This study has focused on the systematic paleontology are presented with more emphasis on their modern nomenclatural aspects of 30 benthic and planktic foraminiferal species belonging to 16 genera, were identified from four countries in the southwestern part of Asia (Palestine, Jordan, Iraq and Iran). 15 species of them (~50%) are recorded from the Ypresian-Lutetian of Iran, 10 species (~33%) from the Campanian-Maastrichtian of Iraq, 3 species (~10%) from the Danian-Lutetian of Jordan, only 2 species (~7%) from Maastrichtian of Palestine. Eighteen species of them are belonging to the Suborder Textulariina, 5 to Lagenina, 3 species to Rotaliina, and 4 to Globigerinina. Three species of them are believed here as new: Pseudoclavulina iraqensis, Ramulina irregularis and Ramulina radiata. Two benthic foraminiferal lineages are presented: Verneuilina lineage (Verneuilina iraqensis V. jordanica V. luxorensis lineage), which explained also the evolutionary phenomena "Proterogenesis", and Pseudoclavulina lineage (Pseudoclavulina. iraqensis > P. futyani > P. iranica lineage).
