This paper describes the foraminiferal associations along with presentation of three new agglutinated conical species to construction biozonation framework in Mahallat region central Iran. The stratigraphic distribution benthic foraminifers is used characterize assemblage zones that are ascending order: rotaliids-valvulinids Assemblage Zone, alveolinids-coskinolinids and nummulitids-discocyclin...

The Girujan Clay Formation is demarcated as Bangladeshopollenites barishalensis Zone, which equivalent to middle-upper Siwalik sediments of Punjab Basin. mangrove and coastal palynotaxa present in this formation indicate that these have been deposited under the delta condition a supratidal environment. considered be Mio-Pliocene age. DupiTila recognized here Corrugatisporites sp. Zone. This Nam...

The Gurpi, Tarbur and Sachun formations have been investigated in the studied section in the Fars Province, in order to determine their sequence stratigraphy. On the basis of done studies on the cores of borehole, four main microfacies have been recognized in four stratigraphic sequence deposited during the Campanian to Maastrichtian. The lowermost sequence, was deposited in the early Campanian...

AbstractThe Aitamir Formation is divided into two members the lower sandstone and the upper shale. 32 genera and 57 species of foraminifera have been recognized. According to identified foraminifera Rotalipora appenninica Interval Zone, Rotalipora globotruncanoides (Rotalipora brotzeni) interval zone and Whiteinella aumalensis-Dicarinella canaliculata assemblage zone are proposed and a l Albian...

Reservoirs exhibit gradients in conditions and resources along the transition from lotic to lentic habitat that may be important to bluegill ecology. The lotic-lentic gradient can be partitioned into three functional zones: the riverine, transitional, and lacustrine zones. We measured catch frequency and length of bluegills (Lepomis macrochirus) captured along the periphery of these areas (i.e....

Recently, some new tetrapod fossils were collected along the Yellow River in Shanxi Province. From the Member I of the Tongchuan Formation at Baidaoyu in Liulin County, at least one species of Parakannemeyeria, and one new species of Sinokannemeyeria, S. baidaoyuensis, are identified. The new species is characterized by prefrontal anterior extension level to posterior margin of postnarial excav...
