The Kope Formation is one of the three component bedrock formations of the Maquoketa Group that primarily consists of shale (75%) with some limestone (25%) interbedded.
 In general, it has a bluish-gray color that weathers light gray to yellowish-gray and it occurs in northern Kentucky, southwest Ohio, and southeast Indiana, United States.
The Roxbury Conglomerate, also informally known as Roxbury puddingstone, is a name for a rock formation that forms the bedrock underlying most of Roxbury, Massachusetts, now part of the city of Boston.
 The bedrock formation extends well beyond the limits of Roxbury, underlying part or all of Quincy, Canton, Milton, Dorchester, Dedham, Jamaica Plain, Brighton, Brookline, Newton, Needham, and Dover.
 It is named for exposures in Roxbury, Boston area.
The Boonton Formation is a mapped bedrock unit in New Jersey, formerly divided between the Boonton and Whitehall beds of the defunct Brunswick Formation.
 It is named for the town of Boonton, New Jersey, which is near where its type section was described by paleontologist Paul E. Olsen.
Residuum is often used to refer to the soil and subsoil that forms as the result of long weathering over carbonate rocks (limestone and dolomite) bedrock.
 The term is more specific than regolith, which refers to all unconsolidated material, including transported sediments such as sand or alluvium, but less specific than saprolite which commonly refers to weathered material retaining details or structural features of the bedrock.
 In limestone terrains the boundary between bedrock and residuum is commonly very sharp, but may be highly irregular, defining pinnacles and even isolated blocks of fresh bedrock surrounded by reddish residual silts and clays derived from its decomposition.
 Resistant materials such as chert, silicified fossils, or beds of sandstone remain and may concentrate on the surface as float.
The Crevasse Canyon Formation is a coal-bearing Cretaceous bedrock formation in New Mexico and Arizona.
Plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks".
 This occurs in a type of glacier called a "valley glacier".
 As a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock.
 The freezing and thawing action of the ice enlarges, widens, or causes further cracks in the bedrock as it changes volume across the ice/water phase transition (a form of hydraulic wedging), gradually loosening the rock between the joints.
 This produces large pieces of rock called joint blocks.
 Eventually these joint blocks come loose and become trapped in the glacier.
The Passaic Formation is a mapped bedrock unit in Pennsylvania, New Jersey, and New York.
 It was previously known as the Brunswick Formation since it was first described in the vicinity of New Brunswick, New Jersey.
 It is now named for the city of Passaic, New Jersey, which is near where its type section was described by paleontologist Paul E. Olsen.
Hallopora is an extinct genus of bryozoans.
 They can be found in Ohio, Indiana, and Kentucky of the Midwestern United States, commonly in the Ordovician Kope Formation.
The Point Lookout Sandstone is a Cretaceous bedrock formation occurring in New Mexico and Colorado.
The Silurian Shawangunk Formation is a mapped bedrock unit in eastern Pennsylvania, New Jersey, and New York.
 It is named for the Shawangunk Ridge for which it is the dominant rock type.
 The division of the Shawangunk between the Tuscarora Formation and Clinton Group has not been conclusively determined.
 The shift of nomenclature currently has the divide between Hawk Mountain and Lehigh Gap.

Question: Hallopora can be commonly founded in what type of bedrock formation?
Answer: Kope Formation
