Fig. 3. Organic δ¹³C, total organic carbon, Hg loading and Hg/TOC, and total teratology for Stenlille-1 and Rødby-1.

(A) Stenlille-1, and (B) Rødby-1. The LTT- and LCT-spore teratology is expressed as percentage of the total number of specimens counted within each genus per sample, as well as total severity of sample expressed as colors. Lithology and intervals used to subdivide the TJB succession mainly after reference (32). Stars denote approximate position of terrestrial coal/coaly beds in the Danish Basin (45). Number of stars indicates frequency of wildfires. Larger star size indicates higher estimated burning temperature (45). Red arrows on (A) mark levels where Hg and Hg/TOC decrease, while TOC levels remain high. Note that TOC values below the detection levels are marked with white squares and that no Hg/TOC values were calculated for these samples. VPDB, Vienna Pee Dee belemnite.
