The Escabrosa Limestone is a geologic formation in Arizona left behind from an ancient sea from some 330 million years ago. Layers of the sediment left by the sea hardened into a what is called a "strata." It has preserved fossils dating back to the Mississippian subperiod.
Rainwater has seeped into the limestone, eroding and dissolving the rock into walkable passageways. These are called the "Kartchner Caverns" and are considered a living cavern since they are still growing.
The Aymestry Limestone is a fossiliferous limestone of Gorstian age deposited in a warm shallow sea near the eastern margin of the Iapetus Ocean. It occurs in England in the Ludlow Group, between the Upper and Lower Ludlow Shales. It derives its name from Aymestrey (sic), Herefordshire, where it may be seen on both sides of the River Lugg. It is well developed in the neighbourhood of Ludlow and occupies a similar position in the Ludlow shales at Woolhope, the Abberley Hills, May Hill and the Malvern Hills.
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 Dundee Limestone is a geologic formation in Michigan, Ohio and Ontario. It preserves fossils dating back to the Devonian period.
The Golconda Formation is a geologic formation in Kentucky. It preserves fossils dating back to the Carboniferous period. In Indiana, the Golconda, it is called the Golconda Limestone and is part of the Stephensport Group.
The Harrodsburg Limestone is a geologic formation, a member of the Sanders Group of Indiana Limestone, of Mississippian age. It was named for Harrodsburg in southern Monroe County, Indiana by T. C. Hopkins and C. E. Siebenthal. It is made up primarily of calcarenite and calcirudite. It also may include some beds of dolomite and shale.
The Laurel Formation, also known as the Laurel Limestone or the Laurel Dolomite, is a geologic formation in Indiana and Kentucky. It preserves fossils dating back to the Silurian period.
The Mosheim Limestone is a geologic formation in Virginia. It preserves fossils dating back to the Ordovician period.
The Miami Limestone, originally called Miami Oolite, is a geologic formation of limestone in southeastern Florida.
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 Burlington Limestone is a geologic formation in Missouri, Iowa and the Midwest region. It preserves fossils dating back to the Mississippian subperiod.
The Cape Limestone is a geologic formation in Missouri. It preserves fossils dating back to the Ordovician period.
The Troublesome Formation is a geologic formation in Colorado. It preserves fossils dating back to the Neogene period. It consists of Pale shades of pink, tan, gray, green, and white interbedded siltstone and mudstone, less abundant arkosic sandstone and conglomerate, and sparse limestone and altered crystal-vitric ash and tuff; generally poorly consolidated. It includes atypical deposits containing abundant pink, granitic cobbles and boulders along the western parts of the outcrop in the west-central and southwestern parts of the Granby Quadrangle, Fossil mammals from three sites indicate a late Oligocene age.
The Black Prince Limestone is a geologic formation in Arizona. It preserves fossils dating back to the Carboniferous period.
The Mural Limestone is a geologic formation of the Bisbee Group in Arizona and Mexico. It preserves fossils dating back to the Cretaceous period.
The Ancholme Group is a geologic group in England. It preserves fossils dating back to the Jurassic period. It has previously been referred to as the Ancholme Clay Group. The group consists of predominantly grey, marine mudstone and silty mudstone with beds of argillaceous limestone nodules. In parts of its range it interfingers with the Corallian Group, which predominantly consists of coralliferous limestones.
Tasbacka is an extinct genus of sea turtle containing several species.
The Anderdon Limestone is a geologic formation in Michigan. It preserves fossils dating back to the Devonian period.
The Rockport Quarry Limestone is a geologic formation in Michigan. It preserves fossils dating back to the Devonian period.
The Squaw Bay Limestone is a geologic formation in Michigan. It preserves fossils dating back to the Devonian period. The ammonoid Koenenites has been found in this formation.
