2024 Pierre shale - The U.S. Geological Survey, in cooperation with the U.S. Air Force Civil Engineering Center, investigated the use of surface geophysical methods to delineate the top of the Cretaceous Pierre Shale along survey transects in selected areas within and near Ellsworth Air Force Base, South Dakota. Two complementary geophysical methods—electrical resistivity and passive seismic—were used along ...

 
The Pierre shale outcrops in the northern portion of Sioux and Dawes counties, as shown in Pl. XI. The surface of the formation rises somewhat with the general upward slope of its beds toward the Black Hills uplift, and it is exposed by the erosion which has removed the Tertiary formations over the lowlands extending from the valleys of White ....

As the water level dropped and the sea floor became land, the Pierre Shale (the bottommost rock layer of the Badlands) crumbled into soil and created the Yellow Mounds Formation, so called because of its mustard-like color. By 34 to 37 million years ago, when subtropical forests covered the land, river flood plains created the Chadron Formation ...Fox Hills Formation. The Fox Hills Formation is a Cretaceous geologic formation in the northwestern Great Plains of North America. It is present from Alberta on the north to Colorado in the south.

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 ...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.Cretaceous Pierre Shale is directly related to faulting in the underlying Precambrian rocks. The seismic data show fault displacements of as much as 70 ft in the Cretaceous sedimentary rocks at a depth of 2,130 ft; these displacements disrupt overlying rocks and appear to extend into the lower part of the Pierre Shale.As Canada celebrates its 150th birthday, we're taking the summer to cover some of the most incredible fossils that Canada has contributed to paleontology.
