Middle Triassic rhynchosaurid from the Chañares Formation (Ischigualasto-Villa Unión Basin, La Rioja Province)
(Springer Heidelberg, 2013-09)
Rhynchosaurs first appear in the Early Triassic fossil record and flourished during the late Carnian as the dominant members of several assemblages worldwide. In Argentina, the rhynchosaur record is currently restricted ...
Eifelosaurus triadicus Jaekel, 1904, a “forgotten” reptile from the Upper Buntsandstein (Triassic: Anisian) of the Eifel region, Germany
(Springer Heidelberg, 2021-12)
We provide a detailed description of the poorly known reptile Eifelosaurus triadicus Jaekel, 1904 from the Upper Buntsandstein (Triassic: early Anisian) of Oberbettingen in the southwestern Eifel region of Rhineland-Palatinate, ...
The rhynchosaur record, including a new stenaulorhynchine taxon, from the Chañares Formation (upper Ladinian–?lowermost Carnian levels) of La Rioja Province, north-western Argentina
(Taylor & Francis, 2021-01-22)
Rhynchosaurs were quadrupedal, bulky herbivorous archosauromorph diapsids with a highly specialized dental apparatus. This group is restricted to the Triassic Period and became extremely abundant worldwide during the late ...
Reconstruction of the Masticatory Apparatus of the Holotype of the Rhynchosaur Hyperodapedon sanjuanensis from the Late Triassic of Argentina: Implications for the Diagnosis of the Species
(Asociación Paleontológica Argentina, 2018-05)
Rhynchosaurs are a clade of robust, quadruped, and herbivorous stem-archosauromorph diapsids restricted to the Triassic Period. Most species have a specialized masticatory apparatus composed of a blade-and-groove occlusion ...
A new rhynchosaur maxillary tooth plate morphotype expands the disparity of the group in the Ischigualasto Formation (Late Triassic) of Northwestern Argentina
(Taylor & Francis Ltd, 2018-02)
Rhynchosaurs are a clade of quadruped, herbivorous stem-archosaur diapsids restricted to the Triassic Period. The group became globally distributed and the numerically dominant tetrapods of several terrestrial ecosystems ...
The anatomy and phylogenetic position of the erythrosuchid archosauriform Guchengosuchus shiguaiensis from the earliest Middle Triassic of China
(PeerJ Inc, 2019-02)
Erythrosuchidae is a clade of early archosauriform reptiles, which were apex predators in many late Early and Middle Triassic ecosystems, following the Permo-Triassic mass extinction. Erythrosuchids had a worldwide ...
The phylogenetic relationships of basal archosauromorphs, with an emphasis on the systematics of proterosuchian archosauriforms
(PeerJ, 2016-04)
The early evolution of archosauromorphs during the Permo-Triassic constitutes an excellent empirical case study to shed light on evolutionary radiations in deep time and the timing and processes of recovery of terrestrial ...
Archosauromorph remains from the Tarjados Formation (Early-Middle Triassic, NW Argentina)Restos de un Arcosauromorfo de la Formación Tarjados (Triásico temprano–medio, NO Argentina)
(Asociacion Paleontologica Argentina, 2015-10)
The Agua de la Peña Group of the Ischigualasto-Villa Unión Basin (northwestern Argentina) documents the evolution of archosauromorph assemblages in western Gondwana during the late Middle and Late Triassic. However, the ...
Redescription and phylogenetic relationships of the proterochampsid Rhadinosuchus gracilis (Diapsida: Archosauriformes) from the early Late Triassic of Southern BrazilRedescripción y relaciones filogenéticas del proterochámpsido Rhadinosuchus gracilis (Diapsida: Archosauriformes) del Triásico tardío temprano del sur de Brasil
(Asociación Paleontológica Argentina, 2015-08-01)
The proterochampsids are small to medium-sized, quadrupedal and probable semi-aquatic reptiles that were part of the evolutionary radiation of Archosauromorpha during the Triassic. The group is restricted to the Middle and ...
