	Palaeos Paleozoic: Carboniferous: The Serpukhovian Epoch
		The Serpukhovian is the last of the three ages that make up the Mississippian Epoch.
		This is the Age from which come the remarkable tetrapods of East Kirkton and the Dora Bone Beds, as well as the wonderful chondrichthyan fauna of Bear Creek.
		Interestingly, these dramatic climate changes in the Late Serpukhovian occurred at just about the same time as the major evolutionary events of the Age: the sudden spread of winged insects, the evolution of protoamniotes (e.g.

		Serpukhovian environments indicate the platform constricted significantly from the north and south to become relatively equidimensional and centered about the present structure.
		The platform thickened dramatically during the Serpukhovian, either responding to a rapid sea level rise or due to tectonic movement.
		A thick, but narrow, reef margin is confirmed for the Serpukhovian.

		In this paper, we present a diagenetic and porosity evolution of the Visean part of the Mississippian carbonate platform that may lead to the development of new exploration fairways in the region.
		A diagenetic model is proposed in which ooid and crinoid grainstones may have a reservoir potential if hydrocarbon migration occurred before the end of the Serpukhovian, prior to complete occlusion of porosity.
		The two facies investigated are Waulsortian-type buildups and overlying ooid and crinoid grainstones that form regularly alternating packages in the thick upper Visean succession.

		The Bashkirian - Serpukhovian boundary represents a major change in the style of deposition and equates with a time gap.
		Four Serpukhovian sequences of more skeletal-rich environments form another composite sequence.
		Three composite sequences within the Late Visean contain grainstone-packstone cycles that are similar to those of the Serpukhovian.

		An initial broad Late Devonian platform was followed by punctuated backsteps during the Tournaisian and Viséan.
		The Serpukhovian is characterized by several kilometers of platform progradation.
		Late Viséan and Serpukhovian reservoirs have distinctive seismic facies, and production/performance characteristics.

		This 1.5 increase was probably caused by increased organic carbon burial, whereas the additional ~1.5 shift in European sections likely reflects changes in ocean circulation patterns associated with the closing of the Equatorial Seaway.
		C divergence between North America and Europe, the isolation of the Paleotethys began in the late Chesterian (Serpukhovian).
		O record can also be separated into the three stages.
