The Permian–Triassic boundary crisis and Early Triassic biotic recovery
This issue of Palaeogeography Palaeoclimatology Palaeoecology is devoted to papers on the Permian– Triassic boundary crisis and Early Triassic biotic recovery. It is an outgrowth of the Symposium on Early Triassic Chronostratigraphy and Biotic Recovery that was held in Chaohu, China, on May 21st–23rd, 2005 under the auspices of IGCP Project 467 and attended by about 200 Earth scientists with a ...
متن کاملA reappraisal of the Middle Triassic chirotheriid Chirotherium ibericus Navás, 1906 (Iberian Range NE Spain), with comments on the Triassic tetrapod track biochronology of the Iberian Peninsula
Triassic vertebrate tracks are known from the beginning of the 19th century and have a worldwide distribution. Several Triassic track ichnoassemblages and ichnotaxa have a restricted stratigraphic range and are useful in biochronology and biostratigraphy. The record of Triassic tracks in the Iberian Peninsula has gone almost unnoticed although more than 25 localities have been described since 1...
متن کاملThe Permian–Triassic boundary in Antarctica
The Permian ended with the largest of known mass extinctions in the history of life. This signal event has been difficult to recognize in Antarctic non-marine rocks, because the boundary with the Triassic is defined by marine fossils at a stratotype section in China. Late Permian leaves (Glossopteris) and roots Vertebraria), and Early Triassic leaves (Dicroidium) and vertebrates (Lystrosaurus) ...
متن کاملSulfur geochemistry across a terrestrial Permian^Triassic boundary section in the Karoo Basin, South Africa
Concentrations of sulfur and carbon, and isotopic compositions of sulfur were determined in sedimentary rocks from a section across the terrestrial Permian^Triassic (P^Tr) boundary in the northern Karoo Basin, South Africa. High concentrations of sulfide produced by sulfate-reducing bacteria were found in the sedimentary rocks at and just below the perceived P^Tr boundary. The ratios of organic...
متن کاملFixed, free, and fixed: the fickle phylogeny of extant Crinoidea (Echinodermata) and their Permian-Triassic origin.
Although the status of Crinoidea (sea lilies and featherstars) as sister group to all other living echinoderms is well-established, relationships among crinoids, particularly extant forms, are debated. All living species are currently placed in Articulata, which is generally accepted as the only crinoid group to survive the Permian-Triassic extinction event. Recent classifications have recogniz...
