Abstract
Dataset for the biometric study on picked specimens of the planktonic foraminifer Globigerina falconensis. The individuals span the biozones M4 to PT1 from various locations worldwide. All specimens come from cored drill samples from IODP Site U1482, ODP Site 590, Meteor M32. All these data have been used for the paper entitled: Bridging the extant and fossil record of planktonic foraminifera: implications for the Globigerina lineage. Extra 33 samples are from a geological outcrop located in Siena Basin (Italy).

DATA-SPECIFIC INFORMATION FOR: Fabbrini_et_al_PALAEONTOLOGY_Globigerina falconensis_Biometry.csv
Number of rows: 612
Variable List:
- Record ID, number of the individual analysed;
- Locality, collection site of the original sample;
- Biozone, biozone following Wade et al. (2011) indicating the relative age of the sample and individual;
- Sample ID, name of the sample;
- Specimen ID, name of the individual measured;
- Area, surface occupied by the individual; expressed in m^2;
- Diameter, maximum diameter of the individual; expressed in m;
- Roundness, measure of how closely the individual approaches a perfect circle; expressed as ratio between 0-1;
Methods
The specimens have been picked using a stereomicroscope at University College London (UK). All the measurements for the morphometric study were conducted on the entire picked populations of G. falconensis plexus, using the software Image Pro, through the camera QImaging RETIGA-2000R mounted on a light microscope at the Department of Earth Sciences at UCL. The following three parameters have been selected and measured: Area (A) (μm2), Diameter (D) (μm), Roundness (R). This last parameter (Roundness) has been obtained from A and D directly on Image Pro. All data were plotted using the Statistical Software PAST (Hammer et al. 2001).
