Notes on the Ordovician Fossils from Bear Island Collected Du Ring the Swedish Expeditions

D uring his Arctic Expedition in the summer of 1898 A. G. NATHORST 1 succeeded in finding fossils in a limestone of the socalled Heclahook-system of Bear Island, the small inlet lying iso1ated between Norway and Spitzbergen, at about 7 41/2 o N. L. (see map p. 91 ). This Heclahook-system consists of a series of limestone, dolomite, quartzitic sandstone and shale, folded and generally very much ...

Behavioral biology of trace fossils

—The potential of the ichnofossil record for exploring the evolution of behavior has never been fully realized. Some of this is due to the nature of the trace fossil record itself. Equally responsible is the separation of ichnology from the relevant areas of modern behavioral biology. The two disciplines have virtually no concepts, methods, or literature in common. The study of animal behavior ...

the role of russia in transmission of energy from central asia and caucuses to european union

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...

Paleoarchean trace fossils in altered volcanic glass.

Microbial corrosion textures in volcanic glass from Cenozoic seafloor basalts and the corresponding titanite replacement microtextures in metamorphosed Paleoarchean pillow lavas have been interpreted as evidence for a deep biosphere dating back in time through the earliest periods of preserved life on earth. This interpretation has been recently challenged for Paleoarchean titanite replacement ...
