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.

During the past four decades, the writer has been engaged in paleontology, stratigraphy and paleo-environmental investigations of the planktic and benthic foraminiferal Maastrichtian-Paleogene succession in some Southern Tethyan countries: Tunisia, Egypt, Jordan, UAE, Pakistan, and some Northern Tethyan countries: Spain and France (Figure 1). Most of the species have been erected from Egypt (one benthic genus, one planktic species, one recent species and many benthic foraminiferal species and subspecies, and also 17 species from UAE (Figure 2), and the other species from the other countries in the Southern and Northern Tethys. The taxonomic consideration and stratigraphic implication of the erected taxa are also presented and discussed.

1996 Ornatanomalina sp. Anan²⁸, p. 154, fig. 4. 10.

2011a Ornatanomalina ennakhali Anan², p. 63, pl. 3, fig. 34.

Remarks: This Ypresian species is characterized by its discoidal test, weakly trochospiral in early stage but planispiral in the most later coiling final whorl with acute but semi lobulate periphery, as well as randomly arranged discontinuous ribs on the six to seven chamber surface ended by depressed sutures and equatorial aperture. It differs from the type species O. geei and its subspecies Ornatanomalina geei compressa and other six species of Haque^32,73 from Pakistan (O. crookshanki, O. c. rugosa. O. glaessneri, O. hafeezi, O. elegantula and O. pustulosa) by its discontinuous ribs, not rounded periphery and lacking the radial median ridges across the chamber surface. Loeblich & Tappan⁶ considered the Pakistanian genus Ornatanomalina Haque (1956) as a senior synonym of Saudella Hasson⁷⁸ from Saudi Arabia and considered O. hafeezi as a junior synonym of O. geei (the type species of the genus Ornatanomalina), which not accepted here. Hewaidy⁷⁹ recorded two species of the genus Ornatanomalina (O. hafeezi and O. rugosa) from the Early Eocene Umm Er Radhuma Formation in Qatar. O. ennakhali Anan was recorded from J. Hafit (UAE).

Numerous chambers (17-20) in the last whorl with deeply incised sutures. The chambers of this species have backward extensions at the acute periphery. E. cherifi is characterized by its backward extensions of the chambers and without intraseptal canal system between the chambers. It differs from the figured form E. leave of Cherif et al.⁸⁰ (p. 52, pl. 4, fig. 18) from the Priabonian of J. Hafit by its backward extensions of the chambers. E. cherifi was recorded from J.

Many authors, i.e. Mintz⁸¹, Rögl⁸², Thomas et al.⁸³, Meulenkamp & Sissingh⁸⁴, Arinobu et al.⁸⁵, Keller⁸⁶ using the Cretaceous-Paleogene paleogeographical maps show that a large eastwest Tethyan Sea extended from the Indo-Pacific Ocean in the east to the Atlantic Ocean in the west. Berggren⁸⁷ suggested that during the Paleogene, the fauna of the Mediterranean and the Indo-Pacific exhibit pronounced similarities, which indicate that the connection between the two areas mentioned by a marine seaway, and the East Atlantic fauna was much more closely related to the fauna than it is today. In western Atlantic a narrow connection between it and Pacific existed. Adams et al.⁸⁸ noted that the continuous marine Paleogene connection between the area occupied by the present-day Mediterranean and the Indian Ocean had been lost by mid Burdigalian (early Oligocene) times when a land bridge connected S. W. Asia to Arabia, which means that the faunas of the Mediterranean and Indo-West Pacific began to diverge. They also added that the final disconnection must have been caused by a general elevation of this region rather than by a global eustatic change. Haynes & Nwabufo-Ene⁸⁹ noted that the Paleocene foraminiferal fauna inNigeria is of Tethyan aspect and shows very close relations to shallow shelf faunas in Libya and North Africa, and also suggest wider Tethyan connections, as far as the Carpathian and Pakistan. Meulenkamp & Sissingh⁸⁴ noted that the Arabian Platform, still largely covered by the sea in Early to Middle Eocene times, was subject to a major regression in the Middle to Late Eocene. In the Early Oligocene, it was almost completely emerged. The sea re-invaded the more central parts of the Arabian Platform in the latest Early to earliest Middle Miocene, but regressed again prior to the late Middle Miocene. Anan⁹⁰ noted that twenty one benthic foraminiferal species were originally erected from the Southern Tethyan (Egypt and Pakistan) were recorded from different localities in Northern Tethys France, Spain, Italy, Hungary).

Some paleogeographic remarks of some diagnostic species in the Maastrichtian-Eocene and recent

Most of the identified species were erected from Egypt (40/70, about 57%), 13 species from UAE (18.5%), 8 species from Pakistan (about 11%), 1 species (about 0.14%) from each of USA, Spain, France, Tunisia, Jordan. Clavulina pseudoparisensis Anan³⁸ originally described from the Qusseir-Marsa Alam stretch of the Red Sea coast of Egypt. Later on, it also recorded by El Deeb³⁹ from the UAE coast of the Arabian Gulf, and also from Jeddah at the east coast of Saudi Arabia of Youssef⁴⁰. Plummerita haggagae Anan³⁴ originally described from the latest Maastrichtian of Duwi section, central Egypt. The closed forms to this species which recorded by some authors (i. e. Ziko et al.⁵⁹, and Keller⁶⁰) have wide geographic distribution in Sinai and central Egypt. The Maastrichtian Spiroplectinella hamdani (Anan¹) was originally described from UAE, and its related species were also recorded from the same stratigraphic horizon in many localities in Sinai, Egypt.

Palmula ansaryi Anan⁷ has wide geographic distribution in Egypt and was described from the Bartonian of many sections in Fayoum area, Greater Cairo, Nile Valley and Sinai, and it seems confined to the Lutetian-Bartonian planktic foraminiferal zones of Berggren & Pearson⁹¹ and equated the homogeneous benthic foraminifera P. ansaryi benthic foraminiferal Zone of Anan⁷. It considered an excellent marker for the Bartonian/Priabonian (Middle/Late Eocene) boundary in Egypt. Hemirobulina bassiounii Anan⁷ originally described from the Bartonian of Fayoum area in Egypt, and later on at the same stratigraphic horizon in J. Hafit, UAE (Anan⁴²). Plectina emiratensis Anan¹³ occurs also in the Bartonian of Jabal Hafit, UAE. Amphimorphina youssefi and Saracenaria leroyi both of Anan⁷ were originally described from the Bartonian of Fayoum area (Egypt), and later on in the Priabonian of J. Malaqet (Anan⁹²). Uvigerinella nakkadyi Anan⁷ originally described from the Bartonian of Fayoum (Western Desert, Egypt), and later on from Bartonian-Oligocene succession of Withr section, south western Sinai of Egypt (Shahin⁹³), and it is also recorded from Priabonian of J. Malaqet, UAE (Anan⁹²). Miliammina kenawyi and Bathysiphon saidi both of Anan⁷ were originally described from the Bartonian-Priabonian of Egypt. Later on, it is also recorded in the Bartonian of J. Hafit (Anan⁸), and also in Priabonian of J. Malaqet (Anan⁹²). Textularia fahmyi Anan⁷ originally described from the Bartonian-Priabonian of many sections in Fayoum and Sinai (Tayiba section), Egypt, and later on from Bartonian-Priabonian of El-Nazia section, Fayoum area of Egypt by Helal (2002). Orbulinelloides arabicus Anan¹³ occurs in the Bartonian-Priabonian sequence of J. Hafit. The genus Orbulinelloides and its species arabicus are recorded, so far, for the first time from Arabia and the Middle East.

The Paleocene-Middle Eocene Orthokarstenia nakkadyi Anan⁶⁵ has wide geographic distribution in the northern and southern Tethys, but under different names by different authors: Siphogenerinoides eleganta (Plummer)⁴⁹ from Egypt (El-Dawy¹²) and Tunisia (Saint-Marc⁶⁸) as well as Rectuvigerina clavata (Franzenau) from France (Sztrákos, 2000). All these forms have the same characters: diagnostic longitudinal costae only in the lower half of the test, but smooth without ornamentation in the upper half test. Ornatanomalina ennakhali Anan² was recorded from the upper Ypresian (late Early Eocene) of Jabal Hafit (UAE). The genus Ornatanomalina and its representatives extends their geographic distribution earlier from Pakistan (Haque³²), later on from Rub' Al Khali Basin of Saudi Arabia (Hasson⁷⁸), Qatar (Hewaidy⁷⁹) and UAE (Anan^19,2), which means a wide geographic distribution of these taxa in the Western Asia. Anan³ noted that the paleogeographic distribution of the genus Ornatanomalina and its species are expanded into many localities in Southern and Northern Tethys, which contradict what previously noted by some authors that this genus appear to endemic to Pakistan. Anan⁹⁰ noted that the six representatives of the Maastrichtian-Early Eocene genus Leroyia (aegyptiaca, glabra, maqfiensis, deserti, ghorabi, tunisica) have wide geographic distribution in the Tethys, from west to east: N. America (USA), Europe (France, Italy), Africa (Tunisia, Egypt), Asia (India).

LeRoy²¹ noted that in certain respects the microfauna of the Esna Shale of Maqfi section exhibits an affinity with the Midway Type Fauna (MTF) of the United States Gulf Coastal area. Murray⁹⁴ noted that arenaceous foraminifera tend to increase in cooler (usually deeper) environments. Berggren⁹⁵ and Berggren & Aubert⁵⁵ considered the faunal assemblage of Maqfi section (here represents the Farafra Bahariya Facies, FBF of Issawi et al.⁹⁶ to be predominantly related to the "Midway-Type Fauna, MTF", middle-outer neritic environment (50-200m). Miller et al.⁹⁷ infer that certain hydrographic properties (low oxygen, high CO₂, low pH, and more corrosive waters) favor the development of agglutinated assemblages.

Keller⁹⁸ noted that general cooling trend between Bartonian-Oligocene indicated by the successive replacement of warm Bartonian surface water species (planktic) by cooler Late Eocene intermediate water species, which indicated by the coexistence of surface, intermediate and deep dwelling species group, suggest that increased thermal gradients developed between the equator and poles nearly coincident with the development of late psychrosphere. Keller et al.⁹⁹ noted that the Middle-Late Eocene boundary marked by expansion of cooler water assemblages and a major extinction event among warmer water species involving 80% of the individuals of the population, or 23 % of the species population. It means that most northern and central Egypt, according to these authors, shows an affinity with the MTF, middle-outer neritic environment (50-200 m). Keller¹⁰⁰ also noted that based on foraminiferal morphotype distributional patterns in the Negev-Sinai fauna (=SF) across the K-T boundary have strong survivorship preference for species of epifaunal habitat. Moreover, Culver¹⁰¹ also noted that the epifaunal species dominated by trochospiral test morphologies and that they are less tolerant than infaunal species to lowoxygen conditions.

Cherif & El Deeb¹⁰² noted that close to the end of Bartonian, the previously arid climates became markedly wetter and seems accompanied by a cooling of the water temperature, and the climatic changes inferred the Hafit area seem widespread, at least in parts of the Middle East. Anan³⁸ noticed warmer environments of the studied Qusseir-Marsa Alam stretch of the northern Red Sea coast (the type locality of Clavulina pseudoparisensis), which favor precipitation of carbonates, and it is probable that such a binding material contains a higher proportion of organic carbonates, helping in constructing more resistant tests after the death of the organisms. Moreover, the Red Sea coast, in general, is dynamically less active than most of the considered Mediterranean localities (Cherif¹⁰³). Hewaidy & Anan¹⁰⁴ interpreted that Duwi section in east central Egypt represents middle-outer neritic environment (50-200m). Cherif et al.⁸⁰ noted that the general eustatic level of the sea during Priabonian times (deep marine sedimentation reaching into neritic depths) was shallower than that of the Rupelian (coralline, reefal, inner neritic facies). Anan & Hamdan¹⁰⁵ noted that an incursion of warm temperate water-mass on the foredeep was sporadic and intermittent throughout the Paleocene of J. Malaqet, UAE.

Loeblich & Tappan¹⁰⁶ noted that the foraminiferal suborder Astrorhizina reinstated for the typical monothalamous agglutinated taxa whose cementing material is solely organic, the suborder Haplophragmiina reinstated for multilocular agglutinated taxa with organic cement and simple to alveolar walls. The suborder Trochamminina is recognized for those with organic cement and simple agglutinated walls, and the suborder Textulariina is restricted to include only those with agglutinated walls containing biogenic calcareous cement, and typically canaliculated. El Deeb³⁹ noticed a relative abnormal high frequency of Textulariacea in Arabian Gulf forms 3.5 % resemble the Qusseir-Marsa Alam stretch of the Red Sea, which may be due to the assumption that in the warmer environments in Arabian Gulf and Red Sea regions. Moreover, the Arabian Gulf is generally a higher energy environment when compared with the coasts of the northern Red Sea and eastern Mediterranean. Anan¹ noted that Maastrichtian benthic foraminiferal species of Qarn El Barr section, UAE (include Spiroplectinella hamdani and Marginulinopsis emiratensis) and some other sections in Iraq, Jordan and Egypt are closest to the Maastrichtian fauna of Nekhl section (Sinai of Egypt). The Maastrichtian chalk of Jiran El Ful section, west of Cairo may indicative to open marine middle-outer neritic environment.

Anan¹⁰⁷ noted that in the Priabonian time in the UAE and surrounding area had been located in the tropical and warm-temperate region based on many faunal environmental elements (presence of keel, accessory apertures, tubular spines in some planktic foraminiferal assemblage, high P/B ratio, rich Miliolids and nummulitids assemblage in some horizons). Schmitz et al.¹⁰⁸ and Speijer et al.¹⁰⁹ noted that the high abundance of pelagic microfossils in central Egypt (NVF) indicated open connections to the Tethys. Issawi & Osman¹¹⁰ noted that deep marine sediments deposited in the northern Egypt during the Cretaceous, whereas gradually becoming shallower and less thick to the coeval lithofacies predominated. Billups & Schrag¹¹¹ noted that the intermediate waters depth cooled during Bartonian and reached minimum temperatures by 40 Ma.

Anan³⁴ noted that the spine-like prolongation of the penultimate chambers of the Plummerita haggagae and other recorded Plummerita spp. in Duwi section are mostly represented warm water environment. The high diversity and abundance assemblage of planktic and benthic foraminifera in the top Maastrichtian chocolate marly bed in Duwi section seems deposited in upwelling of nutrient rich water. Moreover, he also noted that the barren dark shale bed that rest on the top Maastrichtian horizon in some Tethyan localities in Ain Dabadib (Anan & Sharabi¹¹²), Duwi section (Anan⁴¹) in Egypt, and in El Kef section in Tunisia (Keller¹¹³) is most probably indicative of low oxygenic level in that time. Anan⁵⁶ noted that Vaginulinopsis boukharyi is restricted in the Paleocene Tarawan Chalk of Duwi section, which may represents an endemic environment, reflects a lowstand deposition (sea-level fall) in, most probably, the inner neritic environment (about 50m) than middle-outer neritic environment (about 150-200m) of the Dakhla Shale below and Esna Shale above. Anan² noted that the probable environment for the Sinai Facies in the northern Egypt (represented by Abu Zenima section) is outer neritic-upper bathyal (200-400m), which it deeper than the following facies: the North Western Desert Facies (represented by Jiran El Ful), Farafra Bahariya Facies (Maqfi section) and Nile Valley Facies (Duwi section), central Egypt, which are deposited in the middle-outer neritic (75-200m). Anan⁵ noted that due to the high abundance of pelagic Pakistanian foraminiferal assemblage indicate open connections to the Tethys and represents middle-outer neritic environment (100-200m depth) and shows an affinity with MTF.

Detailed studies of the well preserved and diversified Maastrichtian-Late Eocene benthic and planktic foraminifera from many localities in the Northern and Southern Tethys made it possible to improve, clarify and erect seventy species by the present author during last four decades ago. Thirty nine species of them were erected originally from Egypt (about 56 %), 17 species from the United Arab Emirates, UAE (about 24 %), 8 species from Pakistan (about 11 %), 2 species from Jordan, and 1 species from each of Tunisia, France, Spain and USA. One planktic foraminiferal species, 19 agglutinated, 3 porcelaneous, 29 Lagenid and 18 Rotaliid species. Ten species of them are recorded from two or more countries in the Northern (Spain, France, Italy, Hungary) and Southern Tethys (Nigeria, Tunisia, Egypt, Jordan, Iraq, Saudi Arabia, United Arab Emirates, Qatar, Pakistan). The erected pelagic foraminiferal assemblage 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, P. youssefi and Ammomassilina misrensis.

Gratitude expressed to the editor of JMEN, the unknown reviewers for their valuable comments, and also to my daughter Dr. Huda H. Anan for her help in the development of the figures and plates.
