    The book also approaches the ecology of river algae not to mention the ecological factors influencing abundance, distribution and diversity of river benthic algal communities and their use as bio-indicators, providing an up-to-date information on taxonomy, ecology, methodology and uses, and a great source of research to everyone interested in. Description: This 50 million year old, Eocene-Era fossil fish comes from one of the world's famous Laggerstatten, the Green River Formation in Wyoming. A small portion of the fish fossils from Green River exhibits such fine preservation.

    The Green River Formation contains a vast array of saline minerals that includes: shor-tite Na 2Ca 2(CO 3) 3, northupite Na 3Mg(CO 3) 2Cl, pirssonite Na 2Ca(CO 3) 2. 2H 2O, gaylusite Na 2Ca(CO 3) 2. 5H 2O, nahcolite NaHCO 3, thermonatronite Na 2CO 3.H 2O, wegscheiderite Figure 1: Green River Formation and location of sample Size: KB. pp / staton, t. w., / the fauna of the cannonball marine member of the lance formation; corals from the cannonball marine member of the lance formation; lower miocene foraminifera of florida; the origin of th e faults, anticlines and buried “granite ridge” of the northern part of the mid-continent oil and gas field; the use of.
