Abstract

Abstract: Detailed correlation, based on conodont sequences, between middle and upper Lochkovian carbonate successions from two key peri‐Gondwanan regions, the Spanish Central Pyrenees and the Prague Synform, is attained for the first time. This correlation facilitates the definition of tie points for further multidisciplinary studies that seek to establish high‐resolution temporal subdivision and global correlation. Some intervals have a precision of less than 0.5 Ma, which is significantly greater than in previous studies. The estimated elapsed time considered herein is about 3.2 Ma and is subdivided into five major zones of global scope: transitans‐trigonicus, trigonicus‐kutscheri, kutscheri‐pandora β, pandora β‐ gilberti and gilberti‐steinachensis β. By providing tie points and globally applicable criteria, this research contributes to the international cooperative effort to subdivide the Devonian standard stages into globally recognised substages.
