That ambitious undertaking is certainly more than I can accomplish is this short talk. All I can do is to offer some examples in the hope of inspiring others to join me in critically reviewing the tools of our trade. It is easy enough to question any of our models, just as we identify the needs of a congested airport. But in both instances, we need to offer some remedies, some possible new directions, perhaps even a major remodeling. Revisions to some of our long-established models are well underway.
Marine carbonates are no longer exclusively warm water.
Stromatolites can form well below the intertidal zone. Graded beds alone are insufficient criteria for deposition from density currents. Quaternary shelf deposits are not adequate models for the sediments of epeiric seas. Coral buildups are not restricted to warm shallow equatorial seas. I will present three models, which I believe deserve serious review.
