Pridoli-middle Givetian
conodonts - Opis:
- Conodont faunas are generally sparse in Pridolito middle Givetian deposits from the Rabat-Tiflet area in the north western Moroccan Meseta. The Pridoli and Lochkovian rocks consist of dark platy limestones alternating with dark shales containing graptolites in some levels. In the over lying part of the succession carbonate rocks predominate with the development of reefoid limestones in the lower Givetian. The eosteinhornensis, sulcatus, dehiscens vel kitabicus, laticostatus/inversus, partitus, ensensis, hemiansatus, timorensis and rhenanus/varcus zones have been recognized by occurrence of the conodont in dexspecies.The first appearance of Belodella devonica, occurring together with the graptolite Monograptus uniformis is used as a regional index species for the base of the Devonian. The age of some levels in the succession were previously dated by graptolites, dacryoconarids and rare goniatites.
