Meso- means middle. Clearly something is different about Mesozoic sediment compared to Paleozoic and Cenozoic. Paleozoic was the deluge. Mesozoic was the period of time when the water remained high on the Earth.
The timeline for Noah's flood comes directly from scripture and this is the framework that we use to interpret evidence from the stratigraphic column.
We finished a step-by-step deconstruction of the Paleozoic and Mesozoic, but there’s another issue that we’re going to account for: the Iridium anomaly.
"Continued inundation of low-lying continents?" That sounds like a world-wide flood. In fact, it's a way of saying world-wide flood without using the words world-wide flood. It's an ecosystem, not a period of time.
Noah's flood was not only a world-wide catastrophe, it was also a process which involved several stages. It gives us a way to account for the stratigraphic column, Cambrian through Quaternary.
