We were investigating a report of a mosasaur eroding out of the Weskan member of the Pierre Shale, immediately above the much better known Sharon Springs member. Hardly any people work on collecting fossils out of the Weskan, so we were excited for this opportunity in virtually unexplored country.

A wavelet at a given distance away from a source is visibly smoother and of longer duration than is a wavelet closer to the source. For example, in the Pierre Shale in Colorado, a tenfold loss of amplitude occurs between 10 Hz and 70 Hz, and frequencies above 100 Hz are lost substantially. Many rocks are less attenuating than the Pierre Shale.The Pierre shale sample was extracted from blocks obtained from a Colorado quarry (Cerasi et al., 2017), and further cored to make cylindrical plugs from which fragments were detached and stored in air at room temperature. The sample was glued onto a pin and mounted on a goniometer head with its bedding-plane normal essentially co-aligned with ...Upper Cretaceous Mowry Shale.

Mancos and Pierre Shale. As the sea level rose, it flooded most of the state, depositing the Mancos Shale in the west and the Pierre Shale in central and eastern Colorado. These layers have produced an incredible menagerie of fossils, including coiled, squid-like ammonites, oysters, snails, rare and delicate pterosaur bones, enormous teeth …

The marine Pierre shale, of Late Cretaceous age, on the northern and western flanks of the Black Hills, consists of dark gray shale with some sandy shale and sandstone, and many beds of bentonite. It ranges in thickness from 2,000 to 2,700 feet.

However, for both shales, resonance measurements were representative ...Shale is a sedimentary rock while slate is a metamorphic rock formed from shale. Slate is much more durable than shale due to the metamorphic process it undergoes. Slate and shale are similar in appearance.

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.This paper describes the cranial morphology of two undescribed specimens of the polycotylid plesiosaur Dolichorhynchops bonneri from the Pierre Shale of South Dakota.

The Pierre Shale was originally named by Meek and Hayden (1861) based on outcrops along the Missouri River near Fort Pierre, South Dakota. The unit cov-ers much of South Dakota west of the Missouri River, excluding the Badlands, the Black Hills, and northwestern South Dakota (Gries and Martin, 1985).

Many deflation basins have formed on the Pierre Shale surface to the east of the Colorado Front Range from Denver to Fort Collins. Other pans occur in association with Late Pleistocene desiccation of large pluvial lakes, which was accompanied by deflation in many regions. This led to the migration of dune fields into areas adjacent to the ...The aquifer overlies relatively impermeable claystones of the White River Group, the Cretaceous Pierre Shale, or the shaly chalk and limestone of the Cretaceous Niobrara Formation. The base of the aquifer and the water table generally slope west to east and saturated thickness varies from 0 to greater than 160 m (Fig. 5 ).The Sharon Springs member of the Pierre shale of Cretaceous age, a hard black organic-rich shale similar to the Chattanooga shale, is radioactive throughout central and western South Dakota, most of Nebraska, northern Kansas, and northeastern Colorado. In the Missouri River valley, thin beds of the shale contain as much as 0.01 percent uranium.Assigned as a member of Pierre Shale in eastern ND in Williston basin. No type locality designated.

According to Keefer and Johnson (1997), the Mowry Shale in the Wind River Basin is characterized by two distinct units (fig. 5). The lower part consists of 50 to 150 ft of soft fissile clay-rich shale that has been referred to as the Shell Creek Shale in the adjacent Bighorn and Powder River Basins (Eicher, 1962;Se-rich soils in eastern Montana, western North Dakota, much of South Dakota, Wyoming, Colorado, and Utah, are underlain by a mixture of rock types, but shale is abundant in these areas. Particularly high concentrations of Se occur in soils overlying the Northern Rolling Pierre Shale Plains (USDA, 2006) in central South Dakota.
