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. -
A Palaeobiological Window Into the Lower Cretaceous Cupido Formation: Puerto México Section, Nuevo Leon, Mexico
Carnets Geol. 18 (8) E-ISSN 1634-0744 DOI 10.4267/2042/68182 A palaeobiological window into the Lower Cretaceous Cupido Formation: Puerto México section, Nuevo Leon, Mexico Felipe TORRES DE LA CRUZ 1 Elizabeth CHACÓN-BACA 1, 2 Yesica Edith GÓMEZ-MANCHA 1 Tomás COSSÍO-TORRES 1 Abstract: A rich geobiological record of Cretaceous biotic and abiotic interactions around the proto- Gulf of Mexico has been preserved in the massive Cupido carbonate platform, i.e., in a sedimentary se- quence that represents a depositional period of approximately 15 Myr. This work documents lateral fa- cies variation on a dip slope reef from a new outcrop in the upper part of the Cupido Formation in the state of Nuevo Leon, Mexico. The measured transect is correlated with a stratigraphic column logged in a nearby section. The preserved fossil biota represents marginal reef facies dominated by abundant rudist shells such as Douvillelia skeltoni, Toucasia sp., Offneria sp., and Amphitrocoelus sp. associated with relatively large colonial corals (with diameters up to 25 cm) like Stelidioseris sp. and to a lesser extent, with stromatoporoids. Benthic foraminifers (miliolids and textularids) with associated dasycla- dalean algae such as Salpingorella sp. and Terquemella spp. dominate the microfossiliferous content in wackestones to packstones. This facies is overlain by a thin (15-30 cm) stromatolite horizon at the upper end of the measured section. This locality represents a new paleobiological and taphonomic win- dow into one of the most extensive carbonate platform system developed along the margin of the Gulf of Mexico during the Cretaceous.

Geology of the Basement Below the Decollement Surface, Sierra De Catorce, San Luis Potosi, Mexico
Geological Society of America Special Paper 340 1999 Geology of the basement below the decollement surface, Sierra de Catorce, San Luis Potosi, Mexico - Miguel Franco-Rubio Facultad de Ingenieria, Universidad Autdnoma de Chihuahua, Apartado Postal 1552, Sucursal C, C. I? 31260, Chihuahua, Chihuahua, MLxico ABSTRACT The Sierra de Catorce, one of the most important silver producers in the world, straddles the transitional boundary between the Mesa Central to the west and the Sierra Madre Oriental to the east. Stratigraphically, it consists mainly of marine car- bonate rocks that range in age from Late Jurassic to Late Cretaceous. These rocks are grouped, from top to bottom, into the following lithological units: Caracol, Indidura, Cuesta del Cura, La Peiia, Cupido, Taraises, La Caja, and Zuloaga Forma- tions. Underlying this carbonate rock sequence, and separated from it by a structural discontinuity, is a very thick transgressive section of redbeds that is stratigraphically correlatable to the La Joya Formation. Its age is probably early Late Jurassic. The La Joya Formation redbeds unconformably overlie both the Triassic Huizachal Forma- tion and the upper Paleozoic green beds, which are correlated with the Guacamaya Formation of the Huizachal-Peregrina anticlinorium. This sierra is part of the Mexi- can fold and thrust belt, which is believed to connect to the Cordilleran orogenic belt. This tectonic feature extends along the western parts of North and South America. The evolution of this belt is ascribed to the gradual convergence of the Pacific Ocean and the North and South American plates.

Synoptic Taxonomy of Major Fossil Groups
APPENDIX Synoptic Taxonomy of Major Fossil Groups Important fossil taxa are listed down to the lowest practical taxonomic level; in most cases, this will be the ordinal or subordinallevel. Abbreviated stratigraphic units in parentheses (e.g., UCamb-Ree) indicate maximum range known for the group; units followed by question marks are isolated occurrences followed generally by an interval with no known representatives. Taxa with ranges to "Ree" are extant. Data are extracted principally from Harland et al. (1967), Moore et al. (1956 et seq.), Sepkoski (1982), Romer (1966), Colbert (1980), Moy-Thomas and Miles (1971), Taylor (1981), and Brasier (1980). KINGDOM MONERA Class Ciliata (cont.)
