GENERAL INFORMATION 1. Title of Dataset: Supplement Data 1: Species occurrences per sample at ODP Site 1260 2. Author Information: Corresponding Investigator Name: Mathias Meunier Institution: University of Lille Email: mathias.meunier@univ-lille.fr Co-investigator 1 Name: Taniel Danelian Institution: University of Lille Email: taniel.danelian@univ-lille.fr DESCRIPTION As part of a taxonomic work, we specified the stratigraphic distribution of 15 new middle Eocene radiolarian species (siliceous zooplankton), as well as three species described in early radiolarian studies. The dataset is thus composed of one file named "Supplement_Data_1.cvs", which is an occurrence table including species occurrences per sample (N=55) at ODP Site 1260 (western equatorial Atlantic Ocean). VARIABLES - Depth (rmcd): Revised composite depth assigned to the sample, in meter (see Westerhold and Röhl, 2013) - Age (Ma): Age of the sample in million years (see Westerhold and Röhl, 2013) - Hole-core-section-interval (cm): Name of the sample according to its position in the core Abbreviation used: x = The species is represented by at least one specimen in this sample REFERENCES Westerhold, T., and Röhl, U., 2013, Orbital pacing of Eocene climate during the Middle Eocene Climate Optimum and the chron C19r event: Missing link found in the tropical western Atlantic: Geochemistry, Geophysics, Geosystems, v. 14 (11), p. 4811–4825.
