The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after creta, the Latin word for the white limestone known as chalk.
The Franciscan Complex or Franciscan Assemblage is a geologic term for a late Mesozoic terrane of heterogeneous rocks found throughout the California Coast Ranges, and particularly on the San Francisco Peninsula. It was named by geologist Andrew Lawson, who also named the San Andreas Fault that defines the western extent of the assemblage. [1]
The area which the museum occupies is situated in the middle of the fossil-bearing strata of the Late Cretaceous Horseshoe Canyon Formation. The Badlands Interpretive Trail is a 1.4-kilometre (0.87 mi) hiking trail northeast to the museum building, and is used extensively by the museum public and school programs.
The Late Cretaceous Epoch, the geologic time epoch 100 to 66 million years ago in Cretaceous Period geochronology, during the late Mesozoic Era The main article for this category is Late Cretaceous .
The Cretaceous is characterized by warm global temperatures caused by the high amounts of carbon dioxide and possibly methane greenhouse gases in the atmosphere. This caused a lack of permanent ice coverage in the polar regions, though the carbon dioxide level dropped between 115 and 66 million years ago (mya), possibly allowing some permanent ice cover.
Even as they grew, erosion was wearing away these Mesozoic Era volcanoes. By Late Cretaceous time, about 70 million years ago, the once-deep granitic rocks began to be exposed at the Earth's surface. By a few tens of millions of years ago, so much of the upper part had worn away that the surface of the ancient range had a low relief of just a ...
At the beginning of the Late Cretaceous, around 100 million years ago, deposition changed to that of chalk, with the deposition of the Chalk Group continuing until the end of the Cretaceous. Chalk was deposited over much of Great Britain, now notably exposed at the White Cliffs of Dover and the Seven Sisters , and also forming Salisbury Plain .
A broken concretion with fossils inside; late Cretaceous Pierre Shale near Ekalaka, Montana. Monument Rocks (Kansas), located 25 miles south of Oakley. By the late Cretaceous, Eurasia and the Americas had separated along the south Atlantic, and subduction on the west coast of the Americas had commenced, resulting in the Laramide orogeny, the early phase of growth of the modern Rocky Mountains.
