Abstract: Vertebrate paleontologists have proposed a model for the terrestrial end-Permian event in the Karoo Basin, South Africa. The scenario envisions vegetational collapse that resulted in a phased extinction of vertebrate taxa in the uppermost Daptocephalus Assemblage Zone and overlying Lystrosaurus Assemblage Zone. These biodiversity patterns are placed into composite stratigraphic sections at key localities, several of which are in close spatial proximity. We present a stratigraphic… Expand

Siltstones Across the Daptocephalus (Dicynodon) and Lystrosaurus Assemblage Zones, Karoo Basin, South Africa, Show No Evidence For Aridification
Abstract:  Changes in the record of vertebrate-assemblage zones in the Karoo Basin, South Africa, serve as a model for the response of terrestrial ecosystems to the end-Permian biotic crisis.… Expand
TESTING THE DAPTOCEPHALUS AND LYSTROSAURUS ASSEMBLAGE ZONES IN A LITHOSTRATOGRAPHIC, MAGNETOSTRATIGRAPHIC, AND PALYNOLOGICAL FRAMEWORK IN THE FREE STATE, SOUTH AFRICA
Abstract: The vertebrate-fossil record in the Karoo Basin has served as the accepted model for how terrestrial ecosystems responded to the end-Permian extinction event. A database of several hundred… Expand
Calcic Vertisols in the upper Daptocephalus Assemblage Zone, Balfour Formation, Karoo Basin, South Africa: Implications for Late Permian Climate
The fully continental succession of the Beaufort Group, Karoo Basin, South Africa, has been used in the development of environmental models proposed for the interval that spans the contact between… Expand
A multidisciplinary approach to review the vertical and lateral facies relationships of the purported vertebrate-defined terrestrial Permian–Triassic boundary interval at Bethulie, Karoo Basin, South Africa
Abstract The stratigraphic section at Bethulie, South Africa, is reported to contain the vertebrate-defined Permian–Triassic boundary succession in the terrestrial realm of the Karoo Basin. The model… Expand
Palaeoenvironmental changes recorded in the palynology and palynofacies of a Late Permian Marker Mudstone (Galilee Basin, Australia)
Reconstructing the terrestrial palaeoenvironment during the end-Permian is made challenging by widespread erosion and ecosystem destruction. High-resolution sampling for palynofacies and palynology… Expand
A new approach to biostratigraphy in the Karoo retroarc foreland system: Utilising restricted-range palynomorphs and their first appearance datums for correlation
Abstract The main Karoo Basin (MKB), internationally renowned for its wealth of fossil tetrapods, has been lithostratigraphically subdivided into three discrete regions: two (east and west) proximal… Expand
Terrestrial Permian–Triassic boundary in southern China: New stratigraphic, structural and palaeoenvironment considerations
The Permian–Triassic boundary is located above the main Phanerozoic terrestrial and marine biotic crisis. Southwest China (eastern Yunnan and western Guizhou) is considered as an ideal place in Asia… Expand
New geochemical and palaeontological data from the Permian-Triassic boundary in the South African Karoo Basin test the synchronicity of terrestrial and marine extinctions
Abstract The end-Permian mass extinction (EPME) is widely recognised as the largest mass extinction in Phanerozoic history. In marine strata the main extinction event is well constrained, and has… Expand
Late Permian conchostracans (Crustacea, Branchiopoda) from continental deposits in the Moscow Syneclise, Russia
Abstract. The Moscow Syneclise on the East European Platform is an important area for the study of the continental biota of late Permian to Early Triassic age in continuous sections. This study… Expand
The base of the Lystrosaurus Assemblage Zone, Karoo Basin, predates the end-Permian marine extinction
TLDR
High resolution dating of the Lystrosaurus Assemblage Zone in the Karoo Basin, South Africa, is presented, demonstrating that the marine crisis did not mirror a coeval event on land and refuting the previously used stratigraphic marker for terrestrial end-Permian extinction. Expand
