The Golfe d’Arguin offshore of northern Mauritania hosts a rare modern analogue for heterozoan carbonate production in a tropical marine setting. Dominated by ocean upwelling and with additional fertilisation by iron-rich aeolian dust, this naturally eutrophic marine environment lacks typical photozoan communities. A highly productive, tropical cosmopolitan biota dominated by molluscs and suspension-feeders such as bryozoans and balanids characterises the carbonate-rich surface sediments… Expand

Palaeoenvironmental dynamics of Holocene shoreface bryoliths from the southern coast of Brazil
Beds of free-living coated nodules (coralline algae, bryozoans, acervulinid foraminifera) create shallow-water carbonate biogenic benthic habitats, which are sensitive to human disturbance and slowExpand
Bryozoans on the move: adaptations to hard substrate-limiting tropical heterozoan carbonates (Banc d’Arguin, Mauritania)
The Banc d’Arguin off Mauritania hosts an extensive warmwater heterozoan carbonate factory that is unique in the present-day world. Tropical waters characterize this epicontinental gulf, which lacksExpand
Facies patterns of a tropical heterozoan carbonate platform under eutrophic conditions: the Banc d’Arguin, Mauritania
High-nutrient tropical carbonate systems are known to produce sediments that, in terms of skeletal composition, are reminiscent of their extra-tropical counterparts. Such carbonate systems andExpand

Palaeoenvironmental analysis of the Miocene barnacle facies: case studies from Europe and South America
Abstract Acorn barnacles are sessile crustaceans common in shallow-water settings, both in modern oceans and in the Miocene geological record. Barnacle-rich facies occur from polar to equatorialExpand
Redescription and palaeoecological significance of the bryozoan Hippoporidra patagonica (Pallaroni, 1920) in the San Julián Formation (late Oligocene) of Santa Cruz province, Argentina
Hippoporidra is a cheilostome bryozoan that predominantly encrusts gastropod shells inhabited by hermit crabs. The genus has a Pan-Atlantic distribution and its fossil record ranges from the EoceneExpand
Nutrient influence on fossil carbonate factories: Evidence from SEDEX extractions on Burdigalian limestones (Miocene, NW Italy and S France)
Abstract Different Miocene shallow-water carbonate successions have been examined to test the potential of phosphorus sequential extraction (SEDEX) in studying palaeo-nutrient levels, and toExpand
Competition between encrusters on marine hard substrates and its fossil record
TLDR
If carefully interpreted, the fossil record of sclerobionts can provide an as yet largely unexploited resource for studying the long-term ecological and evolutionary dynamics of competition. Expand
