INTRODUCTION. - The Montagne Noire has been celebrated for a century as showing
some of the finest Devonian sequences in Europe [1].  Already it has provided the recommended
Global Stratotype Section and Point (GSSP) for the Middle-Upper Devonian and Devonian-Carboniferous
boundaries.  The sections are also important for the definition of the Frasnian-Famennian boundary.  
From the Coumiac Quarry near Cessenon, de Rouville [2] illustrated the Frasnian Beloceras sagittarium.  
Ceratitic beloceratids have been described [3] and there is an account of the goniatite sequence [4].  
Conodont work established the importance of the sections [5] and it has formed the basis for a new approach
to Frasnian zonation [6].  There has been much debate on alleged mass extinctions at the Frasnian-Famennian
boundary but little recent precise documentation of evidence.  This Note records the current documentation
at Coumiac bearing on extinctions near the Frasnian-Famennian boundary mainly for colnodonts, goniatites
and trilobites.  The quarries at Coumiac lie some 1.5 km north of Cessenon (l/25,000 sheet, St Chinian,
Nos. 7-8). and form the type section of.the Coumiac Formation (53 m) which crosses the Frasnian-Famennian
boundary [7].  The locality and succession is illustrated here ( Figs. 1-3).
