Abstract

Study of the La Guardia d'Àres section from the Spanish Central Pyrenees has yielded significant conodont faunas relevant for the subdivision of the Emsian stage. Four Polygnathus species are described and discussed: P. laticostatus, P. gilberti, P. linguiformis bultyncki and P. vigierei. The latter three are cited for the first time from the Spanish Central Pyrenees. The new conodont record includes two of the three conodont index taxa proposed for the identification of the lower Emsian/upper Emsian boundary (P. laticostatus and P. gilberti). Consequently, they may prove useful for the future decision on the position of this boundary by the Subcommission on Devonian Stratigraphy. These data allow a precise placement of the boundary in the Spanish Central Pyrenees.
