Abstract In their comment, Zhang et al. (2018) question the existence of the deformation structures that we report for the upper part of the Chahe Permian-Triassic Boundary reference section. These authors further suggest that this deformation contradicts the regional litho, bio- and chemostratigraphic results. Here again, and based on the outcrop picture provided by Zhang et al. (2018), we present new arguments attesting for a major tectonic deformation in the upper part of the Chahe section. W...

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 to study the terrestrial Permian–Triassic boundary, its correlation with the stratigraphically equivalent marine deposits, and to discuss the contemporaneity between the marine and terrestrial extinctions. The Chahe and Zhejue sections, which have already been studied in detail, especially using δ13C...

Abstract Volcanism was intense in western European basins during the Late Carboniferous–Early Permian transition, related to the late Variscan extension and associated magmatism. In the Autun Basin, explosive eruptions, expressed as highly weathered distal ashfall deposits (tonsteins), were preserved in lacustrine to swamp environments. The analysis of eleven tonsteins, confirmed as non-reworked volcanic horizons, indicates a highly explosive acidic calc-alkaline volcanism, with active volcanic ...

Abstract A novel well-preserved woody branch, Turpanopitys taoshuyuanense gen. et sp. nov. was collected in the early Triassic terrestrial deposits in the Turpan Basin, Northwest China. The permineralized wood is characterized by a heterogeneous pith, endarch primary xylem and Protophyllocladoxylon -type secondary xylem. The pith consists of parenchyma cells and supporting diaphragms formed by brick-like sclerenchyma cells. The quantitative growth-ring analyses of T. taoshuyuanense indicate that...

Abstract A novel well-preserved woody stem Junggaropitys dalongkouensis gen. et sp. nov. was collected from the Middle–Late Triassic sediments of the Karamay Formation in the Junggar Basin, Xinjiang Uygur Autonomous Region, Northwest China. The permineralized wood is characterized by a small homogeneous pith, endarch primary xylem and Protophyllocladoxylon -type secondary xylem. The quantitative growth-ring analyses of Junggaropitys dalongkouensis indicate that the species is evergreen, and the ...

Abstract This paper reviews critically the Permian–Triassic (P–Tr) fossil plants and microflora recorded in three well-studied terrestrial Permian–Triassic boundary (PTB) sections, namely Chahe, Zhejue, and Jiucaichong, and two marine–terrestrial transitional PTB sections, namely Mide and Tucheng, in western Guizhou Province and eastern Yunnan Province (WGEY), Southwest China. Distinct floral composition, abundance and diversity across the PTB allow the establishment of two terrestrial macroflor...

This work presents results of a compilation of all published palynological data as well as other unpublished data, on the basis of which a unified palynological biozonation is proposed for the Buntsandstein and Muschelkalk facies from the Iberian Ranges (Spain).

The aim of this study is to directly radiocarbon date pottery from prehistoric rock-art shelters in the Tassili n’Ajjer (central Sahara). We used a combined geochemical and microscopic approach to determine plant material in the pottery prior to direct 14C dating. The ages obtained range from 5270 ± 35 BP (6276–5948 cal BP) to 8160 ± 45 BP (9190–9015 cal BP), and correlate with the chronology derived from pottery typology. Our results document the transition from pre-Pastoral to Pastoral context...
