Disused Palaeozoic regional stages from Belgium : Devillian, Revinian, Salmian, Gedinnian and Burnotian

The current status of some Palaeozoic stratigraphic units named in Belgium and the North of France (French Ardennes), and used until recently, is examined. Following the decisions of the International Commission on Stratigraphy (ICS), notably Gradstein et al (2004)’s paper, the terms Devillian, Revinian, Salmian, Gedinnian and Burnotian should be avoided as chronostratigraphic units. the names Revin, Deville, Salm and Burnot could however be used to characterise lithostratigraphic units of Belgium and adjacent areas.
