The genera of primitive and synapsid reptiles which form the usual morphotypic series leading to cynodonts are not members of a phyletic series. Ecological analyses show three developing evolutionary lines during the Permo-Carboniferous—one lowland, living on deltas and in swamps; a second somewhat more upland; and a third distinctly upland. The members of these three lines are the source of the morphotypic genera, but most of them come from deposits formed in lowlands where they came by…

DIMETRODON (EUPELYCOSAURIA: SPHENACODONTIDAE) FROM THE LOWER PERMIAN ABO FORMATION, SOCORRO AND TORRANCE COUNTIES, NEW MEXICO

Abstract— We add to the sparse record of Dimetrodon from New Mexico by documenting three specimenscollected from two known Lower Permian Abo Formation vertebrate fossil localities that had not

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

A phylogenetic analysis of the tropidurine lizards (Squamata: Tropiduridae), including new characters of squamation and epidermal microstructure

The morphology of the inner surface zone of scales is described for the first time using scanning electron microscopy in a phylogenetic analysis of the Tropidurini and new characters and frequency coding of polymorphic characters help resolve the problematic relationships of several species.

A new species of Dimetrodon (Synapsida: Sphenacodontidae) from the Lower Permian of Germany records first occurrence of genus outside of North America

This first record of the sphenacodontid synapsid Dimetrodon outside of North America provides not only additional biological evidence of a continuous Euramerican landmass during the Early Permian, but also the absence of any major physical or biological barrier to faunal interchange of terrestrial vertebrates.

Lower Permian Terrestrial Paleoenvironments and Vertebrate Paleoecology of the Tambach Basin (Thuringia, Central Germany): The Upland Holy Grail

Abstract The Bromacker section of the Lower Permian, Tambach Formation, in central Germany, yields an important fossil-vertebrate assemblage that was deposited in an upland setting near the center of

REDESCRIPTION OF SEYMOURIA SANJUANENSIS (SEYMOURIAMORPHA) FROM THE LOWER PERMIAN OF GERMANY BASED ON COMPLETE, MATURE SPECIMENS WITH A DISCUSSION OF PALEOECOLOGY OF THE BROMACKER LOCALITY ASSEMBLAGE

Abstract Two nearly complete, articulated, mature specimens of the amphibian Seymouria are described from the Lower Permian Tambach Formation, lowermost unit of the Upper Rotliegend, of the Bromacker

First record of Seymouria (Vertebrata: Seymouriamorpha) from Early Permian fissure fills at Richards Spur, Oklahoma

Isolated skeletal elements of the amphibian genus Seymouria were recently discovered at the Richards Spur locality near Fort Sill, Oklahoma, a prolific source of Early Permian tetrapod remains. Five

LARGE DISSOROPHOID SKELETAL ELEMENTS FROM THE LOWER PERMIAN RICHARDS SPUR FISSURES, OKLAHOMA, AND THEIR PALEOECOLOGICAL IMPLICATIONS

Abstract Skeletal remains attributable to large dissorophoid amphibians, including four femora, two humeri, and an isolated palatine bone, have recently been recovered from the Lower Permian fissure

Anatomy and relationships of Haptodus garnettensis, a Pennsylvanian synapsid from Kansas

ABSTRACT New, well-preserved specimens of the Upper Pennsylvanian synapsid Haptodus garnettensis from Garnett, Kansas, represent more mature individuals than those available previously and indicate

Community Evolution and the Origin of Mammals

After a long period with relatively little adaptive radiation, these remnants provided the basis for the radiations of mammals that led to the great successes of the Cenozoic era.

PROBLEMS OF THE ORIGIN OF REPTILES

The earliest captorhino‐morphs, from the Lower Pennsylvanian, are already fully developed reptiles, and the limnoscelids and solenodonsaurids are more primitive forms, retaining features typical of anthracosaurian amphibians.

THE EVOLUTION OF A PERMIAN VERTEBRATE CHRONOFAUNA

The term chronofauna 1 is proposed to differentiate faunal units in which time is an important factor from those in which it is not, and to gain information concerning both physical and biological aspects of environment adequate to provide a background for study of many phases of adaptive modifications of animals.

This paper concerns alterations in the mechanical operation of the jaw from primitive reptiles to early mammals and defines the possible selection pressures responsible for the development and evolution of the synapsid coronoid process.
