of mineralogical, paleontological, sedimentological and absolute K/Ar age of basalts, the profiles were placed into the transition from Paleogene to Neogene and stratigraphic correlation was suggested.
Pikas (Ochotona), small gnawing mammals, related to rabits, range today throughout parts of the Northern Hemisphere, but had a wider distribution during the Pleistocene. The AA. discuss the paleontological remains from northeastern North America
Genetic and paleontological evidence are combining to provide a new and surprising picture of mammalian biogeography in southeastern Alaska. The AA. conclude that brown bears, and perhaps other large mammals, have continuously inhabited
Author provides an overview about the results of palynological, paleontological, geomorphological and archeological investigations concerning the changes in the paleoenvironment in the Carpathian Basin in the last 13,000 years. - (JS)
A geochemical and paleontological reconstruction of paleoproductivity, upwelling intensity and sea surface temperature (SST) off central Chile at 35°S reveals marked changes from the Last Glacial Maximum (LGM) through the Early Holocene. The AA
The polarity reversal patterns, together with earlier vertebrate paleontologic studies, restrict the time span for deposition of the Palm Spring Formation to the middle-late Matuyama chron (2.0-0.75 myr ago). Characteristic directions of least
The pulse of large mammal extinctions at the close of the last ice age was a pronounced ecological catastrophe in the Western Hemisphere. Available paleoenvironmental, paleontological, and archeological data are largely concordant with the overkill
This paper reports the results of field studies on the Late Miocene Baccinello-Cinigiano Basin (Southern Tuscany, Italy). Sedimentological and paleontological analysis of the fossil vertebrate-bearing deposits provided a detailed picture
The research was focused mainly on surveying lake deposits, as well as the morphology and structure of the Pre-Quaternary lake deposits and the morphology and structure of the Pre-Quaternary basement of Lake Balaton. Paleontological investigations
lithostratigraphic sections have been studied. On the basis of the lithostratigraphic evidence, sedimentary architectures and structures, and paleontological data a paleoenvironmental reconstruction is suggested. Finally, the paleoecological meaning of these species
of the core, with new sedimentological, geochronological, and paleontological data, indicate that only 4 deep-lake cycles occurred during this period, apparently correlative with marine oxygen-isotope stages 2, 6, 12, and 16. This interpretation suggests
Washington in conjunction with data from other localities in the Columbia River system and a regional climatic record inferred from geomorphic, palynological, and other paleontological evidence. Using a detailed, well-dated depositional record, they document
Geochemical and paleontological studies of surface sediment to a serie of lakes on progressively older moraines provide baseline information for comparing successive levels of lake sediment cores from older moraines. Results indicate that the time
on morphometric attributes. Historical sources and dendrogeomorphology are useful only for dating very young landslide events. Absolute dating methods and paleontologic classifications (pollen analysis, macroflora, fauna) are preferable for older mass movements
