ABSTRACT We describe newly recovered cranial material of Bunostegos akokanensis, a pareiasaurian reptile known from the Upper Permian Moradi Formation of northern Niger. Bunostegos is highly autapomorphic, with diagnostic cranial features including two or three hemispherical bosses located above and between the external nares; laterally projecting supraorbital ‘horn’ formed by an enlarged postfrontal; large foramen present on ventral surface of postfrontal; and hemispherical supratemporal boss… 

The Vertebrate Fauna of the Upper Permian of Niger—IX. The Appendicular Skeleton of Bunostegos akokanensis (Parareptilia: Pareiasauria)

Interestingly, several aspects of its postcranial anatomy suggest that Bunostegos possessed relatively upright forelimb posture, which would be unique among pareiasaurs and possibly Permian amniotes as a whole.

The tetrapod fauna of the upper Permian Naobaogou Formation of China: a new species of Elginia (Parareptilia, Pareiasauria)

A new pareiasaur specimen is reported from the upper Permian Naobaogou Formation of the Daqing Mountains, Nei Mongol, China, recognized as a new species of Elginia, a taxon otherwise known only from theupper Permians Cutties Hillock Sandstone of Scotland.

The Vertebrate Fauna of the Upper Permian of Niger—XI. Cranial Material of a Juvenile Moradisaurus grandis (Reptilia: Captorhinidae)

Two partial skulls of juvenile individuals of Moradisaurus grandis, a moradisaurine captorhinid from the upper Permian Moradi Formation of northern Niger are described, and it is inferred that this skull is not skeletally mature and that the braincase would have fully ossified in larger, ontogenetically older individuals of this morad isaurine.

Cranial morphology and phylogenetic relationships of the Middle Permian pareiasaur Embrithosaurus schwarzi from the Karoo Basin of South Africa

The updated phylogenetic analysis recovers the four Middle Permian South African taxa as a monophyletic group for the first time, which is called Bradysauria, comprising a clade including Embrithosaurus,Bradysaurus baini and a polytomy including Nochelesaurus and Bradysaurus seeleyi.

Cranial morphology of the middle Permian pareiasaur Nochelesaurus alexanderi from the Karoo Basin of South Africa

ABSTRACT Pareiasaurs were globally distributed, abundant, herbivorous parareptiles with the basal-most members found only in the mid-Permian of South Africa. These basal forms form a monophyletic

A geometric morphometric analysis of the skull roof of Deltavjatia reveals an allometric increase in snout length and postorbital area, a result that can serve as a basis for examining morphological trends within pareiasaurs.

A New Eutherocephalian (Therapsida, Therocephalia) from the Upper Permian Madumabisa Mudstone Formation (Luangwa Basin) of Zambia

The new therocephalian therapsid Ichibengops munyamadziensis adds to a list of sister-group pairs of Wuchiapingian tetrapods in southern Gondwana and Laurasia, indicating that effective, though largely unknown, dispersal routes persisted in Pangea at least through early late Permian times.

Cranial morphology of embrithosaurus schwarzi (Parareptilia, Pareiasauria) and a taxonomic and stratigraphic reassessment of the South African Middle Permian Pareiasaurs

Pareiasaurs were abundant, large, herbivorous parareptiles of the middle and late Permian which had a global distribution. The most basal pareiasaurs are found only in the middle Permian of South

The vertebrate fauna of the Upper Permian of Niger—X. The mandible of the captorhinid reptile Moradisaurus grandis

ABSTRACT Recent field work in the upper Permian Moradi Formation of Niger has yielded new material of the late-occurring and largest moradisaurine captorhinid, Moradisaurus grandis. The material

THE VERTEBRATE FAUNA OF THE UPPER PERMIAN OF NIGER. IV. NIGERPETON RICQLESI (TEMNOSPONDYLI: COCHLEOSAURIDAE), AND THE EDOPOID COLONIZATION OF GONDWANA

The discovery of Nigerpeton strengthens support for the hypothesis that West Africa hosted an endemic fauna at the close of the Paleozoic Era and proposes that Late Carboniferous and Permian edopoids were geographically widespread and that they twice crossed the Central Pangean mountain chain (between Laurussia and Gondwana) during their evolution.

THE VERTEBRATE FAUNA OF THE UPPER PERMIAN OF NIGER. V. THE PRIMITIVE TEMNOSPONDYL SAHARASTEGA MORADIENSIS

A phylogenetic analysis of select Paleozoic temnospondyls indicates that S. moradiensis represents a late-surviving member of a clade that is the sister group of the Edopoidea, which suggests members of this clade may have been restricted to equatorial northwest Africa during the Late Carboniferous and Early Permian.

THE VERTEBRATE FAUNA OF THE UPPER PERMIAN OF NIGER—III, MORPHOLOGY AND ONTOGENY OF THE HINDLIMB OF MORADISAURUS GRANDIS (REPTILIA, CAPTORHINIDAE)

Hindlimb elements of the large captorhinid Moradisaurus grandis (Reptilia: Captorhinidae) recently collected from the Upper Permian Moradi Formation of north-central Niger are described and a well-preserved, articulated, and essentially complete juvenile pes indicates that the captorlinid centrale arose from the fusion of at least three ossification centers.

Anatomy and Phylogenetic Relationships of Sclerosaurus armatus (Amniota: Parareptilia) from the Buntsandstein (Triassic) of Europe

Certain apomorphic character states, particularly the presence of three spines on the quadratojugal, support Sclerosaurus referral to the Leptopleuroninae and places it in the Procolophonidae rather than as the sister taxon of Pareiasauria.

Anatomy of Emeroleter levis and the Phylogeny of the Nycteroleter Parareptiles

A clade consisting of the nycteroleters and pareiasaurs, here termed Pareiasauromorpha, is supported by both methods and is found to be paraphyletic with Bayesian inference.

The genus Pareiasaurus was instituted by Sir Richard Owen in 1876 for a large number of Reptilian remains from the Karroo Series of strata of South Africa, and regarded as represented by two species, which were named P. serridens and P. bombidens.

Les pareiasaures (Amniota, Parareptilia) du Permien supérieur du Bassin d'Argana, Maroc

The stapes, hitherto unknown in pareiasaurs, is described herein for the first time and displays a remarkably derived morphology, quite similar to that of the stapes of modern sauropsids.

Pareiasaur phylogeny and the origin of turtles

Many features thought to be restricted to turtles (and thus to have evolved simultaneously with the turtle shell) actually arose earlier, at various points along the pareiasaurian stem lineage.

Historical Burden In Systematics And The Interrelationships Of ‘Parareptiles’

Turtles are the highly modified survivors of a radiation of poorly‐known reptiles commonly called ‘parareptiles’, and the procolophonoid hypotheses is supported by only one synapomorphy (the slender stapes).
