dc.description.abstract1. Conodonts are rare in the Scottish Carboniferous Limestone but are slightly more abundant in the lower Dart of the Scottish Millstone Grit.en
dc.description.abstract2. Seventeen genera and 53 species (including one new genus, Dalryella, and 21 new species) of conodonts are recognised and described.en
dc.description.abstract3. Apart from Gnathodus carinatus, confined to the Lower Limestone Group, and G. smithi; indicative of the upper part of the Upper Limestone Group, conodonts have been found unsuitable for stratigraphic discrimination within the Carboniferous Limestone.en
dc.description.abstract4. Two genera, Idiogn.athodus and Streptognathodus, diagnostic of the Pennsylvanian of N. America first appear near the horizon of the well -known palaeontological break in the lower part of the Millstone Grit thereby strengthening the evidence for correlating this break with the American Mississippian /Pennsylvanian boundary.en
dc.description.abstract5. The range of Apatggnathus must be extended from the top of the Devonian to near the top of the Upper Limestone Group.en
