    Microfossils, a key to unravel cold-water carbonate mound evolution through time: Evidence from the eastern alboran sea

    Cold-water coral (CWC) ecosystems occur worldwide and play a major role in the ocean's carbonate budget and atmospheric CO2 balance since the Danian (~65 m.y. ago). However their temporal and spatial evolution against climatic and oceanographic variability is still unclear. For the first time, we combine the main macrofaunal components of a sediment core from a CWC mound of the Melilla Mounds...

    Fossil and genetic evidence for the polyphyletic nature of the planktonic foraminifera ‘Globigerinoides’, and description of the new genus Trilobatus

    In: PLoS ONE, 2015, vol. 10, no. 5, p. e0128108

    Planktonic foraminifera are one of the most abundant and diverse protists in the oceans. Their utility as paleo proxies requires rigorous taxonomy and comparison with living and genetically related counterparts. We merge genetic and fossil evidence of “Globigerinoides”, characterized by supplementary apertures on spiral side, in a new approach to trace their “total evidence phylogeny”...
