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

description: 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).
description: 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 <em>G.
 falconensis</em> <em>plexus</em>, 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).
