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.
The reconstructed topographic maps indicated that the Upper Yangtze region was a semi-closed, shallow epicontinental sea during the Hirnantian.
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.
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.
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.
As recorded elsewhere, sediments deposited in the shallow epicontinental seas that extended over northeastern Mexico also indicate that general conditions of sedimentation favored the preservation of organic carbon from the Jurassic to the Cretaceous.
This was identified as the supratidal zone where carbonate mud-flats were exposed to alternating episodes of wetting and more prolonged drying; hence, this represents a setting above average sea level, assuming a microtidal coast, typical of most epicontinental seas (Allison & Wells 2006).
