abysmal

Biological selectivity of extinction,ion of causality. Heritable differences in characters may have predictable consequences in terms of differential species survival. Differences in magnitude and intensity of extinction are insufficient to distinguish background from mass extinction regimes. Biological adaptations may establish links

Shock pressures in igneous processes: Implications for K/T events,sure of about 500 kbar. Such pressures fall off with distance from the magma chamber although jointing, fractures, etc. may act as stress concentrators to extend the radius of formation of shocked minerals as far as a kilometer. Shocked minerals are not to be expected from the magma itself as high t

PACT

Vertical advection from oxic or anoxic water from the main pycnocline as a cause of rapid extinction based on photosynthesis. Waters from the main pycnocline (100–1000 m) or deeper naturally contain decay products from sinking organic matter as a function of the oxidation state of the waters. Such products, in proper concentrations, can inhibit photosynthetic growth or are toxic or debilitating t

Evolutionary crisis within the Ordovician acrotretid inarticulate brachiopods of Poland,pt for three genera of the . line going up to the Silurian and of the . line going on to the Lower Devonian. In Poland, acrotretids are very diversified in Ordovician, especially in the Lower Ordovician/Upper Tremadocian-Llanvirnian), similarly as e.g. in Balto-Scandia (Sweden, Estonia, Leningrad en

The last two coincide in time with what may
