Architecture, Biostratigraphy and Palaeobiogeography of Larger Foraminifera

Foraminifera are one of the most successful groups of fossil organisms through geological times, both from the point of view of diversity and abundance. Forams consist of a single cell (Protozoa)  that commonly develop a complex mineralized shell, which can reach up to 20 cm in size (largest species). The majority of the species are benthic, which live on or within the seafloor sediment, and others are planktonic. Among benthics, the small and structurally simple forms are usually called small benthic foraminifera, while large and structurally complex morphotypes are called larger benthic foraminifera (LBF).

In the geological record, larger benthic foraminifera are abundant in rocks deposited in  the shallow-marine domain of tropical-subtropical climatic areas characterized by stable nutrient-deficient environments. They have a complex architecture and are highly diverse. For all these reasons, the fossil associations of these organisms are highly useful for defining the age of the sedimentary deposits where they are found (Biostratigraphy) and for helping to determine the palaeoenvironment in which they lived (Palaeoecology). Furthermore, studying the global distribution of the different taxa helps to understand the evolution of marine basins over geological time (Palaeobiogeography).

In this area of research, the detailed taxonomical studies are considered to be one of the priority objectives and the basis for reaching a correct identification of taxa, as well as to learn about their evolutionary trends. Precise identifications are key to articulate the later use of larger benthic foraminifera in the different areas of geology.

To date, the team has developed studies dealing with larger benthic foraminifera from the Mesozoic (mainly the Upper Cretaceous) and the Cenozoic (mainly the Paleocene) of several geographic areas in Spain (such as the Baetic Mountains, Pre-Pyrenees, Garraf, Central Depression, and Asturian mountain ranges), Mexico, Portugal, Italy, Greece, Oman and Yemen.
