The oldest raphe-bearing diatoms: Evidence from the Upper Cretaceous of western and northern Canada

Peter A. Siver et al.

Summary: Diatoms, with their unique siliceous cell walls, are highly successful eukaryotic organisms that inhabit various wet environments. This study reports multiple raphe-bearing freshwater diatoms, including a new species, discovered from Cretaceous fossil localities in Canada. These findings provide evidence for the evolution of the raphe in a freshwater environment during the Cretaceous, and contribute to the understanding of diatom evolution in relation to the geological record.

3D multiscale analysis of the hierarchical porosity in Coscinodiscus sp. diatoms using a combination of tomographic techniques

Othmane Darouich et al.

Summary: A comprehensive analysis using a multiscale approach revealed the hierarchical porosity in Coscinodiscus sp. diatom structures. Different pore sizes, shapes, and connectivities were identified, and evidence of nanometric porosity in the siliceous diatom frustules was provided.

The role of calcareous nannofossils in building age models for Cenozoic marine sediments: a review

Isabella Raffi et al.

Summary: This paper highlights the importance of calcareous nannofossils in geosciences, specifically as a dating tool. Calcareous nannofossils are widely distributed in Mesozoic and Cenozoic carbonate-bearing marine sediments and are routinely used for stratigraphic purposes. Their abundance, taxonomic diversity, rapid evolution, and wide distribution in marine environments make them valuable for relative dating of marine sediments and interpretation of other stratigraphic records.

Global controls on phosphatization of fossils during the toarcian oceanic anoxic event

Sinjini Sinha et al.

Summary: Research on three Lower Jurassic Lagerstatten deposits shows that they were all deposited during the Toarcian OAE period, with fossils mainly preserved through phosphatization. This indicates that these deposits were formed in conditions conducive to phosphatization, suggesting that the TOAE promoted exceptional preservation in marine environments globally.

Revisiting the sedimentary record of the rise of diatoms

Sophie Westacott et al.

Summary: The study examines the burial efficiency of biogenic silica over the past 66 million years using a diagenetic model, finding that changing preservation potential may have affected the primary signal of diatom and radiolarian abundance. The observed increase in diatom abundance in the sedimentary record during the late Cenozoic may be driven by changing preservation potential, with a common driver being the cooling climate system affecting diatom preservation as well as the rise of grasslands and whales.
