Herbert J. Sullivan A well-preserved spore flora containing elements diagnostic of a Tournaisian age has been obtained from a horizon approximately 100 ft. above the base of the Cementstone Group in Ayrshire. A total of twenty-two species of spores have been recognized in the assemblage; of these, eight are new. Comparison with assemblages from other parts of the world has indicated regional variations in the composition of the Tournaisian spore floras. The Palaeontological Association (Free Access)
