    Details
    ISSN: 1476-4687

    Notes: [Auszug] Organic-walled fossils of Proterozoic planktonic microorganisms are preserved in a wide variety of sedimentary rocks, ranging from lagoonal mudstones to distal turbiditic shales and greywackes. Microfossil assemblages can be correlated with sedimentary environments, permitting the palaeoecological ...

    Notes: [Auszug] Phosphatized microfossils in the Ediacaran (635–542 Myr ago) Doushantuo Formation, south China, have been interpreted as the embryos of early animals. Despite experimental demonstration that embryos can be preserved, microstructural evidence that the Doushantuo remains are embryonic and ...

    Notes: [Auszug] The disappearance of iron formations from the geological record ∼1.8 billion years (Gyr) ago was the consequence of rising oxygen levels in the atmosphere starting 2.45–2.32 Gyr ago. It marks the end of a 2.5-Gyr period dominated by anoxic and iron-rich deep oceans. However, ...

    Notes: [Auszug] ON my first trip to London, 25 years ago, I chanced to see Ingrid Bergman in a West End production. She flubbed numerous lines; I was enchanted. It would have been hard not to be won over, because Bergman radiated an unmistakable delight in the encounter with play and audience, and joy in the ...

    Notes: [Auszug] THE fossil record shows a dramatic radiation in animal forms in the latest Protero-zoic and early Cambrian epochs, the so-called Cambrian Explosion. But molecular clock1'2 and developmental3 arguments instead favour much earlier splitting of invertebrate lineages. These differing results ...

    Notes: [Auszug] Studies of the taxonomic diversity of Phanerozoic invertebrates have shown a pattern of changes in diversity through time, and that this pattern reflects an evolutionary phenomenon strong enough to overcome the presumed biases of the fossil record1. Q-mode factor analyses of marine metazoa further ...

    Notes: [Auszug] The end of the Proterozoic Eon was a time of pronounced biological, biogeochemical, climatic and tectonic change. New bio- and chemostratigraphic data provide an improved framework for stratigraphic correlation, making possible a deeper understanding of latest Proterozoic Earth history and ...

    Notes: [Auszug] ... if my theory be true, it is indisputable that before the lowest Silurian stratum was deposited, long periods elapsed, as long as, or probably far longer than, the whole interval from the Silurian to the present day; and that during these vast, and quite unknown, periods of time, the world ...

    Notes: [Auszug] A HERD of hadrosaurs grazes calmly, apparently unconcerned by a nearby tyrannosaur. Suddenly, a fireball streaks across the sky; there is a huge explosion, a conflagration erupts and a curtain of darkness descends across the landscape. In the six-month night that follows, the dinosaurs all die, as ...
