Canada The Munising Group or Formation is a 1,700 feet (520 m) thick, white to light grey [ 1 ] Cambrian sedimentary unit that crops out in Michigan and (to a lesser extent) Ontario . At one end of its extent, it comprises a basal conglomerate overlain by the Chapel Rock Member and the Miners Castle Member; elsewhere, it comprises the Eau ...
The Devonian Catskill Group or the Catskill Clastic wedge is a unit of mostly terrestrial sedimentary rock found in Pennsylvania and New York.Minor marine layers exist in this thick rock unit (up to 10,000 feet (3,000 m)).

Early Eocene proxy ensemble data from fossil localities showing (a) MAT and (b) MAP estimates with the Margaret Formation indicated with (3) During the Early Eocene, the climate of much of northern North America was warm and wet, with mean annual temperatures (MAT) as high as 20 °C (68 °F), mean annual precipitation (MAP) of 100 to 150 centimetres (39 to 59 in), mild frost-free winters ...
Dunvegan Sandstone. The Dunvegan Formation is composed of marine, and deltaic sandstone with thin shale interbeds in the Peace River Country. East of Dunvegan, Alberta it is of marine origin, and in its western reaches in British Columbia it was deposited in a continental facies, where the sandstone becomes more conglomeratic.
Gething Formation is a stratigraphic unit of Lower Cretaceous age in the Western Canada Sedimentary Basin.It is present in northeastern British Columbia and western Alberta, and includes economically important coal deposits.
The Newark Supergroup consists largely of poorly sorted nonmarine sediments; typical rocks are breccia, conglomerate, arkose sandstone, siltstone, and shale. [3] [4] Most of the strata are red beds that feature ripple marks, mud cracks, and even rain drop prints; dinosaur footprints are common, though actual body fossils are very rare. [4]
