...Shungo Kawagata; Makoto Yamasaki; Richard W. Jordan Abstract Acarotrochus lobulatus, a new species of shallow-water calcareous benthic foraminifer, was found in core material from the meromictic Mecherchar Jellyfish Lake of Palau, northwestern equatorial Pacific. The species belongs to a new genus...

...Jere H. Lipps; Martin R. Langer Abstract Foraminifera occur in the peculiar, meromictic Jellyfish Lake on Mecherchar Island in the Palau Archipelago (Western Caroline Islands). The lake is marine, 30 m deep, and characterized by both oxic and anoxic water layers separated by a distinct chemo...

... earlier Period within the Palaeozoic which some already had referred to as the Eo-Cambrian-one that could well accommodate the first worms and jellyfish-like animals. Some geological tables of strata went so far as to label the immediate pre-Cambrian as an “ Age of worms and jellyfish” even though none...

...Colin D. Sproat; Graham A.

Assuming a yearly probability for such a landslide of 10 −3 , not an unreasonable value for the present stage of the Alps, means that the event will occur on the average every 1,000 years and will be repeated at intervals rarely exceeding...
