Fig. 5From: A Unitary Association-based conodont biozonation of the Smithian–Spathian boundary (Early Triassic) and associated biotic crisis from South ChinaShanggang. Detailed stratigraphic log of the studied interval of the Shanggang section showing the distribution of conodont taxa and the δ13Ccarb record throughout the Smithian and Spathian part of the Luolou Formation. The LMHs and UAZ are indicated. Note the gap because of low angle faulting in the upper part of the black shalesBack to article page
