Abstract

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.

3. References ( 1 ) and ( 2 ) report ages of 251.4 ± 0.3 Ma and ∼253 Ma respectively for P-Tr boundary ash beds from the same locality. Because the only published age for the Early-Middle Triassic boundary was determined in the same laboratory as in ( 1 ) we have chosen for consistency's sake to use the result from ( 1 ). The conclusions of this paper do not depend on which date is more accurate.
