Rich and well preserved Argentinian taxa made it possible to correlate them with those previously identified species in the coeval sequence in different Tethyan North America, Europe and Middle East localities. This study deals with new information on paleontology and lineages of fourteen Argentinian Ypresian benthic foraminiferal species from the Punta Torcida Formation, lower-middle Eocene (Ypresian-lower Lutetian), Tierra del Fuego Island and Fuegian continental shelf, which belongs to twelve genera: Laevidentalina, Lagenoglandulina, Tollmannia, Tristix, Leticuzonaria, Palmula, Leroyia, Marginulina, Ramulina, Orthokarstenia, Rectuvigerina and Pleurostomella. Ten of the illustrated species are believed to be new: Laevidentalina jannoui, Lagenoglandulina argentinica, Tollmannia argentinica, Leticuzonaria argentinica, Palmula americana, Leroyia argentinica, Marginulina argentinica, Ramulina subornata, Ramulina morsii and Rectuvigerina argentinica sp. nov. The paleoenvironment of the Argentinian taxa would have been a shelf sea of normal salinity, where muds were deposited under low energy and low oxygen conditions, as is suggested by the dominance of infaunal morphotypes and excellent preservation of the tests, whereas intercalated sandstones reflect moderate energy and oxic conditions, bearing microfossil assemblages displaced from shallower settings.

“…In this study, the fourteen recorded Eocene benthic foraminiferal species have been originally from Argentina by Jannou et al [1,2] . It was followed by some other authors from the Southern and Northern Tethyan localities [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] .…”

“…b. The number of species were erected from the Middle East are 119 species: 32/119 species belong to Anan, [7][8][9][10]13,15,17,[23][24][25][26][27][34][35][36][37] 24 species to LeRoy, 4 12 species to Ansary, 50 12 species to Nakkady, 1-3 8 species to Futyan, 29 f. Anan 179 noted that in the late Eocene time in the UAE and surrounding area had been located in the tropical and warmtemperate region based on many faunal environmental elements (presence of keel, accessory apertures, tubular spines in some planktic foraminiferal assemblage and high P/B ratio).…”

“…g. Anan 13 noted that barren dark shale bed that rest on the top Maastrichtian horizon (K/T) in some Tethyan localities: Ain Dabadib (Anan & Sharabi 81 ), Gabal Duwi (Anan 10 ) and also in El Kef section in Tunisia (Keller 101 ) is most probably indicative of low oxygenic level in that time.…”

During the last four decades ago, seventy foraminiferal species have been erected by the present author, which start at 1984 by one recent agglutinated foraminiferal species Clavulina pseudoparisensis from Qusseir-Marsa Alam stretch, Red Sea coast of Egypt. After that year tell now, one planktic foraminiferal species Plummerita haggagae was erected from Egypt (Misr), two new benthic foraminiferal genera Leroyia (with its 3 species) and Lenticuzonaria (2 species), and another 18 agglutinated species, 3 porcelaneous, 26 Lagenid and 18 Rotaliid species. All these species were recorded from Maastrichtian and/or Paleogene benthic foraminiferal species. Thirty nine species of them were erected originally from Egypt (about 58 %), 17 species from the United Arab Emirates, UAE (about 25 %), 8 specie from Pakistan (about 11 %), 2 species from Jordan, and 1 species from each of Tunisia, France, Spain and USA. More than one species have wide paleogeographic distribution around the Northern and Southern Tethys, i.e. Bathysiphon saidi (Egypt, UAE, Hungary), Clavulina pseudoparisensis (Egypt, Saudi Arabia, Arabian Gulf), Miliammina kenawyi, Pseudoclavulina hamdani, P. hewaidyi, Saracenaria leroyi and Hemirobulina bassiounii (Egypt, UAE), Tritaxia kaminskii (Spain, UAE), Orthokarstenia nakkadyi (Egypt, Tunisia, France, Spain), Nonionella haquei (Egypt, Pakistan). Anan 1-5 suggested that the Egyptian and Pakistanian pelagic foraminiferal assemblage indicate an open connection to the Tethys and represents middle-outer neritic environment (100-200 m depth) and shows an affinity with Midway-Type Fauna (MTF). Seven out of the recorded species are believed here to be new: Orbulinelloides sztrakosae, Repmanina mazeni, Psammolingulina bahri, Tritaxia kaminskii, Pseudoclavulina futyani, Pseudoclavulina youssefi and Ammomassilina misrensis. The taxonomic consideration, phylogeny, stratigraphic values, paleoenvironment of these taxa are presented and discussed.
