Nyctosaurus (meaning "night lizard" or "bat lizard") is a genus of nyctosaurid pterosaur from the Late Cretaceous period of what is now the Niobrara Formation of the mid-western United States, which, during the time Nyctosaurus was alive, was covered in an extensive shallow sea. Some remains belonging to a possible Nyctosaurus species called …The aim of this research study is to understand the physico-chemical interactions between fracturing fluid and formation to investigate the associated geomechanical property changes taking place in the Niobrara shale, a calcium carbonate rich formation, during and after hydraulic fracturing treatments. ….

The Niobrara formation is over 500 feet thick and includes the Fort Hays Limestone at the base and the Smoky Hill Chalk at the top. Subsequent sediment was deposited during the Tertiary period that followed the Cretaceous. The best known formation of this period is the Ogallala, composed of sandy limy rocks often exposed as bluffs like those at ...(Woodford, Bakken, Niobrara, and Eagle Ford) and gas (Mar-cellus, Barnett) as well as less developed hydrocarbon systems with substantial potential (Mancos, Uteland Butte).

ivan adrian wilson Marlstone aggregate concretion, Sault Ste. Marie, Michigan. A concretion is a hard, compact mass formed by the precipitation of mineral cement within the spaces between particles, and is found in sedimentary rock or soil. [1] Concretions are often ovoid or spherical in shape, although irregular shapes also occur.source rocks of the Phosphoria Formation, which contain Type-IIS kerogen, occurred in the Late Cretaceous (80 to 73 Ma [million years]). Gas generation from the cracking of Phosphoria oil reached a peak in the late Paleocene (57 Ma) only in the deepest parts of the province.
