Mid-chain branched alkanoic acids from "living fossil" demosponges: a link to ancient sedimentary lipids?
Thiel, Volker; Jenisch, Angela; Wörheide, Gert; Löwenberg, Antje; Reitner, Joachim; Michaelis, Walter (Organic geochemistry, 1999)The lipid assemblages of the "living fossil" stromatoporoid Astrosclera willeyana (Great Barrier Reet) and the demosponge Agelas aroides (Mediterranean Sea) were investigated. Large amounts of branched carboxylic acids ... -
Mikrobialith-Porifera Fazies eines Exogyren/Korallen Patchreefs des Oberen Korallenooliths im Steinbruch Langenberg bei Oker (Niedersachsen)
Reitner, Joachim; Böttcher, Gabriele; Brüning, Johannes; Krüger, Björn; Maurer, Jörg; Oppermann, Kurt; Otto, Arnim (Berliner geowissenschaftliche Abhandlungen, 1994)Im oberen Korallenoolith (Oxford-Kimmeridge) von Oker entwickelten sich kleine lagunäre Riffe, deren Gerüst aus Exogyren, Serpeln und großen einzelnen Korallenstöcken gebildet wurde. Die umgebende Fazies besteht aus ... -
Modern cryptic microbialite/metazoan facies from Lizard Island (Great Barrier Reef, Australia) formation and concepts
From shallow water caves of fringing reefs related to continental islands of the Lizard Island Section thrombolitic micritic microbialites were observed. The microbialites exhibit always a light decreasing facies ... -
Monophyly of the Porifera
The monophyly of the Porifera is weil established. According to our hypothesis the Hexactinellida are the adelphotaxon of the Pinacophora (new taxon = Calcarea + Homoscleromorpha + Demospongiae). The Porifera are the ... -
Non-lithistid fossil Demospongiae - origins of their palaeobiodiversity and highlights in history of preservation
Reitner, Joachim; Wörheide, G. (Systema Porifera : a guide to the classification of sponges. Vol. 1: Introductions and Demospongiae, 2002)Available evidence suggests that the first demosponges occur in the Late Proterozoic, with forms characterized by bundles of long monaxonic spicules. In the Middle Devonian the first modern forms of Dendroceratida, ... -
Oldest entirely preserved sponges and other fossils from the Lowermost Cambrian and a new facies reconstruction of the Yangtze platform (China)
Steiner, M.; Mehl, D.; Reitner, Joachim; Erdtmann, B.-D. (Berliner geowissenschaftliche Abhandlungen, 1993)Eine Faziesrekonstruktion W1d Korrelation obersinischer-unterkambrischer Schichten der Yangtze-Plattform (Südchina) wird vorgestellt. Dabei wird zwischen geschütztem Becken, Schwelle W1d tiefem Becken unterschieden. Die ...
