An intraformational "flake" conglomerate within the Late Precambrian (700-800 m.y.) Draken Conglomerate of Ny Friesland, Spitsbergen, contains abundant, well preserved microfossils in silicified shards of microbial mats, ...

Gray to black shales from the Kuibis and Schwarzrand subgroups of the Nama Group, South West Africa/Namibia, contain a distinctive, if depauperate, assemblage of organic-walled microfossils. The assemblage is dominated ...

Silicified oolites and pisolites from Bed 18 of the Upper Proterozoic (about 700-800 Ma) Limestone-Dolomite "Series" of the Eleonore Bay Group, central East Greenland, contain a diverse suite of organically preserved ...

Intraspecific encounters were staged between adult male <i>Anolis marcanoi</i> and <i>A. cybotes</i> in order to describe their aggressive behavior. The major component of stationary behavior is the dewlap display, accompanied ...

Careful comparison of naturally derived and synthetic samples of the antheridium-inducing factor of Anemia phyllitidis, AA,,, by TLC, HPLC, NMR and GC-MS measurements allow unambiguous assignment of structure 2 to this ...

We report initial Sr(87)/Sr(86) values from an Upper Proterozoic carbonate succession from Svalbard and East Greenland. This succession, now tectonically separated into three sequences, is thick, relatively continuous, ...

Late Proterozoic organisms must have been diverse and widely distributed, but in general their fossil record is both taxonomically and environmentally limited. Exceptional preservation of Proterozoic fossils is not unknown, ...
