Description:
High-resolution carbon isotope measurements of multiple stratigraphic sections in south China demonstrate that the pronounced carbon isotopic excursion at the Permian-Triassic boundary was not an isolated event but the first in a series of large fluctuations that continued throughout the Early Triassic before ending abruptly early in the Middle Triassic. The unusual behavior of the carbon cycle coincides with the delayed recovery from end-Permian extinction recorded by fossils, suggesting a direct relationship between Earth system function and biological rediversification in the aftermath of Earth's most devastating mass extinction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Payne, Jonathan L -- Lehrmann, Daniel J -- Wei, Jiayong -- Orchard, Michael J -- Schrag, Daniel P -- Knoll, Andrew H -- New York, N.Y. -- Science. 2004 Jul 23;305(5683):506-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth and Planetary Sciences, Harvard University, 20 Oxford Street, Cambridge, MA 02138, USA. jpayne@fas.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15273391" target="_blank"〉PubMed〈/a〉
