High-precision timeline for Earth’s most severe extinction

Abstract: Significance Mass extinctions are major drivers of macroevolutionary change and mark fundamental transitions in the history of life, yet the feedbacks between environmental perturbation and biological response, which occur on submillennial timescales, are poorly understood. We present a high-precision age model for the end-Permian mass extinction, which was the most severe loss of marine and terrestrial biota in the last 542 My, that allows exploration of the sequence of events at millennial to decam… Show more

“…As a consequence, the zonation established here confirms the empirical scheme previously established by The duration of each UA-zone can be estimated using the latest high-precision single zircon U-Pb ages obtained from South China. An age of 251.88 ± 0.031 Ma for the Permian-Triassic boundary has been recently proposed by Burgess et al (2014). An age of 251.22 ± 0.2 Ma for the early Smithian Kashmirites kapila beds (corresponding here to SM-5 according to Brühwiler et al, 2010b) is provided by Galfetti et al (2007b).…”

“…Zircon was separated at the Massachusetts Institute of Technology (MIT) using conventional heavy liquid techniques. Uranium and Pb isotopic data were obtained using a VG Sector 54 and IsotopX X-62 mass spectrometers at MIT using analytical procedures from Burgess et al (2013). Whole rock Nd, Sr and Pb isotopic data from these samples were obtained at the University of Colorado, Boulder using analytical procedures outlined by Farmer et al (1991).…”

“…The excellent preservation of the associated vertebrate assemblages has led to a large library of published faunal information, complemented by palynological data, that has been extrapolated globally to understand the patterns of tetrapod extinctions and their timing relative to the end-Permian marine extinction at ca. 252 Ma (Burgess et al, 2014;Lucas, 2010;Mundil et al, 2004;Shen et al, 2011;Ward et al, 2005).…”

“…The Permian-Triassic boundary (PTB) is defined by marine conodont assemblages, and has a corresponding age of 251.9 ± 0.0 Ma determined from high resolution U-Pb TIMS (zircon) dating of ash beds from the Meishan section in south China (Burgess et al, 2014).…”
