Biometric data measured on a Miogypsina s.s. population are presented. Twenty-four megalospheric specimens have been obtained by means of a random picking on washing residues of a marl layer sampled in the Samatzai Miocene succession (Southern Sardinia), cropping out along the eastern side of the Plio-Pleistocene Campidano Graben. This succession has been mainly deposited into a neritic marine carbonate environment during the Early Miocene rift phase. M. globulina (Michelotti) has been detected in Sam-1 sample, at a central evolutionary stage of the species. It indicates a reference to a early-middle Burdigalian age, that is confirmed by the overlying planktonic foraminiferal assemblage.
