Lower and lowermost Middle Ordovician rocks in that area represent a condensed sequence, resulting from slow sedimentation in a relatively shallow epicontinental sea that was starved of siliciclastic sediments (Jaanusson 1973).
It is notable that the main part of the Upper Yangtze region appears to be covered by a relatively flat and shallow epicontinental sea, which provided the palaeogeographic setting for the deposition of the very thin Kuanyinchiao Beds with the widely distributed Hirnantia shelly fauna.
In the Middle Ordovician and early Late Ordovician, the western part of the East European Platform was covered by a shallow, epicontinental sea and was slowly subsiding.
During this epoch, despite dramatic water level fluctuations of the ancient epicontinental seas, the clade avoided extinction (Huber, 1998).
During the mid-Cretaceous, dysoxic and anoxic conditions (oceanic anoxic events: OAEs) developed in oxygen minimum zones along the continental margins of the tropical Tethys Sea, in restricted epicontinental seas, and in basins of the widening North and South Atlantic Ocean basins (Leckie et al, 2002).
provide a detailed study of enigmatic fossils in Upper Silurian sequences of Bolivia and conclude that they indicate high productivity at high paleolatitudes in Late Silurian epicontinental seas.
These highlands were presumably never inundated by epicontinental seas. Hence species of freshwater fishes endemic to this region likely diversified over a longer period of time than species from the surrounding lowlands.
From that, they determined whether these occurrences were from epicontinental seas or open-ocean-facing settings, and they then compared extinction and origination rates in the two settings throughout the interval.
