Macrofossils from the Hachikoku Oilfield, Niigata Pref.

Macrofossils from a Late-Glacial Deposit at Cambridge, Massachusetts

Macrofossils were isolated from late-glacial sediments exposed in open section in a building excavation at Cambridge, Massachusetts. The lower portion of the profile contained leaves of three species of herbaceous plant species now generally found in arctic or alpine regions, and fragments of a water beetle belonging to a species that now occurs characteristically in regions of boreal forest. T...

Greenhouse gas emissions from oilfield-produced water in Shengli Oilfield, Eastern China.

Greenhouse gas (GHG) emissions from oil and gas systems are an important component of the GHG emission inventory. To assess the carbon emissions from oilfield-produced water under atmospheric conditions correctly, in situ detection and simulation experiments were developed to study the natural release of GHG into the atmosphere in the Shengli Oilfield, the second largest oilfield in China. The ...

Oldest Known Eucalyptus Macrofossils Are from South America

The evolutionary history of Eucalyptus and the eucalypts, the larger clade of seven genera including Eucalyptus that today have a natural distribution almost exclusively in Australasia, is poorly documented from the fossil record. Little physical evidence exists bearing on the ancient geographical distributions or morphologies of plants within the clade. Herein, we introduce fossil material of ...

Plant Macrofossils from Kirchner Marsh, Minnesota—A Paleoecological Study

Seeds and other plant macrofossils were extracted from cores used previously for pollen analysis, and the results are presented in the style of pollen diagrams. The Zone A macroflora is characterized by abundant Picea (spruce) and Larix (tamarack) needles. The remaining species are widely distributed on swampy lake shores, in silty lakes, or in forest-floor communities. The macroflora contains ...
