The Devonian Ocean Floor Post-Bolide
Structure of Devonian Coast

Devonian Sea Bottome

After the bolide struck, the ocean floor near the impact site was torn apart and re-organized. This catastrophic local event altered the topography of the ocean floor, creating a more complex marine environment with localized shallow and deep water depths. Evidence for a more complex ocean floor can be seen in the variety of sedimentary rock types and fossils deposited through the impact region. The varying topography of the ocean floor in some ways favored the Devonian marine life, especially reef-building organisms that prefer to settle and grow along topographic highs within the Earth’s oceans.
