The Downton Castle Sandstone is a geologic formation in England. It preserves fossils dating back to the Silurian period. As its name would suggest the formation predominantly consists of sandstone with minor siltstone and mudstone. [1] The oldest known Trigonotarbid Palaeotarbus is known from the formation.
The Hinton Formation is a geologic formation in West Virginia. It preserves fossils dating back to the Carboniferous period. It is mainly made up of limestone, sandstone, and shale.
The Williamsport Sandstone is a sandstone geologic formation in West Virginia, Virginia, Pennsylvania, and Maryland. the formation includes the Cedar Creek Limestone member. Near Cumberland, Maryland it includes the Cedar Creek Limestone member. It preserves fossils dating back to the Silurian period.
The Sylvania Sandstone is a geologic formation in Ohio and Michigan. Its type locality is Sylvania, Ohio. It preserves fossils dating back to the Devonian period.
The Cuyahoga Formation is a geologic formation in Ohio. The age of the formation is difficult to determine, because of a lack of diagnostic fossils. Roughly, the formation dates from the Late Kinderhookian to the Middle Osagean. Eight members are recognized, among them the Orangeville Shale, Sharpsville Sandstone, and Meadville Shale.
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 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 Jordan Sandstone is a geologic formation in Wisconsin. It preserves fossils dating back to the Cambrian period.
The Everton Formation is a geologic formation in northern Arkansas that dates to the middle Ordovician Period. Unconformities separate this formation from the underlying Powell Formation and the overlying St. Peter Sandstone Formation. Named for the town of Everton in Boone County, Arkansas in 1907, the Everton Formation is composed primarily of dolomite, limestone, and sandstone.
The Sawatch Formation is a geologic formation in eastern Colorado. It is a sedimentary sequence formed approximately 530 million years ago during a marine transgression. It preserves fossils dating back to the Cambrian period. It is composed of glauconitic and quartz-rich sandstone.
The Harding Sandstone is a geologic formation in Colorado. It preserves fossils dating back to the Ordovician period.
The Maroon Formation is a geologic formation in Colorado. It preserves fossils dating back to the Permian period. It is the primary formation of sandstone that lends the vivid red color to the hills around Glenwood Springs, Colorado.
The Whiteaves Formation is a geologic formation in British Columbia. It preserves fossils dating back to the Jurassic period.
The Pendle Grit is a geologic formation in England. It is a coarse Carboniferous age sandstone assigned to the Millstone Grit Group, and preserves fossils dating back to the Carboniferous period. The formation takes its name from Pendle Hill in Lancashire where it forms the sloping plateau summit.
The Scremerston Formation is a geologic formation in England. It preserves fossils dating back to the Carboniferous period.
The Sandringham Sandstone is a geologic formation in England. It preserves fossils dating back to the Cretaceous period.
The Spilsby Sandstone is a geologic formation in England. It preserves fossils dating back to the Cretaceous period.
The Carstone Formation is a geological formation in England. It preserves fossils dating back to the Albian stage of the Cretaceous period. It predominantly consists of "greenish-brown, thick-bedded, cross-bedded, oolitic ferruginous sandstone".
The Baggy Sandstones is a geologic formation in England. It preserves fossils dating back to the Devonian period.
The Princeton Sandstone is a geologic formation in West Virginia. It preserves fossils dating back to the Carboniferous period.
The Hopeman Sandstone Formation is a geologic formation in Scotland. It preserves fossil footprints and body fossils from the Guadalupian Epoch in the Late Permian, to the Early Triassic, It preserves fossils and fossil footprints from various extinct animals such as pareiasaurs and dicynodonts, which are collectively often referred to as the Elgin Reptiles.
