REUNITE GONDWANALAND!
Ewww...on second thought, let's not.
Dr. Walt Brown's Hydroplate is just another variant. He hand-waves away the apparent faunal succession from prokaryotes to eukaryotes to trilobites to dinosaurs to mammals to man as an artifact of "hydraulic sorting." (So why aren't the trilobites up with the pill bugs?) He has the continents racing about after the flood, whacking into each other like carnival bumper cars at energies that would have melted everything in sight.
He's not so much a charlatan as a buffoon.
