Bridging the extant and fossil record of planktonic foraminifera: implications for the Globigerina lineage

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).

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).
