Abstract The most extensive Permian tetrapod (amphibian and reptile) fossil records from the western United States (New Mexico-Texas) and South Africa provide the basis for definition of 10 land-vertebrate faunachrons that encompass Permian time. These are (in ascending order): the Coyotean, Seymouran, Mitchellcreekian, Redtankian, Littlecrotonian, Kapteinskraalian, Gamkan, Hoedemakeran, Steilkransian and Platbergian. These faunachrons provide a biochronological framework with which to…

The Beaufort Group of the main Karoo Basin of South Africa records two major extinction events of terrestrial vertebrates in the late Palaeozoic. The oldest of these has been dated to the late

The Permian timescale: an introduction

Abstract The Permian timescale has developed over about two centuries of research to the current chronostratigraphic scale advocated by the Subcommission on Permian Stratigraphy of three series and

Abstract Permian tetrapod footprints are known from localities in North America, South America, Europe and Africa. These footprints comprise four ichnofacies, the Chelichnus ichnofacies from

Biostratigraphic significance and geometric morphometrics of Euestheria gutta (Crustacea: Branchiopoda: Spinicaudata): An index fossil of continental Permian–Triassic transitional beds

The Permian–Triassic mass extinction was the largest biotic extinction event in the Phanerozoic and affected both marine and continental life. Marine Permian–Triassic transitional sequences can be

Outline of a Permian tetrapod footprint ichnostratigraphy

Abstract Tetrapod footprints are among the most common fossil remains in continental Permian strata and thus are of biostratigraphic interest. Based on the vertical distribution of the 13 best-known

For about a half century, most vertebrate paleontologists have correlated the youngest Permian tetrapod assemblages in North America, which are from the San Angelo, Flowerpot and Chickasha formations

Has the utility of Dicynodon for Late Permian terrestrial biostratigraphy been overstated

Dicynodont therapsids have long played an important role in global Late Permian and Triassic biostratigraphy, including recent studies of the effects of the extinction at the Permian-Triassic

Permian tetrapods from the Sahara show climate-controlled endemism in Pangaea

The results show that long-standing theories of Late Permian faunal homogeneity are probably oversimplified as the result of uneven latitudinal sampling, and suggest that faunas from the poorly sampled xeric belt that straddled the Equator during thePermian period differed markedly from well-sampled fauna that dominated tropical-to-temperate zones to the north and south.


Summary The tetrapods from early Carboniferous to early Triassic times comprise the majority of fossil amphibia and the first great development of the reptiles. They are found associated with two

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

The San Angelo Formation, Permian of Texas, and Its Vertebrates

A vertebrate fauna has been obtained from the San Angelo formation, Permian, of Hardeman and Foard counties, Texas. This formation, which is composed of sandstones, red shales, and conglomerates, is

Ecosystem remodelling among vertebrates at the Permian–Triassic boundary in Russia

The nature of the event in Russia is document in a comprehensive survey of 675 specimens of amphibians and reptiles from 289 localities spanning 13 successive geological time zones in the South Urals basin, with a profound loss of genera and families and simplification of ecosystems.
