Taphonomic Effects and Preserved Overgrowth Relationships among Encrusting Marine Organisms

摘要: Overgrowth relationships in the fossil record of encrusting organisms on marine hard substrata have been used to infer success competitive interactions, particularly for modular such as colonial invertebrates and coralline algae. However, this interpretation has questioned varying extenteven by those who procedure-because possibility that any individual observation may represent growth over a senescent organism or dead skeletal remains. Where sufficient numbers overgrowth are available demonstrate proportions overgrowths between two taxa not essentially equal, superiority more frequently overgrowing taxon should be accepted. The degree was at least great seen probably substantially greater, depending upon percent bare surface substratum. RESEARCH LETTERS 279
