Abstract: Within the Maastrichtian-Eocene transition in some localities in the Tethys, ten trends of accelerated evolution are recognized within twenty species belong to eight benthic foraminiferal genera: Siphogaudryina, Textularia, Pseudoclavulina, Pyramidulina, Frondicularia, Hopkinsina, Gyroidinoides and Angulogavelinella. Three out of the identified species are treated here to be new: Textularia haquei, Pyramidulina leroyi and Hopkinsina haquei. These lineages marked by changes in the morphology of the foraminiferal test, throughout the number, size and shape of chambers, ornamentation, size and position of aperture, suture and umbilicus. The identified Maastrichtian-Eocene species in this study are recognized in different localities in the Tethys: USA, France, Italy, Tunisia, Egypt, Jordan, UAE, Qatar and Pakistan.
