Experimental etching with hydrofluoric acid indicated that silica deposition occurs in a recognizable pattern in common sponge microscleres. The postdepositional alteration of these spicules has previously been generally unrecognized or misinterpreted in the literature. Early stages of postdepositional etching of sponge spicules were observed in the acid insoluble fraction of sediments from the West Atlantic barrier reef near Carrie Bow Cay, Belize. Preliminary data on silica distribution in… 

Spatial distribution of sponge spicules in sediments around Taiwan and the Sunda Shelf

Biogenic silica (BSi) in marine sediments is an important indicator of siliceous organism distributions and paleoproductivities. Organisms that have BSi skeletons include diatoms, silicoflagellates,

LAGOON SPONGES FROM CARRIE BOW CAY (BELIZE): ECOLOGICAL BENEFITS OF SELECTIVE SEDIMENT INCORPORATION

TLDR
The anchoring ability for thirteen common species in the lagoon of Carrie Bow Cay (Belize) is determined by evaluating the type and amount of incorporated sediments and comparing them with the nearby substrate components.

Preservation of siliceous sponges in the Jurassic of southern England and northern France

Reef-forming lithistid sponges in the Middle Jurassic (Bathonian) of Normandy, France, were lithified on the sea floor by a peloidal cement, probably of an original low-Mg calcite composition

The method of spicular analysis that examines surficial sediments has been used to study the sponge spicule assemblage in the lagoon reef of Bocas del Toro, Panama. The method allowed to recognize

Contribution of Sponge Spicules to the Composition of Biogenic Silica in the Ligurian Sea

TLDR
The concentration of spicules in the trapped sediments underlines an unexpect- ed trend, with low values in spring and summer, and increasing in autumn and winter, probably linked to the biological cycles of the demosponges.

DO SPICULES IN SEDIMENTS REFLECT THE LIVING SPONGE COMMUNITY? A TEST IN A CARIBBEAN SHALLOW-WATER LAGOON

TLDR
Spicular analysis is a tenable tool in the reconstruction of former sponge communities, but not of the share of various sponge species, and may also help reveal the presence of cryptic and excavating species that are often overlooked in traditional studies.

Early ordovician microbial-sponge-receptaculitid bioherms of the precordillera, western Argentina

SummaryReef-mounds built by benthonic microbes, lithistid sponges, and the receptacultidCalathium occur near the base of the Early Ordovician San Juan Formation of the western Argentine

Sponge Contributions to the Geology and Biology of Reefs: Past, Present, and Future

Histories of sponges and reefs have been intertwined from the beginning. Paleozoic and Mesozoic sponges generated solid building blocks, and constructed reefs in collaboration with microbes and other

Upper Silurian lithistid sponge reefs on Somerset Island, Arctic Canada

The Upper Ludlow Douro Formation contains the first reported Silurian sponge reefs. These relatively small (5–35 m diameter), mound-shaped structures contain, on average, 35% lithistid demosponges.

ABSTRACT Opaline sponge spicules are being preferentially removed from reef as opposed to back-reef sediments from North Jamaica. In contrast to presumed chemical solution of silica in the deep sea,

Mechanism of Internal Stratification of Siliceous Sponge Spicules

TLDR
Internal fine structure in spicule fossils would provide a valuable comparison with present day spicules and may offer clues as to climatological or ecological conditions in that period.

Sponges in coral reefs

Sponges are sessile aquatic metazoans, bounded by pinacoderm and containing choanocyte chambers. Choanocytes generate a waterflow from small ostia, through an incurrent and excurrenl aquiferous
