The Paleogene tectono-sedimentary evolution of the Cuban island is dominated by block tectonics with rotations and strike-slip motion along the northern boundary of the Caribbean plate. The Capdevila Formation, which is the oldest basin fill of the Los Palacios strike-slip basin, preserves this final stage of the Cuban orogeny in western Cuba during the Early Eocene. Petrographic investigations of...
The Shelf and Slope Experimental Taphonomy Initiative (SSETI) deployed a suite of molluscan species in environments covering a range of depths and sediment types in the Bahamas and on the Gulf of Mexico continental shelf and upper slope for 8 years. Taphonomic state rarely correlated with the distribution of biont guilds among environments. The preservable and nonpreservable biont guilds were also...
The Lower Cretaceous Fahliyan Formation, part of the Khami Group, unconformably overlies the Hith Formation and is conformably overlain by the Gadvan Formation in the study area in southern Iran. The Fahliyan Formation is a reservoir rock in Zagros Basin. This formation was investigated by a detailed petrographic analysis in order to clarify the depositional facies and sedimentary environment in the...
A new microencruster of unknown systematic position is described as Perturbatacrustaleini n. gen., n. sp. from the Late Jurassic Plassen Carbonate Platform of the Northern Calcareous Alps and its resediments (p.p. Barmstein Limestone). The labyrinthic interior canal system and marginal openings reveal a possible sponge origin. Differences and affinities to allied taxa such as Radiomura cautica Senowbari-Daryan...
We studied the sclerobiont community associated with organogenic and lithic cobbles from soft bottoms in the Khao Lak coastal area (Andaman Sea) that was damaged by the 2004 tsunami. The 15 cobbles examined originate from grab and hand sampling carried out in the years 2006 and 2007 in the depth range of 4.6–15.2 m. A rich endo- and epibenthos was identified, mainly consisting of algae, foraminifers,...
The succession of the Galala Mountains at the southern Tethyan margin (Eastern Desert, Egypt) provides new data for the evolution of an isolated carbonate platform in the Early Eocene. Since the Late Cretaceous emergence of the Galala platform, its evolution has been controlled strongly by eustatic sea-level fluctuations and the tectonic activity along the Syrian Arc-Fold-Belt. Previous studies introduced...
New data from the Berchtesgaden Alps result in a reconstruction of the Mesozoic-Cenozoic geodynamic history of the Northern Calcareous Alps. The closure of the western part of the Neotethys Ocean started in the late Early Jurassic and is evidenced by the onset of thick clay-rich sediments in the outer shelf area (=Hallstatt realm). The Middle to early Late Jurassic contraction is documented by the...
Round karren represent a typical karst landform in humid regions. Since they only form beneath organic-rich soil and become rapidly destroyed after exhumation, their preservation potential in the geological record is, however, low. Herein, we describe pristine fossil round karren from a late Messinian karrenfeld that is incised into a fault scarp at the northwestern margin of the Polis Graben in NW...
Two new dasycladalean algae are described from the Gosau Group of the Northern Calcareous Alps in Austria. The tiny spicules of Acicularia? weisswasserensis n. sp. were found in foraminiferal wacke- to packstones associated with rudist limestones of the Weisswasser locality (Middle Coniacian), Lower Austria. The small globulous Terquemella? microsphaera n. sp. occurs in marls to marly limestones of...
