Bacterial Spores Survive Simulated Meteorite Impact,oorganisms, embedded in rocks, have to cope with three major steps: (i) escape from the planet by impact ejection, (ii) journey through space over extended time periods, and (iii) landing on another planet. Whereas step two of the scenario, the survival in space, has been studied in depth in space e

Comparison of Bosumtwi Impact Crater (Ghana) and Crater Lake Volcanic Caldera (Oregon, USA): Implic areas, leading to new habitats that are initially barren. These events are followed by variable periods of recovery of the biota. Impact craters and calderas are rather similar in form, structure and internal geometry. Furthermore, they are commonly sites of crater lakes. In order to shed light on

Paleobiologic Effects of the Late Cretaceous Wetumpka Marine Impact, a 7.6-km-Diameter Impact StrucLate Cretaceous (late Santonian to early Campanian). Water depths for the epicenter of this event are estimated to have been 30 to 100 m, and this feature probably formed within ∼ 25 km of the local barrier-island shoreline. All indications are that this impact would have been a locally devastating

,The Sweet Aftermath: Environmental Changes and Biotic Restoration Following the Marine Mjølnir Impaositional conditions. The stratified water-masses contained typically relatively rich, but low diversity, nectonic faunas and marine microfloras above the pycnocline. In contrast the benthic faunas contained only a few bivalve species and low diversity communities of foraminifera. At the time of the

Continental Vertebrate Extinctions at the Triassic-Jurassic and Cretaceous-Tertiary Boundaries: a Certiary (K/T) mass extinctions, a comparison of extinction patterns among continental vertebrates reveals significant differences between these two events. There is no discernible size factor at the Tr/J boundary, whereas the K/T extinction is marked by the disappearance of all large land vertebrate
