Résumé :	Geological controversies about the Cambrian-Ordovician of the Montagne Noire (France) at the beginning of the 20th century: Jean Miquel's (1859-1940) contributions. Jean Miquel is one of the most important amateur naturalists who contributed, across the transition of the 19 and 20 centuries, to the improvement of the first Cambro-Ordovician stratigraphical charts on the southern Montagne Noire (Languedoc). A detailed knowledge of the regional geology on the area surrounding the locality where he was born (Barroubio) permitted him to subdivide properly these outcrops according to lithological and pale-ontological features, mainly the Lower-Middle Cambrian and the Arenigian (Lower Ordovician). He defined five Cambrian trilobite species and one echinoderm species. This paper offers a panorama of the evolution of historic concepts developed in the paleontology and stratigraphy of the Languedocian Lower Paleozoic during Miquel's life. This allows a better understanding of the influence in Languedoc of the first paleontological findings that took place in other regions, such as Wales, North America, Bohemia and the Armorican Massif.
