Planktonic Foraminifera) from the Middle- Upper Eocene of Jabal Hafit, United Arab Emirates
Open access e-Journal Earth Science India eISSN: 0974 – 8350 Vol. 11 (II), April, 2018, pp. 122 - 132 http://www.earthscienceindia.info/ Hantkeninidae (Planktonic Foraminifera) from the Middle- Upper Eocene of Jabal Hafit, United Arab Emirates Haidar Salim Anan Gaza P. 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).

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. -

Paleoecology of the Greater Phyllopod Bed Community, Burgess Shale ⁎ Jean-Bernard Caron , Donald A

Jackson Department of Ecology and Evolutionary Biology, University of Toronto, Toronto, Ontario, Canada M5S 3G5 Accepted 3 May 2007 Abstract To better understand temporal variations in species diversity and composition, ecological attributes, and environmental influences for the Middle Cambrian Burgess Shale community, we studied 50,900 fossil specimens belonging to 158 genera (mostly monospecific and non-biomineralized) representing 17 major taxonomic groups and 17 ecological categories. Fossils were collected in situ from within 26 massive siliciclastic mudstone beds of the Greater Phyllopod Bed (Walcott Quarry — Fossil Ridge). Previous taphonomic studies have demonstrated that each bed represents a single obrution event capturing a predominantly benthic community represented by census- and time-averaged assemblages, preserved within habitat. The Greater Phyllopod Bed (GPB) corresponds to an estimated depositional interval of 10 to 100 KA and thus potentially preserves community patterns in ecological and short-term evolutionary time. The community is dominated by epibenthic vagile deposit feeders and sessile suspension feeders, represented primarily by arthropods and sponges. Most species are characterized by low abundance and short stratigraphic range and usually do not recur through the section. It is likely that these are stenotopic forms (i.e., tolerant of a narrow range of habitats, or having a narrow geographical distribution). The few recurrent species tend to be numerically abundant and may represent eurytopic organisms (i.e., tolerant of a wide range of habitats, or having a wide geographical distribution). -
Synchronized Molting in Arthropods from the Burgess Shale Joachim T Haug1*, Jean-Bernard Caron2,3 and Carolin Haug1
Haug et al. BMC Biology 2013, 11:64 http://www.biomedcentral.com/1741-7007/11/64 RESEARCH ARTICLE Open Access Demecology in the Cambrian: synchronized molting in arthropods from the Burgess Shale Joachim T Haug1*, Jean-Bernard Caron2,3 and Carolin Haug1 Abstract Background: The Burgess Shale is well known for its preservation of a diverse soft-bodied biota dating from the Cambrian period (Series 3, Stage 5). While previous paleoecological studies have focused on particular species (autecology) or entire paleocommunities (synecology), studies on the ecology of populations (demecology) of Burgess Shale organisms have remained mainly anecdotal. Results: Here, we present evidence for mass molting events in two unrelated arthropods from the Burgess Shale Walcott Quarry, Canadaspis perfecta and a megacheiran referred to as Alalcomenaeus sp. Conclusions: These findings suggest that the triggers for such supposed synchronized molting appeared early on during the Cambrian radiation, and synchronized molting in the Cambrian may have had similar functions in the past as it does today. In addition, the finding of numerous juvenile Alalcomenaeus sp. molts associated with the putative alga Dictyophycus suggests a possible nursery habitat. In this nursery habitat a population of this animal might have found a more protected environment in which to spend critical developmental phases, as do many modern species today. Keywords: Burgess Shale, Cambrian bioradiation, ‘Cambrian explosion’, Demecology, Molting, Nursery habitats Background can serve as a basis for synecological consideration, e.g., The incompleteness of the fossil record makes recons- predator-prey interactions [4], and the study of larger com- tructing animal ecosystems of the past, a particularly munity and ecological patterns (for example, [5]).
