Bioerosion of Bermuda reefs

Palaeogeography, Palaeoclimatology, Palaeoecology, 1978
Abstract In order to test the usefulness of borings as indicators of palaeoenvironment a number of transects were sampled over a variety of reefs in Bermuda and an analysis was made of the borings and their inhabitants. The borings are described of 25 endolithic species, including sponges, a sea anemone, sipunculids, annelids, bivalves, a gastropod ...

Bioerosion and biogeomorphology

1992
Abstract Bioerosion is a complex set of physical and chemical processes of rock removal, driven by the interrelationships between (1) ‘biological corrosion’, a solutional process (accounting for 10-30 per cent of total erosion) largely engineered by Cyanobacteria, and (2) ‘biological abrasion’, the removal of these micro-organisms and ...

A stratigraphy of marine bioerosion

Geological Society, London, Special Publications, 2004
Abstract 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 stratigraphic studies of the trace-makers are not possible because (1) the rank of taxonomic ascription is too high to be meaningful and (2) not all ...

Bioerosive processes in Antarctic seas

Polar Biology, 2001
To date, marine boring organisms are not known for the whole Antarctic region, probably because of the scarcity of calcareous substrata. In Terra Nova Bay (Ross Sea), the study of some populations of the scallop Adamussium colbecki allowed us to record a bioerosive activity on carbonates due to a chlorophyte, belonging to the genus Phaeophyla. The same

Comment on 'Bioerosion, preparation and curation'

Geological Curator, 2005
We welcome the recent note by Radley and Twitchett (2004) for bringing one of the more unloved groups of fossils sensu lato into the curatorial limelight. Invertebrate trace fossils in any form, but particularly shallow-tier bioerosion structures, may cause curatorial headaches, and we consider discussion of these problems important in placing them on ...

Bioerosion of shells by terrestrial gastropods

Lethaia, 1999
Empty shells of terrestrial gastropods remain intact and become fossilized only under particular conditions. The usually thin shells are readily dissolved by rainwater, a process starting often during life. Results indicate that with this chemical weathering they may lose some 1% in weight per month.

Calcification, Silicification, Bioerosion

1984
Members of the phylum Porifera constitute an amazing array of species in terms of the kinds and shapes of mineral products they secrete. Depending upon the group, relatively enormous amounts of aragonite, calcite, and silica are secreted by these animals.

An online bibliography of bioerosion references

2008
A bibliography of bioerosion-related books and papers has been available on the Internet for several years. The list now includes almost 2200 references. This bibliography is freely available to the public and frequently edited, so it grows in size, coverage, and accuracy.
