In: Harries PJ, ed. High-resolution approaches in stratigraphic paleontology: topics in geobiology series. Vol. 21. 421–437.The U.S. Geological Survey, in cooperation with the U.S. Air Force Civil Engineer Center, collected borehole geophysical data and completed simple aquifer tests to estimate the thickness and hydraulic properties of surficial deposits. The purpose of data collection was to create generalized contour maps of Pierre Shale elevation and surficial deposit thickness within and near Ellsworth Air ...carbonaceous shale, and thin coal beds. In much of the area surrounding Coalmont and to the south, the middle member is in unconformable contact with the underlying Cretaceous Pierre Shale. In outcrops north of Coalmont and in drill holes to the east, Hail (1968) recognized three units in the middle member (fig. SN-5): aThe depth to the Pierre Shale along the transects ranged from 0.0 to about 19.8 meters, and the mean and median depths were about 6.1 and 5.6 meters, respectively. The elevation of the Pierre Shale and thickness of unconsolidated deposits generally increased with land-surface elevation from south to north; however, some transects displayed ...

Comparative analysis of niche environments like methane cold seeps in the WIS is limited by the temporally and spatially constrained distribution of seep environments in the Campanian Pierre Shale. Thus, there are few studies focusing on foraminiferal assemblages from either seep or non-seep deposits within the Pierre Shale (e.g., Mello, …

The Pierre Shale is a dark gray clayey to silty mudstone that is exposed in large parts of the Northern Great Plains (Gill and Cobban 1966).It is time equivalent to the Bearpaw Shale in northern and western Montana, Alberta, Saskatchewan, and possibly Manitoba (depending on reference, e.g., Bamburak and Nicolas 2009).It is Campanian to Maastrichtian in age.

The thick Pierre shale was also bent upward under the present site of Boulder. Active mountain building continued throughout the remainder of Tertiary and Quaternary time. It is probable that the Rockies attained their greatest height in the early Tertiary Period, about 45 million years ago. Those peaks were later lowered by erosion.

Styxosaurus was a large elasmosaur, with a long neck measuring about 5.25 metres (17.2 ft) in total. [4] [7] It reached 10.5 metres (34 ft) in length and 2.3 metric tons (2.5 short tons) in body mass. [8] [a] Its sharp teeth were conical and were adapted to puncture and hold rather than to cut; like other plesiosaurs, Styxosaurus swallowed its ...Thermal maturity is commonly assessed by various geochemical screening methods (e.g., pyrolysis and organic petrology). In this contribution, we attempt to establish an alternative approach to estimating thermal maturity with Raman spectroscopy, using 24 North American oil shale samples with thermal maturity data generated by vitrinite reflectance (VRo%) and pyrolysis (Tmax)-based maturity ...The Pierre Shale yields one fossil turtle species, the marine turtle Archelon sp.

We had originally planned to head over the fish quarries of Kemmerer WY, but we decided to stay and explore the Pierre shale and museums for a few days and then dig with Walter a couple more days. We went to the Belle Fourche reservoir (actually the Carlisle shale, not the Pierre) to look for ammonites and shark teeth. ...

Abstract.

Preservation of marine reptile fossils in the Pierre Shale is typically not the best, which means there can be quite some decay from the original form. However, as you're digging marine sediments and the two pieces of bone are obviously procoelous (see diagram below from Wikipedia) mosasaur is the most obvious option.
