Summary: We have compiled the stratigraphic ranges of various taxa of carbonate producers in the Cretaceous period and summarized their ecological and physiological controls on calcification and carbonate production. The observed diversity patterns are compared with proxy data of Cretaceous climate and seawater chemistry to elucidate the effect of environmental change on carbonate production and sedimentation. Two characteristic patterns are recognized: the diversity of certain taxa trace the evolution of Cretaceous sea level, while the diversity of other taxa show significant reductions at the level of oceanic anoxic events (OAEs). Our findings highlight the vulnerability of benthic carbonate producers to environmental changes and the importance of high sea level and high temperatures in controlling diversity in certain taxa. Aragonitic or aragonite-dominated carbonate producers are most affected during extinction events related to OAEs, and there is a trend of decreasing aragonite dominance throughout the Cretaceous.

Summary: The presence of magnesium in natural waters can strongly inhibit calcite precipitation and the transformation of aragonite to calcite. The rate at which aragonite stabilizes to calcite increases with lower fluid:solid ratios. Increases in fluid:solid ratio also lead to greater incorporation of magnesium into calcite products, suggesting that fluid:solid ratio is an important factor in carbonate diagenesis.

Summary: The organic matrix ASM extracted from the shells of P. placenta plays a significant role in the formation of foliated calcite laths. It can stabilize the amorphous calcium carbonate precursor and inhibit the nucleation of calcium carbonate. ASM is incorporated into the preliminary nanocrystals and occluded into the calcite crystals, stabilizing other crystal planes instead of the thermodynamic {104} planes.

Summary: The Mg/Ca and δ18O paleothermometers give discrepant values in recrystallized tests, potentially due to diffusively limited closed-system recrystallization. The Mg/Ca ratio is more diagenetically robust and can be used as a more reliable paleotemperature proxy.

Summary: The study focuses on U-Pb dating of flowstones in South African caves, revealing patterns in age quality related to U and Pb concentrations. The dataset is divided into 'good', 'bad' and 'ugly' ages based on % error, with factors such as number of isochron points and trace element signals influencing quality. Thin section petrography shows heavy diagenesis but preserved trace element signals, hinting at potential for extracting valuable palaeoclimate records from these flowstones.

Summary: This study focuses on the diagenetic processes and their impact on reservoir properties in the Kawagarh Formation. It reveals the early calcite cementation occurring prior to compaction and fault-related hydrothermal dolomitization. The research provides valuable insights into burial history, fluid influx, and reservoir characterization, which is crucial for hydrocarbon exploration.

Summary: This study investigates the relationship between fossil preservation and sedimentary environment in the Middle Member of the Tlayua Formation in Mexico. The results suggest that the preservation of fossils was influenced by the deposition of volcanic-clastic layers and the presence of algal mats under anoxic conditions. Two generations of feldspars were identified, with different formation ages.

Summary: Studies have improved our understanding of preservation at the Crato fossil Lagerstatte. The high degree of preservation is a result of mineralization through diffusion of ions and bacteria envelopment, mainly pyritization. However, intense weathering can diminish or obscure morphological fidelity, and little attention has been paid to post-diagenetic processes.

Summary: Research shows that corals adapt to different depths and produce specific skeletal morphologies as ambient light decreases, attributed to physiological feedback between corals and symbiotic algae. Experimental transplantation reveals corals partially adapt and exhibit depth-specific properties. In mesophotic depths, corals have enriched organic matrices and overexpress transcripts encoding biomineralization tool-kit structural proteins.

Summary: This study examined natural moulds and co-occurring aptychi of Hoploscaphites constrictus crassus from the upper Maastrichtian of Poland, identifying growth marks for the first time on these specimens to reconstruct the ontogenetic stages of the shell and aptychus. The growth rate of H. c. crassus was found to accelerate rapidly at the beginning of body chamber formation and then decelerate, with a maturity age of five years tentatively estimated. The role of the aptychus as a protective operculum was rejected for H. c. crassus based on significant mismatches in size and shape during ontogeny.

Summary: One of the most conserved traits in the evolution of biomineralizing organisms is the taxon-specific selection of skeletal minerals. The modern asymbiotic scleractinian coral Paraconotrochus antarcticus in the Southern Ocean forms a two-component carbonate skeleton, with high-Mg calcite in the inner structure and aragonite in the outer structure, similar to the Cretaceous Coelosmilia. This highlights a close phylogenetic relationship and suggests the capability of forming bimineralic structures in scleractinian corals dates back at least 100 million years.

Summary: This study investigated the symbiotic relationship between Carnian corals and zooxanthellae in the Italian Dolomites, revealing potential widespread occurrence of this partnership. The findings suggest that Carnian scleractinian corals exhibited ecological adaptations similar to modern symbiotic corals, indicating that coral-algal symbiosis may have preceded the reef bloom at the end of the Triassic.

Summary: Evolutionary conflicts between viviparous reproductive mode and skeleton shape exist in gastropods, where a spacious canal is needed for embryo delivery but may interfere with the protective function of the shell aperture. Some gastropods have developed flexible embryonic shells to adapt to the squeezing during birth.

Summary: This study investigates the formation and transformation processes of amorphous calcium carbonate (ACC) particles produced by earthworms. In the presence of trace amounts of manganese, the formation and transformation of the particles are more stable. A new model of biocrystallization of earthworm-produced carbonate granules is proposed, highlighting the sensitivity of this process to environmental chemical changes.

Summary: According to isotope exchange experiments on foraminifera tests, the paleoseawater temperature record can be biased by up to 1 degrees C due to grain-boundary diffusion alone. The oxygen isotopic compositions of fossil foraminifera tests provide a continuous proxy record of deep-ocean and sea-surface temperatures over the past 120 million years. Through incubating foraminifera tests in O-18-enriched artificial seawater analogues, it has been shown that the oxygen isotopic composition of translucent calcite tests can be altered at low temperatures through rapid oxygen grain-boundary diffusion without visible ultrastructural changes.

Summary: The biomineralization of fish otoliths is regulated by macromolecules, such as proteins, particularly intrinsically disordered proteins like the Starmaker-like protein. Bioinspired mineralization experiments were conducted to investigate the effects of this protein on calcium carbonate biominerals, considering prior exposure to calcium or carbonate ions. The presence of the Starmaker-like protein significantly affected the morphology and protein distribution within the crystals, highlighting the importance of environmental conditions on its action.

Summary: This study reports the discovery of the first cephalopod statoliths from the Early Cretaceous, filling the gap in the fossil record between Jurassic and Cenozoic forms. The statoliths show a closer resemblance to the Recent Idiosepiidae and are suggested to belong to the basal decabrachians. The robustly developed spur in the Mesozoic statoliths may play a similar role to the wing in Cenozoic and Recent decabrachians. The abundance ratio of statoliths vs fish otoliths also supports a Cretaceous turnover in marine organisms.
