Marine organisms have occupied hard substrates since the Archaean. Shells, rocks, wood
and sedimentary hardgrounds offer relatively stable habitats compared to unconsolidated …

Abstract The Ordovician Period records an extraordinary biodiversity increase known as the
Great Ordovician Biodiversification Event (GOBE), which coincided with a series of …

The new edition of this work includes an appendix listing criteria for the identification of
ichnotaxa. It covers all aspects of tiering trace fossil diversity and ichnoguilds, and is aimed …

The 'Great Ordovician Biodiversification Event'(GOBE) saw a spectacular increase in marine
biodiversity at all taxonomic levels largely within the phyla established much earlier during …

Sequence stratigraphy provides an integrated framework within which to examine historical
patterns of paleontological phenomena. Depositional sequences are the stratigraphic record …

Profound changes in the biodiversity and biocomplexity of marine life occurred during the
early to mid-Ordovician through an interval of some 25 Myr. The planet's seascapes were …

About 65 ichnogenera and a number of bioerosional trace fossils that are unnamed are
catalogued with respect to their stratigraphic ranges. In most cases, corresponding …

Paleoecology has a dual relationship with sequence stratigraphy. On one hand, body and
trace fossils, together with their taphonomy, may provide sensitive indicators of …

The trophic structure of modern tropical benthic communities, especially reefs, is profoundly
influenced by ambient nutrient levels and resultant predator characteristics. In oligotrophic …

Morphological similarities indicate that Palaeozoic problematic tubeworms, eg tentaculitids,
cornulitids, microconchids, trypanoporids, Anticalyptraea, and Tymbochoos, form a …
