Abstract
Occurrences of Neogene rocky shores in Portugal have been identified by help of bioerosion trace fossils. Ichnogenera Gastrochaenolites, Entobia, Caulostrepsis, Maeandropolydora and Trypanites are generally present. The importance of bioeroded surfaces for field recognition of wave-cut platforms, hard substrate marine-flooding surfaces (transgressive surfaces), and of major interruptions (hiatuses) in the stratigraphic record is stressed.
期刊介绍:
The Bulletin publishes contributions of international interest in all fields of geological sciences on results of new work on material from Denmark, the Faroes and Greenland. Contributions based on other material may also be submitted to the Bulletin if the subject is of relevance for the geology of the area of primary interest.
