The Depositional Record, EarlyView.The Bisperode section is one of the most expanded and complete sections with shallow‐marine Oxfordian strata in the LSB. This study provides a reference record for shallow‐marine settings and allows for the correlation of the strata from the LSB with Oxfordian deposits distributed elsewhere in the world.

The Depositional Record, EarlyView.Bermuda patch reefs development was primarily controlled by massive coral framework construction, and variation in environmental energy, turbidity and bioerosion. These factors shaped the size, diversity and preservation of the framework, leading to a suppressed, steady vertical accretion.
