Marine biodiversity in space and time: What tiny fossils tell
Biodiversity has been changing both in space and time. For example, we have more species in the tropics and less species in the Arctic and Antarctic regions, constituting the latitudinal diversity gradient, one of the patterns we can see most ...

Proterozoic and early Palaeozoic microfossils in the Karikkoselkä impact crater, central Finland [PDF]
The Karikkoselkä impact crater is located at Petäjävesi (Lat. 62°13.3' N, Long. 25°14.7' E), in central Finland. The crater is filled with impact-generated breccias and redeposited sedimentary rock yielding microfossils.

Micropalaeontology reveals the source of building materials for a defensive earthwork (English Civil War?) at Wallingford Castle, Oxfordshire [PDF]
Microfossils recovered from sediment used to construct a putative English Civil War defensive bastion at Wallingford Castle, south Oxfordshire, provide a biostratigraphical age of Cretaceous (earliest Cenomanian) basal M. mantelli Biozone. The rock used

Fossil biomass preserved as graphitic carbon in a late paleoproterozoic banded iron formation metamorphosed at more than 550°C [PDF]
Metamorphism is thought to destroy microfossils, partly through devolatilization and graphitization of biogenic organic matter. However, the extent to which there is a loss of molecular, elemental and isotope signatures from biomass during high ...

Microfossil-like tourmaline microlites in early Proterozoic nodular chert at Kiihtelysvaara, eastern Finland [PDF]
Many Proterozoic silicified sedimentary carbonates have been reported to contain remains of early micro-organisms. One of these localities in the Fennoscandian Shield is the village of Hyypiä at Kiihtelysvaara in eastern Finland, where a nodular chert ...

Bolboforma from Leg 105, Labrador Sea and Baffin Bay, and the chronostratigraphy of Bolboforma in the North Atlantic [PDF]
The genus Bolboforma, first described by Daniels and Spiegler (1974), is a problematic group of calcareous microfossils. Solbaforma is most probably a planktonic cyst (Rogl and Hochuli, 1976) having protozoan or algal affinities (Poag and Karowe, 1986 ...

Alpine Glacier Reveals Ecosystem Impacts of Europe's Prosperity and Peril Over the Last Millennium
Information about past ecosystem dynamics and human activities is stored in the ice of Colle Gnifetti glacier in the Swiss Alps. Adverse climatic intervals incurred crop failures and famines and triggered reestablishment of forest vegetation but also ...
