D: Microstratigraphy of Jo's Quarry site. E: Microstratigraphy of Beecher's Bed site. Inset columns highlight beds with pyritized soft tissues (scale is on left in centimeters; grain size at base: c—clay, s—silt, fs—fine-grained sand). Note similarities in thickness, grain size, and surrounding sediment as well as frequent association with carbonate concretions. F: Highly reactive iron/total iron, FeHR/FeT; pyrite iron, FeP/FeHR, FeT/Al, and δ34S profiles through section from Beecher's Bed (corresponding to the lower part of E). Note consistency of all signatures in each of the trilobite beds, although heavy sulfur isotopic signal (suggesting a rapidly closed system) is most diagnostic.
