Antediluvian Floating Forests?

Some peculiarities of the plant fossil record are best explained by the Noachian flood model, and by existing floating marshes.
Certain rock layers hold fossils of unique and extinct plants that had hollow tube-like structures, which probably made them lightweight and able to float on peat mats before they were buried and fossilized. A recent video from the United States Geological Survey featured scientists studying a giant modern floating marsh field in Louisiana.2 This unusual ecosystem can give a glimpse into the world as it might have been before Noah's Flood and can help explain a peculiar feature of the plant fossil record.
