Givetian and early Frasnian conodonts from the Compte Section (Middle-Upper Devonian, Spanish Central Pyrenees)

, 2008
The Givetian and Frasnian conodont succession investigated in the Compte section (Spanish Pyrenees) is subdivided into nine Givetian standard conodont zones and two Frasnian zones (MN zones). This succession allows precise identification of the lower/middle Givetian, middle/upper Givetian and of the Givetian-Frasnian boundaries by means of index ...

Middle-upper Lochkovian (Lower Devonian) conodont succession in the section Segre 4 (Spanish central Pyrenees)

Abstract This study presents a detailed conodont-based biostratigraphic analysis of the Segre 4 section (Pyrenees), spanning the middle to upper Lochkovian. The section yields a continuous and well-preserved conodont succession comprising four globally recognized zones: the trigonicus–kutscheri
