  • Foraminifera • Foraminifers Are Found in All Marine Environments
    Foraminifera • Foraminifers are found in all marine environments. Some are adapted to brackish water. There are none in fresh water. Two life modes are recognized: • Benthic . These are forms that live on the sea floor, either on the surface of the sediment (epifauna) or buried in it (infauna). • Planktonic . These are forms which float passively, moved only by currents but capable of vertica migration. Some planktonic foraminifers (their largest dimension on the order of a half-millimeter). Small benthic foraminifers (their largest dimension on the order of a half-centimeter). Some large benthic foraminifers (their largest dimension on the order of a centimeter).

O. Box 1126, Palestine Email: [email protected] ABSTRACT Six species of the planktonic foraminiferal Family Hantkeninidae belonging to the genera namely Cribrohantkenina and Hantkenina are recorded and described from the Middle- and Upper Eocene succession of Jabal Hafit, Al Ain area, United Arab Emirates. The species include Cribrohantkenina inflata, Hantkenina alabamensis, H. compressa, H. australis, H. liebusi and H. primitiva. The three species of Hantkenina named last are recorded for the first time from the UAE. Keywords: Middle Eocene, Upper Eocene, Hantkeninidae species, United Arab Emirates INTRODUCTION The species of the genera Cribrohantkenina and Hantkenina have a worldwide distribution encircling low and mid-latitudes. The appearance of the genus Hantkenina at 49 Ma corresponds with the Early/Middle Eocene boundary, and their extinction at 33.7 Ma denotes the Eocene/Oligocene boundary, while the genus Cribrohantkenina appears only at the Late Eocene (36. 4 Ma-34. 3 Ma) and its extinction denotes the Eocene/Oligocene boundary. Pearson (1993) noted that the genus Hantkenina have a rounded periphery and more globose chambers (e.g. H. alabamensis) and sometimes areal apertures on the chamber face around the primer aperture (=Cribrohantkenina). Coxall et al. (2003); Coxall and Pearson (2006); and Rögl and Egger (2010) noted that the genus Hantkenina evolved gradually from the genus Clavigerinella in the earliest Middle Eocene, contrary to the long- held view that it is related to the genus Pseudohastigerina evolved from Globanomalina luxorensis (Nakkady) in the earliest Early Eocene (base of Zone E2) by the development of a symmetrical umbilical aperture and slightly asymmetrical to fully planispiral test as are the result of changes in the timing of the development processes.

Major events are characterized by the disappearance of giant forms of both Nummulites and Assilina and also of the genus Alveolina and some orthophragminid lineages. Simultaneously, radiate and especi- ally reticulate Nummulites, the N. fabianii lineage, and nummulitids with secondary chamberlets such as Heterostegina and Spiro- clypeus emerged. Based both on first/last occurrence (FO/LO) data and the evolution of these forms and integrating geological in- formation such as field observations, other LBF and planktonic data, a high-resolution stratigraphy of the Bartonian and Priabonian could be established in the frame of the Tethyan shallow benthic zonation (with SBZ zones and newly erected subzones for SBZ 18 and 19 based on the exceptionally rapid evolution of Heterostegina). We distinguish eight Western

  • The Challenger Report As Patellina Campanaeformis Does Not Ferred To
    FOR FORAMINIFERAL RESEARCH 17 The Patellina punctata Terquem (Essai Class. Anim. kerque, 1881, p. 128, pI. 16, figs. 9 a, b) may be a Recent speci- men belonging to P. corrugata, or may be one of the fossil species which occur in the material recorded by Terquem from this area. The figure is not conclusive. The Patellina plicata Terquem of the same paper (p. 72, pI. 8; figs. 9 a, b) is a Trochammina.. The high spired, thick-waned species described by Brady in the Challenger report as Patellina.. campanaeformis does not seem to be a true Pa.tellina. Parker and Jones have given the name Orbitolina annularis to a peculiar form found on the coast of Australia (Ann. Mag. Nat. Hist., ser. 3, vol. 6, 1860, p. 31) later referred to Patellina corrugata (Carpenter, Parker and Jones, Introd. Foram., 1862, p. 230, pI. 13, figs. 16, 17). These are large specimens with annular chambers and need further study. They have been re- ferred to as Patellina corfugata, var. annularis by Heron-Allen and Earland (Rept. British Antarctic Exped. Zoology, vol. 6, 1922, page 198). They mention that their New Zealand speci- mens represent transition stages. In my own New Zealand col- lections, there are specimens in which the divisions into cham- bers are few, but no annular chambers occur. With these are specimens of P. advena Cushman. Chapman figures a form with apparently annular chambers, but the early portion with sub- globular chambers (Journ. Quekett Micr. Club, ser. 2, vol. 10, 1907, p. 134, pI. 10, fig. 7). The fossil and Recent members of this group which are found in the Australian region seem particularly worthy of special study.
