Cretaceous Boundary in Western Cuba (Sierra De Los Órganos)
GEOLOGICA CARPATHICA, JUNE 2013, 64, 3, 195—208 doi: 10.2478/geoca-2013-0014 Calpionellid distribution and microfacies across the Jurassic/ Cretaceous boundary in western Cuba (Sierra de los Órganos) RAFAEL LÓPEZ-MARTÍNEZ1, , RICARDO BARRAGÁN1, DANIELA REHÁKOVÁ2 and JORGE LUIS COBIELLA-REGUERA3 1Instituto de Geología, Universidad Nacional Autónoma de México, Ciudad Universitaria, Delegación Coyoacán, C.P. 04510, México D.F., México; [email protected] 2Comenius University, Faculty of Natural Sciences, Department of Geology and Paleontology, Mlynská dolina G, 842 15 Bratislava, Slovak Republic; [email protected] 3Departamento de Geología, Universidad de Pinar del Río, Martí # 270, Pinar del Río, C.P. 20100, Cuba (Manuscript received May 21, 2012; accepted in revised form December 11, 2012) Abstract: A detailed bed-by-bed sampled stratigraphic section of the Guasasa Formation in the Rancho San Vicente area of the “Sierra de los Órganos”, western Cuba, provides well-supported evidence about facies and calpionellid distribution across the Jurassic/Cretaceous boundary. These new data allowed the definition of an updated and sound calpionellid biozonation scheme for the section. In this scheme, the drowning event of a carbonate platform displayed by the facies of the San Vicente Member, the lowermost unit of the section, is dated as Late Tithonian, Boneti Subzone. The Jurassic/Cretaceous boundary was recognized within the facies of the overlying El Americano Member on the basis of the acme of Calpionella alpina Lorenz. The boundary is placed nearly six meters above the contact between the San Vicente and the El Americano Members, in a facies linked to a sea-level drop. The recorded calpionellid bioevents should allow correlations of the Cuban biozonation scheme herein proposed, with other previously published schemes from distant areas of the Tethyan Domain. -
Memorial to Rudolf Oskar Brunnschweiler 1915-1986 KEITH R
Memorial to Rudolf Oskar Brunnschweiler 1915-1986 KEITH R. COLWILL 26 Wattle Avenue, Beaumaris, Victoria 3193 Australia URSULA B. BRUNNSCHWEILER 7Arkana Street, Yarralumla ACT 2600 Australia Why “Pigeons on the Roof’? asked Rudi Brunnschweiler’s daughters when they saw the title page of their father’s latest spare-time project, the draft of a book subtitled “Memoirs of an Explorer.” The title, he replied, was bor rowed from an old Swiss proverb that admonishes “rather than chasing pigeons on the roof, be content with the spar row in your hand.” No doubt many would have been happy with the sparrow, but not Rudi. He aimed his sights higher, and the challenge this philosophy presented was for him the spice of life, its joy and fulfillment. Rudolf Oskar Brunnschweiler was bom in St. Gallen, Switzerland, on December 12, 1915, the oldest of four children of accountant and pioneer sports pilot Oskar Emmanuel Brunnschweiler and his wife Johanna Martha (nee Vogel), concert pianist; they were citizens of Hauptwil, Canton Thurgau. After his early schooling in Ennenda and Glarus, Rudi entered college at Schiers, from which he matriculated in 1935. He then attended the Federal Technological Institute in Zurich to study civil engineering until mid-1938, when he transferred to the faculty of natural sciences at the University of Zurich. In 1941 he married Emmy (“Micky”) Alwine Kiene. Starting a family in those turbulent war years while still a student took considerable courage. Rudi and Micky’s faith in each other and the future proved to be fully justified, and they shared a happy and adventurous lifetime together. -
Valanginian Knowles Limestone, East Texas: Biostratigraphy and Potential Hydrocarbon Reservoir 81
A Publication of the Gulf Coast Association of Geological Societies www.gcags.org V K L, E T: B P H R Robert W. Scott Precision Stratigraphy Associates, 149 W. Ridge Rd., Cleveland, Oklahoma 74020–5037, U.S.A. ABSTRACT The Lower Cretaceous Knowles Limestone is the uppermost unit of the Cotton Valley Group in the northeastern Texas Gulf Coast. It is the oldest Cretaceous carbonate shelf deposit that is a prospective reservoir. This shallow shelf-to-ramp shoal- ing-up complex is an arcuate lenticular lithosome that trends from East Texas across northwestern Louisiana. It is up to 330 m (1080 ft) thick and thins both landward and basinward. Landward lagoonal inner ramp facies are mollusk wackestone and peloidal packstone. The thickest buildup facies are coral-chlorophyte-calcimicrobial boundstone and bioclast grainstone, and the basinward facies is pelagic oncolite wackestone. The base of the Knowles is apparently conformable with the Bossier/Hico dark gray shale. The top contact in East Texas is disconformable with the overlying Travis Peak/Hosston formations. Porosity resulted from successive diagenetic stages including early marine fringing cements, dissolution of aragonitic bioclasts, micrite encrustation, later mosaic cement, and local fine crystalline dolomitization. The age of the Knowles Limestone is early Valanginian based on a calpionellid-calcareous dinoflagellate-calcareous nan- nofossil assemblage in the lower part and a coral-stromatoporoid assemblage in its upper part. The intra-Valanginian hiatus represented by the Knowles/Travis Peak unconformity correlates with the Valanginian “Weissert” oceanic anoxic event. Possi- bly organic-rich source rocks were deposited downdip during that oceanic low-oxygen event. -
The Late Jurassic Tithonian, a Greenhouse Phase in the Middle Jurassic–Early Cretaceous ‘Cool’ Mode: Evidence from the Cyclic Adriatic Platform, Croatia
Sedimentology (2007) 54, 317–337 doi: 10.1111/j.1365-3091.2006.00837.x The Late Jurassic Tithonian, a greenhouse phase in the Middle Jurassic–Early Cretaceous ‘cool’ mode: evidence from the cyclic Adriatic Platform, Croatia ANTUN HUSINEC* and J. FRED READ *Croatian Geological Survey, Sachsova 2, HR-10000 Zagreb, Croatia Department of Geosciences, Virginia Tech, 4044 Derring Hall, Blacksburg, VA 24061, USA (E-mail: [email protected]) ABSTRACT Well-exposed Mesozoic sections of the Bahama-like Adriatic Platform along the Dalmatian coast (southern Croatia) reveal the detailed stacking patterns of cyclic facies within the rapidly subsiding Late Jurassic (Tithonian) shallow platform-interior (over 750 m thick, ca 5–6 Myr duration). Facies within parasequences include dasyclad-oncoid mudstone-wackestone-floatstone and skeletal-peloid wackestone-packstone (shallow lagoon), intraclast-peloid packstone and grainstone (shoal), radial-ooid grainstone (hypersaline shallow subtidal/intertidal shoals and ponds), lime mudstone (restricted lagoon), fenestral carbonates and microbial laminites (tidal flat). Parasequences in the overall transgressive Lower Tithonian sections are 1– 4Æ5 m thick, and dominated by subtidal facies, some of which are capped by very shallow-water grainstone-packstone or restricted lime mudstone; laminated tidal caps become common only towards the interior of the platform. Parasequences in the regressive Upper Tithonian are dominated by peritidal facies with distinctive basal oolite units and well-developed laminate caps. Maximum water depths of facies within parasequences (estimated from stratigraphic distance of the facies to the base of the tidal flat units capping parasequences) were generally <4 m, and facies show strongly overlapping depth ranges suggesting facies mosaics. Parasequences were formed by precessional (20 kyr) orbital forcing and form parasequence sets of 100 and 400 kyr eccentricity bundles. -

The Jurassic/Cretaceous Boundary and High Resolution Biostratigraphy
GEOLOGICA CARPATHICA, APRIL 2019, 70, 2, 153–182 doi: 10.2478/geoca-2019-0009 The Jurassic/Cretaceous boundary and high resolution biostratigraphy of the pelagic sequences of the Kurovice section (Outer Western Carpathians, the northern Tethyan margin) ANDREA SVOBODOVÁ1, , LILIAN ŠVÁBENICKÁ2, DANIELA REHÁKOVÁ3, MARCELA SVOBODOVÁ1, PETR SKUPIEN4, TIIU ELBRA1 and PETR SCHNABL1 1The Czech Academy of Sciences, Institute of Geology, Rozvojová 269, 165 00 Prague, Czech Republic; [email protected], [email protected], [email protected], [email protected] 2Czech Geological Survey, Klárov 131/3, 118 21 Prague, Czech Republic; [email protected] 3Comenius University, Faculty of Natural Sciences, Department of Geology and Paleontology, Mlynská dolina G.

The Kurovice section consists of allodapic and micrite limestones and marlstones. Identified standard microfacies types SMF 2, SMF 3 and SMF 4 indicate that sediments were deposited on a deep shelf margin (FZ 3), with a change, later, into distal basin conditions and sediments (FZ 1). The sequence spans a stratigraphic range from the Early Tithonian calcareous dinoflagellate Malmica Zone, nannoplankton zone NJT 15 and magnetozone M 21r to the late Early Berriasian calpionellid Elliptica Subzone of the Calpionella Zone, nannoplankton NK-1 Zone and M 17r magnetozone. -
Remarks on the Tithonian–Berriasian Ammonite Biostratigraphy of West Central Argentina
Volumina Jurassica, 2015, Xiii (2): 23–52 DOI: 10.5604/17313708 .1185692 Remarks on the Tithonian–Berriasian ammonite biostratigraphy of west central Argentina Alberto C. RICCARDI 1 Key words: Tithonian–Berriasian, ammonites, west central Argentina, calpionellids, nannofossils, radiolarians, geochronology. Abstract. Status and correlation of Andean ammonite biozones are reviewed. Available calpionellid, nannofossil, and radiolarian data, as well as radioisotopic ages, are also considered, especially when directly related to ammonite zones. There is no attempt to deal with the definition of the Jurassic–Cretaceous limit. Correlation of the V. mendozanum Zone with the Semiforme Zone is ratified, but it is open to question if its lower part should be correlated with the upper part of the Darwini Zone. The Pseudolissoceras zitteli Zone is characterized by an assemblage also recorded from Mexico, Cuba and the Betic Ranges of Spain, indicative of the Semiforme–Fallauxi standard zones. The Aulacosphinctes proximus Zone, which is correlated with the Ponti Standard Zone, appears to be closely related to the overlying Wind hauseniceras internispinosum Zone, although its biostratigraphic status needs to be reconsidered. On the basis of ammonites, radiolarians and calpionellids the Windhauseniceras internispinosum Assemblage Zone is approximately equivalent to the Suarites bituberculatum Zone of Mexico, the Paralytohoplites caribbeanus Zone of Cuba and the Simplisphinctes/Microcanthum Zone of the Standard Zonation. The C. alternans Zone could be correlated with the uppermost Microcanthum and “Durangites” zones, although in west central Argentina it could be mostly restricted to levels equivalent to the “Durangites Zone”. The Substeueroceras koeneni Zone ranges into the Occitanica Zone, Subalpina and Privasensis subzones, the A. -

Fossil Microbial Shark Tooth Decay Documents in Situ Metabolism Of
www.nature.com/scientificreports OPEN Fossil microbial shark tooth decay documents in situ metabolism of enameloid proteins as nutrition source in deep water environments Iris Feichtinger1*, Alexander Lukeneder1, Dan Topa2, Jürgen Kriwet3*, Eugen Libowitzky4 & Frances Westall5 Alteration of organic remains during the transition from the bio- to lithosphere is afected strongly by biotic processes of microbes infuencing the potential of dead matter to become fossilized or vanish ultimately. If fossilized, bones, cartilage, and tooth dentine often display traces of bioerosion caused by destructive microbes. The causal agents, however, usually remain ambiguous. Here we present a new type of tissue alteration in fossil deep-sea shark teeth with in situ preservation of the responsible organisms embedded in a delicate flmy substance identifed as extrapolymeric matter. The invading microorganisms are arranged in nest- or chain-like patterns between fuorapatite bundles of the superfcial enameloid. Chemical analysis of the bacteriomorph structures indicates replacement by a phyllosilicate, which enabled in situ preservation. Our results imply that bacteria invaded the hypermineralized tissue for harvesting intra-crystalline bound organic matter, which provided nutrient supply in a nutrient depleted deep-marine environment they inhabited. We document here for the frst time in situ bacteria preservation in tooth enameloid, one of the hardest mineralized tissues developed by animals. This unambiguously verifes that microbes also colonize highly mineralized dental capping tissues with only minor organic content when nutrients are scarce as in deep-marine environments. Teeth and bones are ofen the only evidence of ancient vertebrate life because of the mineralized nature of tissues. Tere are numerous possibilities for chemical alteration during the transition from the bio- to the lithosphere of which bacterial catabolysis of these tissues and organic matter within the carcass is an important example 1,2.
