The Pierre Shale is an organic-rich shale from the Late Cretaceous Period (Campanian and Maastrichtian stages) spanning from Canada and Montana through South Dakota and Colorado, extending as far south as New Mexico (Encyclopedia Britannica, 2015; Patrick et al., 2004). The Pierre Shale Group was deposited in a shallow marine foreland basin ...This chart was created to explain the Stratigraphic Units used for the Type Logs Project. In many cases many of the units that are listed in this chart are considered "informal", i.e. Excello Shale Member is used in many of the Tops for Kansas Wells, but is not listed in the Official Kansas Stratigraphic Units Chart.Eutrephoceras dekayi from the Cretaceous Pierre Shale of South Dakota. Note the involute shell of this species. Specimen is from the collections of the Paleontological Research Institution, Ithaca, New York (PRI 44557). An interactive 3D model of this specimen is immediately below.

The modeling uses the Fourier method to compute the spatial derivatives, and therefore can handle complex geometries and general material-property variability. I verified the results by comparison with the 2D analytical solution obtained for wave propagation in homogeneous Pierre Shale.In a broad sense, "nautiloid" refers to a major cephalopod subclass or collection of subclasses ( Nautiloidea sensu lato ). Nautiloids are typically considered one of three main groups of cephalopods, along with the extinct ammonoids (ammonites) and living coleoids (such as squid, octopus, and kin). While ammonoids and coleoids are monophyletic ...Wieland with the giant sea turtle called Archelon that he discovered in the Pierre shale in South Dakota. Courtesy of the Yale Peabody Mus This photo shows Wieland in his back yard.The lower Pierre Shale represents a time of significant changes in the Cretaceous Western Interior Seaway, resulting from complex interactions of tectonism and eustatic sea level changes. The recognition and redefinition of the units of the lower Pierre Shale has facilitated understanding of the dynamics of the basin.

The gross overall thickness of the shale ranges from 2,200 to 2,800 feet, and completions to date have primarily focused on the lowest of five intervals, with commercial pay of 200 to 300 feet.

The Pierre Shale is a massive formation that underlays many Front Range cities, Denver, and much of the eastern plain of Colorado. This unit was formed by the continued transgression of the interior seaway that flooded eastern Colorado during the Cretaceous period.
