Abstract The deep-sea planktonic microfossil record (foraminifera, coccolithophores, diatoms, radiolaria and dinoflagellates) provides a unique resource for palaeobiology. Despite some geographical gaps due to poor regional preservation, and intermittant time intervals lost to erosion, most time periods for each Cenozoic planktonic biogeographical province are preserved. Vast numbers of specimens and numerous deep-sea cores provide abundant material and the opportunity to tightly integrate… Expand
On the accuracy of paleodiversity reconstructions: a case study in Antarctic Neogene radiolarians
Abstract The deep-sea Cenozoic planktonic microfossil record has the unique characteristics of continuously well-preserved populations of most species, with virtually unlimited sample size, andExpand
Triton, a new species-level database of Cenozoic planktonic foraminiferal occurrences
TLDR
This new dataset, Triton, contains >500,000 records and is four times larger than the previous largest database, Neptune, and is an excellent resource for macroecological and macroevolutionary studies, particularly for investigating how species responded to past climatic changes. Expand
Sampling bias and the fossil record of planktonic foraminifera on land and in the deep sea
TLDR
It is demonstrated that raw diversity curves derived from the land-based and deep-sea records are strikingly different, but that they each correlate with the intensity of sampling in their respective environments, and thus are ultimately controlled by the structure of the geological record in each setting.

Comparative quality and fidelity of deep-sea and land-based nannofossil records
Variation in sampling intensity of the geological record has long been suspected to distort our view of the history of life. When the taxonomic diversity of the same widespread group of marineExpand
Pacman profiling: a simple procedure to identify stratigraphic outliers in high-density deep-sea microfossil data
Abstract The deep-sea microfossil record is characterized by an extraordinarily high density and abundance of fossil specimens, and by a very high degree of spatial and temporal continuity ofExpand
Quantifying the deep-sea rock and fossil record bias using coccolithophores
Abstract While many studies show a correlation between observed taxonomic richness and various measures of geological sampling, all have been based on the same record of terrestrial and marineExpand
Cenozoic Planktonic Marine Diatom Diversity and Correlation to Climate Change
TLDR
It is suggested that many living marine planktonic diatom species may be at risk of extinction in future warm oceans, with an unknown but potentially substantial negative impact on the ocean biologic pump and oceanic carbon sequestration. Expand
The Paleocene record of marine diatoms in deep-sea sediments
Abstract. Marine planktonic diatoms, as today's ocean main carbon and silicon exporters, are central to developing an understanding of the interplay between the evolution of marine life and climateExpand
Origin of the Eocene planktonic foraminifer Hantkenina by gradual evolution
Hantkenina is a distinctive planktonic foraminiferal genus characterized by the presence of tubulospines (robust hollow projections) on each adult chamber, from Middle and Upper Eocene marineExpand
Evolution and speciation in the Eocene planktonic foraminifer Turborotalia
Abstract Marine planktonic microfossils have provided some of the best examples of evolutionary rates and patterns on multi-million-year time scales, including many instances of gradual evolution.Expand
