Abstract
Synopsis: A recent collection of fossil fishes from concretions in the Lower Oil Shale Group (Lower Carboniferous) of the Wardie Shore north of Edinburgh has enabled the fish-bearing strata, originally described as 70 ft of black shale, to be subdivided on characteristics of the concretions. Other horizons above and below these strata also yielded specimens. The numbers of various genera collected from these beds have been expressed as a table, which may form the basis for future studies on palaeoecology. The abundance of well preserved elasmobranchs is the most important result of this work, and may make necessary a reconsideration of the environment.
