Dataset of calcareous nannoplankton and smaller benthic foraminifera from a nummulitic accumulation (Bartonian, Eocene, Transylvanian Basin, Romania)

Abstract

Data reported herein, have been obtained from the micropaleontological analysis of the middle Eocene (Bartonian) calcareous nannoplankton and smaller benthic foraminifera record from nine representative areas located in the Gilău and Meseș area from the Transylvanian Basin, Romania. The micropaleontological data comprise raw species counts (Tables 1, 2), relative abundances (Tables 3, 4) and ARCSIN-normalized values used to perform multivariate analysis (Tables 5, 6) for both calcareous nannoplankton and smaller benthic foraminiferal assemblages. The ARCSIN-normalized datasets (Tables 5, 6) include only taxa with more than ~2% relative abundance (Table 5, calcareous nannoplankton) and only taxa having more than 1% relative abundance (Table 6, smaller benthic foraminfiera ). The calculated abundance data of smaller benthic foraminiferal taxa, groups and microhabitats, the calculated benthic foraminifera dissolved oxygen index – BFOI are presented in Table 7, whilst the diversity indices of smaller benthic foraminifera are included in Table 8. Same background color in each table represents the same outcrop and the samples are stored in case of each outcrop in stratigraphic order (samples with the same style – italic and bold – belong to the same stratigraphic level). In the case of the calcareous nannoplankton datasets (Tables 1, 3, 5) the samples written with red had less than 50 specimens and they were excluded from the statistical analysis
