Book Description
This study contains a documentation of conodont biofacies deduced from fragments of the shelf margin facies to establish a biostratigraphic zonation and to determine conodont paleoecology of the inner marginal environment through the Arenig interval. Among clasts in the megaconglomerates, local (lower slope derived), foreign (shelf, shelf break, and upper slope derived), and older clasts were distinguished. About 300 conodont samples were collected and processed, mainly from clasts of the three conglomerate horizons. The 12,492 conodont specimens recovered represent 132 different form and multi-element species.
