The regional stratigraphic and structural setting of the Pierre Shale in the northern Great Plains is summarized from subsurface data.This specimen (SDSMT 452) is was found in the Pierre Shale (Campanian) near the spillway of Elm Lake, Brown County, South Dakota. It was cited and extensively figured in Dale Russell's 1967 benchmark publication (Systematics and Morphology of American Mosasaurs), and is the subject of a new paper currently in preparation.

Its fossils specimens were found in the Niobrara Formation and Pierre Shale Formation in Kansas, Alabama, Nebraska, Wyoming, and South Dakota. What was a Pteranodon's habitat? The Pteranodon lived near the ocean or sea. The area where their fossils were found was covered by a large inland sea.Welcome to the Fossil Forum! I assume you collected at Baculite Mesa? If so (or anywhere in that area) the long cylindrical fossils are Baculites scotti if they are smooth. The outcrop is in the Baculites scotti zone of the Pierre Shale, and 99.9% of the Baculites there are that species. There is a second Baculites, B. texanus, that has strong nodes on the side, but they are very rare compared ...The Fort Morgan 7.5′ quadrangle is located on the semiarid plains of northeastern Colorado, along the South Platte River corridor where the river has incised into Upper Cretaceous Pierre Shale. The Pierre Shale is largely covered by surficial deposits that formed from alluvial, eolian, and hillslope processes operating in concert with environmental changes from the late Pliocene to the present.The Denver Basin aquifer system is composed of Late Cretaceous to Tertiary-age sandstone bedrock aquifers and intervening claystone confining units that occur in the uppermost layers of the structural Denver Basin above the Cretaceous Pierre Shale confining layer.In Hell Creek Formation - dark colored continental beds above the Fox Hills Sandstone and Pierre Shale.

The Pierre Shale was described by Meek and Hayden in 1862 in the Proceedings of the Academy of Sciences (Philadelphia).In general, the Pierre Shale and older Cretaceous rocks are exposed on the north side of the Arkansas River along the study reach (Fig. 2).The Pierre Shale and younger rocks are exposed on the south side of the Arkansas River, except at the downstream end where erosion has removed the overlying Pierre Shale and exposed the Niobrara Formation on both sides of the river.Pierre Shale (Upper Cretaceous) at surface, covers < 0.1 % of this area. Blue-gray to dark-gray, fissile to blocky shale with persistent beds of bentonite, black organic shale, and light-brown chalky shale. Contains minor sandstone, conglomerate, and abundant carbonate and ferruginous concretions. Thickness up to 1,000 ft (305 m).The base of the overlying Pierre Shale is composed of the Burning Brule Member within the Sharon Springs Formation, the former of which is up to 24 m thick (Bertog, 2012). The Burning Brule Member is a particularly organic-rich unit that has produced underground fires, likely due to the oxidation of pyrite, and in the study area, it varies from ...Pierre Shale. The "base" of the Niobrara NSR is Pierre Shale, a gray to black rock that is difficult to see in the western half of the river. Those who visit the eastern half of the river, which is much more difficult to float, may see dark bluffs of the rock. It is also visible if you drive to the intersection of Highway 7 and the river.The Pierre Shale, a thick unit of Upper Cretaceous marine strata, crops out in a belt as much as 20 miles wide that parallels the Front Range in Colorado.

Cheyenne River, which is in a Campanian/Maastrichtian terrestrial horizon in the Pierre Shale Formation of South Dakota.Its type locality is West bank of Missouri River near Bailey Island, which is in a Campanian/Campanian marine shale/shale in the Pierre Shale Formation of South Dakota. Environments: marine (1 collection), offshore (1) Age range: 84.9 to 70.6 Ma. Distribution:The Pierre shale typically shows significantly higher tensile strength under induced swelling pressures which makes it more difficult to induce hydraulic fracture in reservoir shales. Previous studies have shown that higher concentrations of KCl increased the tensile strength of shales. 7 On the other hand, the lower tensile strength observed ...Niobrara Chalk was weathered and opalized in the Valentine phase of the Ogallala Formation. The Niobrara Formation / ˌnaɪ.əˈbrærə /, also called the Niobrara Chalk, is a geologic formation in North America that was deposited between 87 and 82 million years ago during the Coniacian, Santonian, and Campanian stages of the Late Cretaceous.Archelon is an extinct marine turtle from the Late Cretaceous, and is the largest sea turtle ever to have been documented, with the biggest specimen measuring 460 cm (15 ft) from head to tail, 400 cm (13 ft) from flipper to flipper, and 2,200 kg (4,900 lb) in weight. It is known only from the Dakota Pierre Shale and has one species, A. ischyros.The purpose of data collection was to create generalized contour maps of Pierre Shale elevation and surficial deposit thickness within and near Ellsworth Air Force Base (study area).

Specifically, the overall facies distribution of the Sharon Springs ...The Williams Fork Formation is a Campanian (Edmontonian) geologic formation of the Mesaverde Group in Colorado. Dinosaur remains are among the fossils that have been recovered from the formation, most notably Pentaceratops sternbergii,.Other fossils found in the formation are the ammonite Lewyites, neosuchian crocodylomorphs, and the mammals Glasbius and Meniscoessus collomensis.The base of the overlying Pierre Shale is composed of the Burning Brule Member within the Sharon Springs Formation, the former of which is up to 24 m thick (Bertog, 2012). The Burning Brule Member is a particularly organic-rich unit that has produced underground fires, likely due to the oxidation of pyrite, and in the study area, it varies from ...overlies the Pierre Shale throughout the basin and was depos-ited along an eastward-prograding shoreline during the fi nal retreat of the Cretaceous Seaway from northern New Mexico and southern Colorado. The Trinidad Sandstone was deposited in shallow marine, shoreface, and deltaic environments (Pill-more and Maberry, 1976; Billingsley, 1977).Pierre Shale (Late Cretaceous) at surface, covers < 0.1 % of this area. Mostly medium to dark-gray, brownish-gray, and black, fissle clay shale. Locally grades to thin beds of calcareous, silty shale or claystone, marl, shaly sandstone, and sandy shale. Locally contains thin seams of gypsum and sparse selenite crystals. Approx. max thickness ...For Pierre Shale the calculation gives ρ 2 = 6.3 μm/s, while for sandstone a commonly cited literature value of approximately ρ 2 is 10–11 μm/s (Straley et al., 1997). Dunn et al. (2002) have shown that there is considerable variability of ρ 1 and ρ 2 in siliclastic rocks and our computed value is therefore reasonable. Interpretation of ...Oil shale is an organic-rich fine-grained sedimentary rock containing kerogen (a solid mixture of organic chemical compounds) from which liquid hydrocarbons can be produced. In addition to kerogen, general composition of oil shales constitutes inorganic substance and bitumens.Based on their deposition environment, oil shales are classified as marine, lacustrine and terrestrial oil shales.The Pierre Shale in this area had not been systematically collected before, so Gorden and the others were trying to get as much data as possible with each specimen to better define the occurrences of the various species.
