ABSTRACT Permian dicynodonts were discovered in strata exposed on the flanks of the Bogda Mountains (Xinjiang, China) in 1928. Nearly all known specimens were collected in the Guodikeng Formation (= upper Wutonggou low-order cycle); the single exception is the holotype of Kunpania scopulusa, which originated in the underlying Quanzijie Formation. The Quanzijie Formation is generally considered Capitanian in age, which would make Kunpania one of the oldest known bidentalian dicynodonts, but the…

The evolution of the synapsid tusk: insights from dicynodont therapsid tusk histology
TLDR
The evolution of an ever-growing dentition, such as a tusk, is predicated on the evolution of significantly reduced tooth replacement and a permanent soft-tissue attachment, which helps to explain why tusks are restricted to this clade among extant vertebrates.
Histology and μCT reveal the unique evolution and development of multiple tooth rows in the synapsid Endothiodon
TLDR
A model of multiple tooth row development in E. bathystoma is presented in which labial migration of functional teeth was extensive enough to prevent resorption and replacement by newer generations of teeth, representing another mechanism by which multiple tooth rows evolved in amniotes.

A New Dicynodont (Therapsida: Anomodontia) from the Permian of Southern Brazil and Its Implications for Bidentalian Origins
TLDR
Phylogenetic analysis indicates that R. procurvidens is the earliest and most basal member of Bidentalia, a cosmopolitan clade that includes Permian and Triassic dicynodonts whose dentition is usually reduced to a pair of maxillary tusks.

ABSTRACT Recently, Repelinosaurus robustus from Laos was proposed as the basal-most member of Kannemeyeriiformes and regarded as Early Triassic in age. A new dicynodont specimen from the Sunjiagou
Distinctive Emydopoid Dicynodont (Therapsida, Anomodontia) Mandibles from the Permian Ruhuhu and Usili Formations (Songea Group), Ruhuhu Basin, Tanzania
ABSTRACT Dicynodont therapsids were discovered in the Permian Usili Formation (Ruhuhu Basin, Tanzania) in the 1930s and in the Permian Ruhuhu Formation in the 1960s, with further collections being
NEW SPECIMENS OF THE TANZANIAN DICYNODONT “CRYPTOCYNODON PARRINGTONI” VON HUENE, 1942 (THERAPSIDA, ANOMODONTIA), WITH AN EXPANDED ANALYSIS OF PERMIAN DICYNODONT PHYLOGENY
Abstract The dicynodont species “Cryptocynodon” parringtoni von Huene, 1942 was described from a single poorly preserved specimen collected from the Upper Permian Kawinga Formation, Ruhuhu Basin,
New Materials of the Enigmatic Dicynodont Abajudon kaayai (Therapsida, Anomodontia) from the Lower Madumabisa Mudstone Formation, Middle Permian of Zambia
ABSTRACT Dicynodonts were one of the most diverse and abundant clades of tetrapods from the Lopingian (late Permian) to the Late Triassic. Despite their ecological and biostratigraphic importance,
A new tusked cistecephalid dicynodont (Therapsida, Anomodontia) from the upper Permian upper Madumabisa Mudstone Formation, Luangwa Basin, Zambia
TLDR
Increased knowledge of cistecephalid diversity shows that they vary in functionally relevant characters, such as degree of inflation of the bony vestibule and the morphology of the scapula and humerus, indicating the need for a more nuanced approach to the relationship between form, function and ecology in the clade.
Sungeodon kimkraemerae n. gen. n. sp., the oldest kannemeyeriiform (Therapsida, Dicynodontia) and its implications for the early diversification of large herbivores after the P/T boundary
The dicynodont Sungeodon kimkraemerae n. gen. n. sp. is described on the basis of a skull from the Lower Triassic Jiucaiyuan Formation of Dalongkou (Junggar Basin, Xinjiang Uygur Autonomous Region,
The cranial anatomy of Kombuisia frerensis Hotton (Synapsida, Dicynodontia) and a new phylogeny of anomodont therapsids
TLDR
The general topology of this phylogeny supports the main aspects of recent hypotheses of anomodont relationships, and not only resolves critical nodes at the base of the Dicynodontia that were previously obscured by polytomies, but also introduces new hypotheses of relationships.
The Permian Dicynodont Colobodectes cluveri (Therapsida, Anomodontia), with Notes on Its Ontogeny and Stratigraphic Range in the Karoo Basin, South Africa
ABSTRACT The dicynodont Colobodectes cluveri was described from a single specimen in 2003. Although the holotype possessed a distinctive combination of primitive, derived, and autapomorphic
REDESCRIPTION, PHYLOGENETIC POSITION, AND STRATIGRAPHIC SIGNIFICANCE OF THE DICYNODONT GENUS ODONTOCYCLOPS (SYNAPSIDA: ANOMODONTIA)
TLDR
Cladistic analysis of a data set including Odontocyclops and 18 other well-known South African dicynodont genera does not support the hypothesis that Odontocryclops is a close relative of Dicynodon or of Triassic dicYNodonts such as Kannemeyeria, and a close relationship with Oudenodon and Rhachiocephalus is proposed.
