title: MORPHOSTATISTICAL ANALYSIS OF MAASTRICHTIAN POPULATIONS OF GUEMBELITRIA FROM EL KEF, TUNISIA
abstract: Three species of Guembelitria with regular triserial arrangement are recognized in the late Maastrichtian, based on biometric measures of specimens from El Kef (Tunisia) and morphostatistical analysis. They are mainly recognized based on their test height and rate of increase in size of the chambers. Guembelitria blowi, nov. sp. is proposed for the short-spired morphotypes that were previously ascribed to Guembelitria trifolia. Guembelitria cretacea Cushman, 1933, is restricted to medium-spired
