Between the highest worked seam in the middle Coal Measures and the upper Coal Measures in Fife, eastern Scotland, is a little known sequence of strata containing Skipsey's marine band, taken to mark the boundary between the middle and upper Coal Measures. A recently driven crosscut has revealed a section, given here, that contains two marine bands, thus necessitating revision of the local stratigraphy and correlation of fossils since the unrecorded marine band occurs 70 feet lower in the section. The meaning of local reddening of some of the beds seems to be related to a zone of partial oxidation beneath a major unconformity. These beds, however, are distinct from primary red beds in the upper Coal Measures that may be equivalent to the Etruria marl of the Midlands.
