ABSTRACT The description of a new large caseid, Ruthenosaurus russelbrum n. gen., n. sp. from the Early Permian (upper Cisuralian to lower Lopingian) of the Rodez Basin, France, is based on a partial postcranial skeleton that was initially collected at the same time as the holotype of “Cásea” rutena Sigogneau-Russell & Russell, 1974. Despite its distinctly larger size than “C.” rutena, the holotype of Ruthenosaurus n. gen. clearly represents an immature individual, as shown most clearly by the… 
Alierasaurus ronchii, gen. et sp. nov., A Caseid from the Permian of Sardinia, Italy
ABSTRACT A giant caseid, Alierasaurus ronchii, gen. et sp. nov., is herein described, based on a partial postcranial skeleton collected from the Permian Cala del Vino Formation (Alghero, Nurra,
A small caseid synapsid, Arisierpeton simplex gen. et sp. nov., from the early Permian of Oklahoma, with a discussion of synapsid diversity at the classic Richards Spur locality
TLDR
Fragmentary tooth bearing elements and dorsal vertebrae of another small caseid from Richards Spur are described, with a discussion of its significance in the context of caseid evolution, and the continuously expanding faunal list and taxic diversity at this locality.
New material of Alierasaurus ronchii (Synapsida, Caseidae) from the Permian of Sardinia (Italy), and its phylogenetic affinities
New characters of the giant caseid Alierasaurus ronchii are described here based on material recovered from the type locality in the Permian deposits of Cala del Vino Formation (Sardinia NW) and
New Primitive Caseid (Synapsida, Caseasauria) from the Early Permian of Germany
TLDR
A phylogenetic analysis posits the Late Pennsylvanian Eocasea martini Reisz and Fröbisch, 2014, as the basalmost member of the monophyletic Caseidae and the later occurring middle Early Permian Bromacker caseid as the sister taxon of the remaining late Early and Middle Permians members of the clade.
New Postcranial Material of the Early Caseid Casea broilii Williston, 1910 (Synapsida: Caseidae) with a Review of the Evolution of the Sacrum in Paleozoic Non-Mammalian Synapsids
TLDR
It is argued that this repeated acquisition of a three-vertebra sacrum in early synapsids was related to more efficient terrestrial locomotion than to increased weight bearing, suggesting that it was not an adaptation to heavy weight bearing.
A redescription ofOrovenator mayorum(Sauropsida, Diapsida) using high‐resolution μCT, and the consequences for early amniote phylogeny
TLDR
The earliest known neodiapsid Orovenator mayorum from the lower Permian of Oklahoma is redescribed using high‐resolution μCT, revealing remarkable details of the skull anatomy and prompting questions about relationships among early amniotes.
Skull osteology of the holotype of the rhynchosaur Hyperodapedon sanjuanensis (Sill, 1970) from the Upper Triassic Ischigualasto Formation of Argentina.
TLDR
The presence of a pair of septomaxillae in H. sanjuanensis is the first report of these bones in a rhynchosaurid, and this new information allowed to identify septomexillae also in the hyperodapedontines Teyumbaita sulcognathus and H. mariensis.
The postcranial skeleton of Ennatosaurus tecton (Synapsida, Caseidae)
TLDR
The postcranium of Ennatosaurus is informative with respect to both taxonomy and phylogeny, with autapomorphic characters present particularly in the vertebral column, and a 3D photogrammetric model of the mounted specimen at the Paleontological Institute in Moscow forms the basis for a potentially realistic picture of the Russian caseid in life.
Callibrachion and Datheosaurus, Two Historical and Previously Mistaken Basal Caseasaurian Synapsids from Europe
TLDR
New observations on Datheosaurus and Callibrachion provide new insights into the early diversification of caseasaurs, reflecting an evolutionary stage that lacks spatulate teeth and broadened phalanges that are typical for other caseid species.
First arboreal 'pelycosaurs' (Synapsida: Varanopidae) from the early Permian Chemnitz Fossil Lagerstätte, SE Germany, with a review of varanopid phylogeny
TLDR
Systematic results suggest a varanodontine position for Mycterosaurus, the monophyly of South African varanopids including Anningia and the distinction of a skeletal aggregation previously assigned to Heleosaurus, now renamed as Microvaranops parentis gen. et sp.

Cranial Anatomy of Ennatosaurus tecton (Synapsida: Caseidae) from the Middle Permian of Russia and the Evolutionary Relationships of Caseidae
TLDR
Phylogenetic analysis of Caseidae yields a single most parsimonious tree and its topology reveals that the pattern of dental complexity in terms of the number of apical cuspules is homoplasious, cautioning against its use as a unidirectional phylogenetic character.

Eothyris and Oedaleops: Do These Early Permian Synapsids from Texas and New Mexico form a Clade?
TLDR
Although they appear relatively late in synapsid evolution, both eothyridids are significantly older than all other caseasaurs, forcing the establishment of a long unrecorded lineage for caseids.
