A new fossil amniote from the Fossil Forest of Chemnitz (Sakmarian-Artinskian transition, Germany) is described as Ascendonanus nestleri gen. et sp. nov., based on five articulated skeletons with integumentary preservation. The slender animals exhibit a generalistic, lizard-like morphology. However, their synapsid temporal fenestration, ventrally ridged centra and enlarged iliac blades indicate a pelycosaur-grade affiliation. Using a renewed data set for certain early amniotes with a similar… Expand

A new varanopid synapsid from the early Permian of Oklahoma and the evolutionary stasis in this clade
TLDR
A new varanopid taxon is reported, represented by substantially more complete material, which supports the placement of this taxon within Mesenosaurus, as a new species, Me. efremovi. Expand
Varanopid from the Carboniferous of Nova Scotia reveals evidence of parental care in amniotes
TLDR
A fossil synapsid from the Carboniferous period of Nova Scotia that displays evidence of parental care is reported that adds to growing evidence that parental care was more widespread among Palaeozoic synapsids than previously thought and provides data permitting the identification of potential ontogeny-dependent traits within varanopids. Expand
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. Expand
Re-evaluation of an early sphenacodontian synapsid from the Lower Permian of England

  • Biology
  • Earth and Environmental Science Transactions of the Royal Society of Edinburgh
  • 2020
TLDR
The holotypic isolated maxilla of the early sphenacodontian Haptodus grandis from the Cisuralian of England is revisited and reveals a mosaic distribution of maxillary features, most significantly regarding the precanine region. Expand
Medullosan seed ferns of seasonally-dry habitats: old and new perspectives on enigmatic elements of Late Pennsylvanian–early Permian intramontane basinal vegetation
Abstract The medullosans represent a diverse group of pteridosperms that was widely distributed in forested landscapes of the late Paleozoic. These plants became widely known from the extensive… Expand
A reexamination of Milosaurus mccordi, and the evolution of large body size in Carboniferous synapsids
ABSTRACT Milosaurus mccordi was described in 1970 as a large, pelycosaurian-grade synapsid from the latest Carboniferous of Illinois but has since received little attention. Here, the holotype and… Expand
A faunivorous early sphenacodontian synapsid with a diastema
Our knowledge on early sphenacodontian and edaphosaurid synapsids, the group that includes the origin of the mammalian lineage, largely arose from the Pennsylvanian Garnett locality in Kansas. A… Expand
A new mesenosaurine from the lower Permian of Germany and the postcrania of Mesenosaurus: implications for early amniote comparative osteology
TLDR
An investigation of limb proportions may suggest the occurrence of facultative bipedalism in Mesenosaurus and Cabarzia, and the documentation for both genera provides the most complete postcranial descriptions of non-varanodontine varanopids. Expand
Reassessment of historic ‘microsaurs’ from Joggins, Nova Scotia, reveals hidden diversity in the earliest amniote ecosystem
‘Microsaurs’ are traditionally considered to be lepospondyl non-amniotes, but recent analyses have recovered a subset of ‘microsaurs’, the fossorially adapted Recumbirostra, within Amniota. This… Expand
Cranial osteology and systematics of the enigmatic early ‘sail-backed’ synapsid Echinerpeton intermedium Reisz, 1972, and a review of the earliest ‘pelycosaurs’
TLDR
The first new remains of Echinerpeton since its initial discovery are described, and the phylogenetic position of the taxon is revisited using Bayesian inference and parsimony-based methods, confirming it as a member of Ophiacodontidae. Expand

Varanops brevirostris (Eupelycosauria: Varanopidae) from the Lower Permian of Texas, with Discussion of Varanopid Morphology and Interrelationships
ABSTRACT A comprehensive revision of Varanops brevirostris on the basis of a large, well-preserved specimen from a new Lower Permian locality in Texas provides valuable new anatomical information and… Expand
A Re-Description of ‘Mycterosaurus’ smithae, an Early Permian Eothyridid, and Its Impact on the Phylogeny of Pelycosaurian-Grade Synapsids
TLDR
An expanded version of a recently published phylogenetic analysis of pelycosaurian-grade synapsids positions Vaughnictis as the sister taxon of Eothyris within the clade Eothirididae, and confirms the recently-disputed position of caseasaurs as the most basal synapsid. Expand
The last “pelycosaur”: a varanopid synapsid from the Pristerognathus Assemblage Zone, Middle Permian of South Africa
We report on a partial varanopid skull and mandible from the Pristerognathus Assemblage Zone of the Beaufort Group, in the South African Karoo Basin, which is probably latest Middle Permian… Expand
Aerosaurus wellesi, new species, a varanopseid mammal-like reptile (Synapsida : Pelycosauria) from the Lower Permian of New Mexico
ABSTRACT Aerosaurus wellesi n. sp. is based upon two nearly complete articulated skeletons from the Lower Permian deposits near Arroyo del Agua, New Mexico. Study of these superbly preserved… Expand
First European Record of a Varanodontine (Synapsida: Varanopidae): Member of a Unique Early Permian Upland Paleoecosystem, Tambach Basin, Central Germany
A new genus and species of varanodontine varanopid, Tambacarnifex unguifalcatus, is described on the basis of the greater portion of the postcranium and a closely associated partial left dentary from… Expand
AN EARLY PERMIAN VARANODONTINE VARANOPID (SYNAPSIDA: EUPELYCOSAURIA) FROM THE RICHARDS SPUR LOCALITY, OKLAHOMA

Anatomy and Relationships of the Middle Permian Varanopid Heleosaurus scholtzi Based on a Social Aggregation from the Karoo Basin of South Africa
TLDR
Phylogenetic analysis of Varanopidae using an augmented data matrix from the literature positions Heleosaurus as the sister taxon of Elliotsmithia within the varanopid subfamily Mycterosaurinae, and both this sister-group relationship and the monophyly of MyCTerosaurinee are weak and collapse with one extra step.

PYOZIA MESENENSIS, A NEW, SMALL VARANOPID (SYNAPSIDA, EUPELYCOSAURIA) FROM RUSSIA: “PELYCOSAUR” DIVERSITY IN THE MIDDLE PERMIAN
TLDR
The discovery of the basal Pyozia suggests that varanopids maintained their diversity in the Middle Permian, and is placed as sister taxon to the terminal dichotomy of Mycterosaurinae and Varanodontinae. Expand
