A new stahleckeriid dicynodont record from the late Ladinian-?early Carnian levels of the Chañares Formation (Ischigualasto-Villa Unión Basin) of northwestern Argentina [PDF]
, 2021 The kannemeyeriiforms of the latest Ladinian-?early Carnian Chañares Formation (Ischigualasto-Villa Unión Basin) exemplify the historical taxonomic controversies of several South Am erican dicynodonts. Three taxa were originally recognized based on skull

Journal of Vertebrate Paleontology, 2015 Cryptodont dicynodonts are some of the most abundant therapsid taxa in the upper Permian fossil record. Despite extensive taxonomic study of these families, the species diversity of geikiid cryptodonts remains problematic, particularly for the set of edentulous taxa in the genera Pelanomodon, Propelanomodon, and Geikia.

The paleoclimatic context for South American Triassic vertebrate evolution [PDF]
, 2021 The Triassic Period was the setting for the origin and early diversification of Mesozoic ecosystems after the end-Permian mass extinction. The study of the Triassic is essential to understand the evolution of non-marine Mesozoic ecosystems, particularly ...

Frontiers in Earth ScienceThe Dicynodontia (Therapsida: Anomodontia) is one of the most successful Permo-Triassic terrestrial tetrapod clades and the oldest specimens are recorded from the middle Permian Eodicynodon Assemblage Zone of South Africa. Their fossil record is abundant

EVOLUTIONARY TRENDS IN TRIASSIC DICYNODONTIA [PDF]
, 1974 Triassic Dicynodontia differ from most of their Permian ancestors in a number of specialisations that reach extremes in the Upper Triassic. These are ( 1) increase in total body size, (2) increase in the relative length of the snout and secondary ...

The Anatomical Record, EarlyView.Abstract Dicynodonts (Anomodontia: Dicynodontia) were one of the main groups of terrestrial tetrapods in Permian and Triassic faunas. In Brazil, the genus Dinodontosaurus is one of the most common tetrapod taxon in the Triassic Santa Maria Supersequence. This genus has a complex taxonomic history and is represented in the Triassic of both Argentina and

Implications of astronomical climate cycles to the chronology of the Triassic [PDF]
, 2000 A high resolution climate record from a thick, continuous sedimentary sequence in the Newark basin provides the basis for an astronomically calibrated time scale for the Late Triassic.

The Anatomical Record, EarlyView.Abstract Last year, we challenged the view that large‐bodied theropod dinosaurs such as Tyrannosaurus rex resembled primates in cognition and behavior, a proposition made by Herculano‐Houzel in 2023. More recently, Jensen et al. have criticized our work on this topic, raising methodological and conceptual issues.

Feeding adaptations in Triassic Dicynodonts [PDF]
, 1978 Main articleThe Dicynodontia declined markedly at the close of the Permian, entered the Triassic with very few species and had a final burst of evolutionary success in the Middle Triassic, before being overcome by archosaurian competitors in the Upper ...

Dicynodont (Therapsida) bone histology: phylogenetic and physiological implications [PDF]
, 1993 The bone histology of humeri of a number of taxonomically well established and easily definable dicynodont genera is described and compared. The bone of Aulacephalodon, Cistecephalus, Dicynodon, Endothiodon, Lystrosaurus, Kannemeyeria and Oudenodon ...
