Morphometric data for a new species of fossil planktonic foraminifera, Globigerinoides rublobatus n. sp, from IODP Site U1483A (NERC Grant NE/L002485/1)
Morphometric data, produced and used, to describe Globigerinoides rublobatus n. sp., a new species of fossil planktonic foraminifera from the Pleistocene Indian Ocean. We used image analysis and morphometry of 860 specimens from International Ocean Discovery Program Site U1483 in the tropical Indian Ocean to document morphological variability in the new species and related taxa.

Data Quality
A total number of 860 specimens of planktonic foraminifera, representing the new species Globigerinoides rublobatus n. sp. and its two potential sister taxa (Globigerinoides conglobatus and Globigerinoides ruber), were measured for morphometric analysis. All picked foraminifera were positioned in umbilical view and photographed with the use of a light microscope, equipped with a digital camera. Morphometric data acquisition was conducted in the Image Pro software, using its standard functions for extracting dimensional data from images of photographed objects. The software was configured to ignore any internal holes (e.g. apertures etc.) and automatically extract all required measurements from the highlighted objects. Collected data were analyzed in Microsoft Excel software, with the three-variable scatter diagrams plotted using Scatterplot3D_2.1 Excel workbook by Doka (2013).
