The Waynesburg Formation is a coal, sandstone, and siltstone geologic formation in West Virginia and Pennsylvania. It preserves fossils dating back to the Permian period.
The Freeport Formation is a geologic formation in Pennsylvania and Ohio. It preserves fossils dating back to the Late Pennsylvanian period. It is within the Allegheny Group.
The Albemarle Group is a geologic group in North Carolina composed of metamorphosed mafic and felsic volcanic rock, sandstone, siltstone, shale, and mudstone. It is considered part of the Carolina Slate Belt and covers several counties in central North Carolina. It preserves fossils dating back to the Ediacaran period in the Floyd Church member.
The Patapsco Formation is a geologic formation of varigated clays, sandy clays, and sand in Virginia, the District of Columbia, Maryland, Delaware, Pennsylvania, and in the subsurface of New Jersey. It preserves fossils such as plants and molluscs dating back to the Cretaceous period.
The Java Formation is a geologic formation in Kentucky, New York, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia. It preserves fossils dating back to the Devonian period. The formation comprises the Pipe Creek Shale, Wiscoy Sandstone Member in New York, and Hanover Shale Member except in Tennessee.
The Alum Bluff Group is a geologic group in the states of Georgia, Florida, and Alabama. It preserves fossils dating back to the Neogene period.
The Littleton Formation is a geologic formation in New Hampshire. It preserves fossils dating back to the Devonian period. The formation is exposed on several of New Hampshire's most prominent mountains, including Mount Washington and the northern Presidential Range, Mount Moosilauke, and Mount Monadnock.
The Franconia Formation is a geologic formation in the upper mid-western United States, with outcroppings found in Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, Ohio, and Wisconsin. It preserves fossils dating back to the Cambrian period. It was named the Franconia Formation due to the first published documentation of exposures in vicinity of Franconia, Minnesota in the 1897 Ph.D. dissertation by Charles P. Berkley at the University of Minnesota titled Geology of the St. Croix Dalles. The Franconian stratigraphic stage was named after this formation.
The Weches Formation is a greensand, slay, and shale geologic formation in Louisiana and Eastern Texas. It preserves fossils dating back to the Paleogene period, specifically the Eocene.
The De Queen Formation, formerly known as the DeQueen Limestone Member is a Mesozoic geological formation located in southwestern Arkansas and southeastern Oklahoma in the United States. Fossil sauropod and theropod tracks have been reported from the formation. It preserves fossils dating back to the Cretaceous period, particularly the Albian age.
The Newcastle Sandstone is a geologic formation in Wyoming, United States. It preserves fossils dating back to the Late Cretaceous period.
The Red Peak Formation is a geologic formation in Wyoming belonging to the Chugwater Group. It preserves fossils dating back to the Triassic period.
The Virgin Formation is a geologic formation in Utah. It preserves fossils dating back to the Triassic period.
The Port Orford Formation is a geologic formation in Oregon. It preserves fossils. It consists of beds lying unconformably between the Empire Formation and overlying terrace deposits. The formation is composed of a basal bed of buff (yellow-brown) sand, overlain by a layer of conglomerate, and layer of rusty sand grading upward into blue-gray argillaceous sand, which is then truncated by the sea, on top of which are the Elk River Beds. The name was proposed by Ewart M. Baldwin in 1945.
The Kern River Beds Formation is a Neogene Period geologic formation in the southeastern San Joaquin Valley, within Kern County, California.
The Harold Formation is a geologic formation in the Central Mojave Desert, west of Victorville and north of the San Gabriel Mountains, in eastern San Bernardino County, Southern California.
The Turlock Lake Formation is an Early Pleistocene geologic formation in the Sierra Nevada foothills in Sacramento County, California. Cities in/over the formation's area include Citrus Heights, Carmichael, and Roseville.
The Puget Group is a geologic group in Washington (state). It preserves fossils dating back to the Paleogene period.
The Pensauken Formation is a geologic formation in Delaware, Maryland, New Jersey, and Pennsylvania, of Late Tertiary age.
