The relationships of the Tritylodontidae (Synapsida)
Zoological Journal of the Linnean Society, 1985From a detailed anatomical survey of the Tritylodontidae, it is possible to examine the phylogenetic status of this taxon of advanced synapsids. The Tritylodontidae are considered to be the sister-group of the Traversodontidae, specifically the Exaerelodon-Massetognathus assemblage, rather than that of the Mammalia plus Tritheledontidae as recently ...

The Phylogenetic Relationships of Eucynodontia (Amniota: Synapsida)
Journal of Mammalian Evolution, 2010The phylogeny of Eucynodontia is an important topic in vertebrate paleontology and is the foundation for understanding the origin of mammals. However, consensus on the phylogeny of Eucynodontia remains elusive. To clarify their interrelationships, a cladistic analysis, based on 145 characters and 31 species, and intergrating most prior works, was ...

The postcranial skeleton of Ennatosaurus tecton (Synapsida, Caseidae)
Journal of Systematic Palaeontology, 2017The postcranial material referable to the Russian caseid Ennatosaurus tecton from the middle Permian is described. Although the cranium has been recently restudied in detail, the descriptions currently available for the postcranial skeleton are essentially limited to the original short account on the holotype provided by Efremov in 1956.

The basicranium of dicynodonts (Synapsida) and its use in phylogenetic analysis
Palaeontology, 2004Current phylogenetic hypotheses for the dicynodonts conflict, probably because the characters used, especially those of the jaws and facial region, show considerable convergence. Characters of the braincase and basipterygoid articulation of the Late Permian–Middle Triassic dicynodonts Diictodon, Dicynodon, Kingoria, Lystrosaurus, Rechnisaurus, and 14 ...

Origin of the Triassic Dicynodonts (Reptilia: Synapsida)
Nature, 1964SO far, workers on the Triassic dicynodonts1–3 have not been able to indicate how this group originated. However, Camp2 has enumerated twelve characters which he thought would be present in their ancestor. Eleven of these characters are found in the Eo-triassic genus Lystrosaurus4.

New Primitive Caseid (Synapsida, Caseasauria) from the Early Permian of Germany
Annals of Carnegie Museum, 2020A new genus and species of a basal synapsid Caseidae, Martensius bromackerensis, is described based on four partial to nearly complete mostly articulated skeletons that provide a comprehensive knowledge of the skeletal morphology. All four specimens were collected from a single site, the Bromacker quarry, in the Lower Permian Artinskian Tambach ...

New evidence of large Permo-Triassic dicynodonts (Synapsida) from Australia
Journal of Vertebrate Paleontology, 2011Dicynodonts are herbivorous synapsids found in Permian and Triassic deposits in all of the Pangean continents. The fossil evidence of this group from Australia is limited to a quadrate, part of a tusk (Thulborn, 1983a, 1990), and a partial femur (Northwood, 1997), all recorded from the earliest Triassic Arcadia Formation in central Queensland ...
