Not when kids are being taught to sing-along to this sort of hogwash:
Interesting theory, but erm... no.
Flood = rocks? I think not. Land/mudslides and volcanoes, maybe... but correct me if I'm wrong, but I was always under the impression that floods = lots and lots of water.
And drowning may mean carcasses sink, but eventually the gases in the abdomen would cause bloating and the body would float. Depending on the temperature and alkalinity of the water and marine activity, the rate of decomposition may range from several days to several weeks. None of which would result in fossilisation of dinosaurs, and certainly not to the degree of which certain species have been found to specific areas.
