This quantity provides a collection of unique stratigraphic and sedimentologic investigations of the Eocene eco-friendly River Formation of Wyoming, Colorado and Utah, one of many world’s most desirable terrestrial data of lacustrine and alluvial deposition in the course of the warmest section of the early Cenozoic. Its twelve chapters surround the wealthy and sundry list of lacustrine stratigraphy, sedimentology, geochronology, geochemistry and paleontology. Chapters 2-9 offer specific member-scale synthesis of eco-friendly River Formation strata in the better eco-friendly River, Fossil, Piceance Creek and Uinta Basins, whereas its ultimate chapters deal with its enigmatic evaporite deposits and ichnofossils at huge, interbasinal scale.

Warren Allmon, David J. Bottjer's Evolutionary Paleoecology PDF

Essentially the most vital questions we will be able to ask approximately lifestyles is "Does ecology topic? " such a lot biologists and paleontologists are informed to reply to "yes," however the distinctive mechanisms wherein ecology concerns within the context of styles that play out over hundreds of thousands of years have by no means been solely transparent. This ebook examines those mechanisms and appears at how historic environments affected evolution, targeting long term macroevolutionary adjustments as visible within the fossil list.

Where duplicate samples were run, averages weighted according to standard deviation were used. 1). Microlaminated kerogen-rich mudstone Laminated, organic-rich mudstone is the dominant lithofacies of the Rife bed, though it is also found to a lesser extent in the Scheggs bed. The mudstone is generally dark-brown to black in color. Discrete, rhythmic, variegated laminations are μm to mm in scale, and planar parallel (Fig. 4a). Interlaminations (mm- to cm-scale) of tan siltstone, tuff, and chert are found infrequently within sections.

Likely during the inception of subsidence and the formation of Lake Gosiute there were many of these embryonic lakes in the southern portion of the Greater Green River Basin which later expanded and coalesced as subsidence deepened the Uinta trough (Fig. 8). Basin-scale stratigraphic stacking patterns observed in the Luman cross-section support this interpretation (Fig. 7). The cross-section reveals that in the lower half of the Fig. 8 Box model interpretive diagrams illustrating paleogeography and sedimentary facies during deposition of (a) lower Luman Member, and (b) upper Luman Member 2 Initiation of Eocene Lacustrine Sedimentation in the Greater Green River Basin… Luman Member paludal facies dominate the depositional style of the basin with small, isolated ponds and lakes fed by axially draining feeder streams punctuating the vertical section.
